A brief introduction of PVC resin
What is PVC
Polyvinyl Chloride (PVC) resin is one of the most widely used thermoplastic polymers in the world, known for its versatility, durability, and cost-effectiveness.
PVC Resin Models and Differences
PVC resins are classified by polymerization degree (or K-value), which determines their strength and applications , their is a Quick Comparison Table for most commonly used PVC resin.
K-Value | Degree of Polymerization | Common Model | Primary Applications |
72-71 | 1251-1370 | SG-3/S-1300/DG-1300 | Soft products,hoses,cables |
70-69 | 1136-1250 | SG-4 | Films,sheets,synthetic leather |
68-66 | 981-1135 | SG-5/S-1000/ DG-1000S/HS-1000F | Pipes,profiles,fittings(most common) |
62-60 | 741-845 | SG-7 | Records,transparent sheets |
60-57 | 650-740 | SG-8/S-700/DG-700 | Transparent sheets, bottles, injection molding |
