Types of PVC Resin

1. Suspension Grade PVC: Produced via suspension polymerization, this type is ideal for rigid applications such as pipes, fittings, and profiles due to its superior mechanical strength and chemical resistance.

2. Emulsion Grade PVC: Manufactured through emulsion polymerization, it offers flexibility and finds use in coatings, adhesives, and flooring where flexibility and adhesion are critical.

3. Off-Grade PVC: Refers to PVC resin that fails to meet standard specifications due to minor impurities or inconsistencies. It is typically recycled or used in non-critical applications to reduce costs.

4. CPVC: Chlorinated polyvinyl chloride is a thermoplastic produced by chlorination of PVC resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
