Compound manhole cover sealing strips are mainly made of PVC rubber, which has low cost and excellent comprehensive performance. Our manhole cover products are equipped with various types of extruded rubber strips and hoses. PVC rubber is based on polyvinyl chloride resin as the main raw material. Anti-aging agent, formed by processing.
Its characteristics are mainly as follows:
1. Light weight, heat insulation, heat preservation, moisture resistance, flame retardant, acid and alkali resistance, and corrosion resistance;
2. Good stability and dielectric properties, durable, anti-aging, easy to weld and adhere;
3. Strong bending strength and impact toughness, and high elongation when broken;
4. Yes. It can be processed and shaped by kneading, mixing, pulling, pelletizing, extrusion or die casting, etc., which can meet the needs of various profile specifications;
5.Smooth surface, bright color and rich decoration.
Mainly applicable to:
a. Anti-collision tape for various profiles and doors and windows;
b. Shock-absorbing edge banding used in various cabinets, partitions and special floors;
c. Water-proof wipers and edge bands for shower rooms, bathrooms, and health equipment;
The blending of PVC and NBR successfully solved some of the problems of plasticizer migration and weathering resistance, thereby giving PVC a new and higher balance in performance and price. Superiority, while maintaining the original characteristics of PVC.
Its characteristics are as follows:
1. PVC + NBR (rubber) mainly improves performance: oil resistance, aging resistance, good elasticity. It is widely used in contact with oil. Such as motorcycle tubing;
2. PVC + EPDM (Ethylene-propylene-diene rubber) Mainly improve performance: aging resistance, acid and alkali resistance, good elasticity. Widely used in contact with water. Such as: door and window curtain wall, car window seal, submarine window seal, etc .;
