Using CPE and PVC blended plastic doors and windows, the elasticity, toughness and low temperature performance are greatly improved, and the weather resistance, heat resistance and chemical stability are good.
Since the CPE molecule does not contain double chains, it has good weather resistance, flame resistance, thermal stability better than PVC, low cost and excellent performance.
Formerly known as Longyang Chemical, was established in 2003, is a professional manufacturer of plastics, rubber auxiliaries, is a collection of scientific research, development, sales, service...
Plasticizers and antioxidants used in rubber and plastics are more effective in semi-rigid and soft PVC, especially in injection molding and secondary processed products.

2024-Sep-WedWhen producing plastic products, we use a lot of stabilizers, among which composite stabilizers are the most widely used. Even though lead salt stabilizers are inexpensive and have good thermal stability, they have been widely used. However, their lead salt powder is small, and their dust ca...
2024-Sep-ThuBecause PVC processing aids are highly compatible with PVC and have a high relative molecular weight (about (1-2) × 105-2.5 × 106g/mol) and no coating powder, they are subject to heat and mixing during the molding process. They first soften and tightly bond the surrounding resin particles. T...
