PVC, UPVC and CPVC Solvent Cement Benefits and Pipe Fixing

CPVC stands for Chlorinated Polyvinyl Chloride, which is a type of plastic solvent helpful to make plumbing fixtures and fittings. CPVC Solvent is an alternative to copper or galvanized pipes because it resists corrosion from certain substances such as corrosive soil acids and salt. Unlike other plastics such as PVC rusts easily if put under the same conditions.

The Solvent is only slightly more expensive than chlorinated PVC, but it gives users many advantages, including eliminating all chlorine components from the building structure. Eliminating most health, fire and vapour hazards. Providing excellent adhesion properties. Providing easy cleanup after application; and providing an environmentally friendly product.

What is CPVC Solvent?

CPVC Solvent is a chemical product that is mainly white carbon and chlorine. And this solvent can dissolve PVC resins under low temperatures.

In the process of making PVC pipes, CPVC Solvent can accelerate the reaction between PVC resin and the other product. Thereby improving the process efficiency and reducing production costs. Which is highly in use in the PVC pipe manufacturing industry since 2013 years. This article will share CPVC Solvent benefits with you.

Types of CPVC Pipe Solvent

There are two types of solvents used in the CPVC pipe production process.

• In one, the solvent is applied and CPVC pipes are extruded.
• And, the second type is where solvent forms an integral part of plastic and pipe are produced simultaneously.

Once the solvent is evaporated from PVC plastic during production, it leads to the formation of pipes. This process uses environmentally friendly chemicals.

Application of CPVC pipe Solvent 

CPVC (Chlorinated Polyvinyl Chloride)is

1. Flexible
2. Strong
3. Easy to use

Although it is less expensive than PVC, it doesn’t have as many commercial uses and can be broken down by water and environmental factors.

• It has a higher pressure rating which makes it ideal for high water applications but also means that it needs more support in that same environment.
• The greatest benefit of using CPVC instead of PVC or ABS is its low-maintenance nature.
• The solvent is not toxic so you don’t need to worry about anyone getting hurt if they do get exposed to it.
• Another thing worth noting is that these solvents are non-flammable and are odourless. Although some companies claim their products smell like fruit when heated. There is nothing poisonous about their product.

What are the Uses of CPVC Solvent  

CPVC is a thermoplastic piping material with many of its uses due to its resistance to corrosion.

• CPVC offers a whole host of advantages when we compare it to other piping materials. make sure to use it safely in harsh environments.
• The biggest benefit of CPVC is that it is useful outside, in non-pressurized areas. Making it an ideal option for sprinkler systems and irrigation lines on properties. Or for commercial applications such as ponds and fountains.
• CPVC is a form of Polyvinyl Chloride that we use in numerous applications such as kitchen and bathroom applications.
• This product name is CPVC solvent because it has similar uses to PVC solvent. But with higher temperature capability.
• CPVC solvent is extensively helpful in manufacturing CPVC pipes.
• CPVC solvent is also used to make parts for CPVC pipes. Fittings and other construction items can be also helpful as a paint remover.

What are the Benefits of using CPVC Solvent?

CPVC solvent is easy to dissolve CPVC and plastic waste from end-users, fitters, construction industries and other users. The design is to help eliminate PVCs waste in landfills. By using it as a cleaner instead of throwing it away.

1. CPVC Solvent is for many applications including agricultural and pool water maintenance.
2. In agriculture, CPVC solvent can remove calcium deposits that are building up on valves or fittings within systems like irrigation lines or sprinkler heads.
3. It is common in use as joining pipe among different types of pipe to create an extra-strong material.

Which Pipes are suitable for CPVC Solvent?

CPVC pipes have different solvent fittings. The CPVC pipe is very helpful to supply water, gas, steam and oil in thermal power stations. This also includes the chemical industry, machinery and equipment manufacturing plants, paper making, textile industries and public facilities.

CPVC Solvent is a thinner that is helpful to dissolve CPVC resin. It’s a mixture of PVC, Polyvinyl Chloride (PVC) and Chlorine gas. The solvent is high in use in civil engineering plastic pipe products. It is dissolvable into PVC before getting cast into pipe form.

CPVC solvent can be helpful for all types of poly pipes such as

• Cold-water
• Hot water
• Central heating (radiator) pipe
• Drainpipe
• Spiral tube etc.

Even though CPVC solvent is a non-flammable product. It is not good for radiators. Clean CPVC solvent with water before applying it to other pipes.

We also have  a good range of UPVC Solvent

Safety Precautions with the use of CPVC Solvent

1. Ventilation of solvent is necessary to avoid fumes getting into the user’s eyes, skin or clothing.
2. Use air scrubbers and a fume hood or remove all sources of ignition such as open flames. Spark or hot surfaces during CPVC solvent use and until they get completely cool.
3. Avoid contact with skin, eyes and clothing.
4. If it should occur immediately flush contaminated areas with large amounts of water for at least 15 minutes.
5. For skin irritation: Wash thoroughly with soap and water after handling and apply ice to relieve pain or discomfort.
6. Keep away from heat, sparks, open flame or other sources of ignition.
7. Dispose of in accordance with federal, state and local regulations.
8. As with most chemicals used in industry, some exposure may be unavoidable if good industrial hygiene practices do not apply.
9. Wash hands thoroughly before eating, drinking or smoking.
10. Do not mix fire extinguishers with incompatible agents or solvents without proper engineering supervision. By experienced professionals familiar with both agents involved.

Thermoplastic CPVC vs thermoplastic PPCPC

The primary difference between CPVC and PPCP is in their chemical structures. As you might suspect, PPCP tends to be more brittle than CPVC. But more importantly, it has a lower heat deflection temperature (HDT).

As temperature increases, one of these plastics will bend before the other. If you are looking at a PVC solvent cement system such as those manufactured by Gruv-Glas or Polyken. Your system will only work reliably with CPVC pipe.

If you must use rigid PPCP, it recommends adding RPT200 to your system. This special resin helps dissipate stresses in your adhesive joint. And dramatically reduces stress-cracking problems. That can occur when using high-stiffness glue lines like RPT200 with PPCC joints.

CPVC Solvent Cement:

CPVC solvent cement is a type of adhesive specifically designed for use with Chlorinated Polyvinyl Chloride (CPVC) pipes and fittings. It creates a strong and permanent bond between two pieces of CPVC material, allowing leak-free plumbing and other systems to be constructed.

The solvent cement is typically made up of a mixture of solvents and resins that soften and melt the CPVC material at the joint, creating a chemical bond as the solvent evaporates. The cement is applied to the surfaces of the CPVC pipe and fitting that will be joined together, and the two pieces are then fitted tightly together to ensure a proper seal.

The bonding process works through a chemical reaction between the CPVC material and the solvent cement. As the solvent is applied to the joint, it begins to dissolve the surface of the CPVC material, creating a thin layer of melted plastic. This melted layer then mixes with the solvent cement to form a molten mixture, hardening as the solvent evaporates, creating a strong and permanent bond.

It is important to note that CPVC solvent cement requires careful preparation and application to ensure a successful bond. Factors such as temperature, humidity, and cleanliness can all affect the bonding process, so it is important to follow the manufacturer’s instructions carefully and to use the appropriate safety precautions when working with the cement.

The steps involved in the chemical bonding process of this solvent cement:

Here are the steps involved in the chemical bonding process of CPVC solvent cement:

1. Surface Preparation: The surfaces of the CPVC pipes or fittings to be joined need to be clean, dry, and free from dirt, dust, oil, grease, and any other contaminants. Use a cleaner or sandpaper to roughen the surfaces, which helps the solvent cement to penetrate the CPVC material and create a stronger bond.
2. Apply Primer: Once the surfaces are cleaned and roughened, apply a primer layer to the surfaces. The primer helps to soften the CPVC material, which makes it easier for the solvent cement to penetrate the material and create a stronger bond.
3. Apply Solvent Cement: Apply a liberal amount of solvent cement to the surfaces of the CPVC pipes or fittings that will be joined. Be careful not to apply too much, as this can cause the cement to run or drip, weakening the bond.
4. Join the Pieces: Once the solvent cement is applied, join the two pieces together and hold them in place for at least 30 seconds. The pieces should be held together until the cement has started to harden and set.
5. Allow to Cure: Once the pieces are joined, allow the cement to cure for at least 24 hours before using the pipes or fittings.

The chemical bonding process of this solvent cement:

The chemical bonding process of this solvent cement involves the following steps:

1. Dissolution: The solvent in the cement starts to dissolve the surface of the CPVC material. This dissolving process creates a small amount of heat that helps to melt the surface of the CPVC material.
2. Mixing: The melted surface of the CPVC material mixes with the solvent cement, forming a molten mixture.
3. Evaporation: As the solvent evaporates, the molten mixture hardens, creating a strong and permanent bond between the two pieces.
4. Crosslinking: The resins in the solvent cement crosslink with the CPVC material, creating a chemical bond that is very strong and durable.

Overall, this solvent cement’s chemical properties and bonding process create a very strong and permanent bond between CPVC pipes and fittings. However, following the manufacturer’s instructions carefully is important to ensure a successful bond.

 Steps and tips for using CPVC solvent cement correctly:

Here are some steps and tips for using CPVC solvent cement correctly and achieving a successful bonding:

1. Prepare the Surface: Make sure that the surfaces of the CPVC pipes and fittings are clean, dry, and free of any contaminants such as dirt, dust, oil, or grease. Use a cleaner or sandpaper to roughen the surfaces, which helps the solvent cement to penetrate the CPVC material and create a stronger bond.
2. Apply Primer: Once the surfaces are clean and roughen, apply a primer layer to the surfaces. The primer helps to soften the CPVC material, which makes it easier for the solvent cement to penetrate the material and create a stronger bond.

• Apply Solvent Cement: Apply the solvent cement to the surfaces of the CPVC pipes or fittings that will be join. Use a brush or applicator to apply a liberal amount of solvent cement to both surfaces. Be careful not to apply too much, as this can cause the cement to run or drip, weakening the bond.

1. Join the Pieces: Once the solvent cement is applied, join the two pieces together and hold them in place for at least 30 seconds. The pieces should be held together until the cement has started to harden and set.
2. Allow to Cure: Once the pieces are joined, allow the cement to cure for at least 24 hours before using the pipes or fittings.

Tips for successful bonding:

• Read and follow the manufacturer’s instructions carefully.
• Make sure that the ambient temperature and humidity are within the recommended range.

• Avoid working in direct sunlight or high temperatures, which can cause the cement to dry too quickly.

• Make sure that the surfaces are completely dry before applying the cement.
• Use a clean brush or applicator to apply the cement, and avoid contaminating the cement with dust or dirt.
• Do not use excess cement, which can cause the cement to run or drip and weaken the bond.

• Hold the pieces together firmly for at least 30 seconds after joining to ensure a strong bond.
• Allow the cement to cure for at least 24 hours before using the pipes or fittings.

These steps and tips can achieve a strong and durable bond with CPVC solvent cement.

Conclusion

CPVC is durable and safe, which makes it a popular choice for plumbing projects. However, CPVC requires special tools, equipment and expertise when working with it. Because of these challenges to using CPVC. Solvent weld fittings are a preference for professionals.

They are also easier to work with than other options because of their plastic nature. PVC solvent weld fittings help in both potable water and non-potable water applications.
