What are the Ingredients of CPVC solvent cement? PLASTOCHEM

 

CPVC cement is used in pipes and fittings for strong plumbing.  It's a solvent-based product that chemically fuses CPVC materials together by temporarily softening their surfaces. Here's a general process for how PLASTOCHEM CPVC cement made in India:

About cpvc solvent cement

Ingredients:

1. Resins: The key ingredient is CPVC resin, which is essentially a polymer that has been chlorinated to improve heat resistance and strength.
2. Solvents: The solvents in the cement (such as tetrahydrofuran (THF), methyl ethyl ketone (MEK), or acetone) dissolve the surface of the CPVC pipe and fitting. These solvents evaporate after application, leaving the bonded surfaces fused.
3. Stabilizers and Additives: These components improve the cement’s performance and longevity. They include stabilizers to prevent degradation during storage, fillers to adjust viscosity, and colorants for identification.

Manufacturing Process:

1. Mixing: The CPVC resin is mixed with a blend of solvents in a controlled environment. The solvents dissolve the resin, creating a homogeneous, viscous solution.
2. Addition of Stabilizers and Additives: Stabilizers and other additives are blended into the solution to achieve the desired consistency, performance, and color.
3. Quality Control: The mixture undergoes tests to ensure that it meets required specifications such as viscosity, drying time, and bonding strength.
4. Packaging: The finished cement is packaged in airtight containers to prevent solvent evaporation and maintain its effectiveness.

Application:

When applied to CPVC pipes and fittings, the cement softens the surfaces. Once joined, the solvents evaporate, leaving behind a strong, permanent bond between the parts.
