What are the characteristics of the seal strip Manhole Cover?

PVC products have lower cost and superior comprehensive performance. Our company's manhole cover products are equipped with all kinds of extruded rubber strips and hoses. PVC is made of polyvinyl chloride resin as the main raw material, and an appropriate amount of anti-aging agent is added to form and process.
Its characteristics are mainly as follows:
1. Light weight, heat insulation, heat preservation, moisture proof, flame retardant, acid and alkali resistance, corrosion resistance;
2. Stability, dielectric properties, durability, anti-aging, easy to weld and bond;
3. Strong bending strength and impact toughness, and high elongation at break;
4. Can be processed by kneading, kneading, pulling, pelletizing, extrusion or die-casting, etc., to meet the needs of various profile specifications;
5. The surface is smooth, bright and decorative.
Mainly applicable to:
a. Various profiles, anti-collision strips used on various types of doors and windows;
b. Shock-absorbing edge strips used in various cabinets, partitions, and special floors;
c. The shower room, bathroom, health equipment and other scraping strips for waterproofing, edge banding;
The blending of PVC and NBR has successfully solved some of the problems of plasticizer migration and weathering resistance, so that PVC has a new and higher balance point in performance and price, which combines their respective Superiority, and maintain the original characteristics of the rubber characteristics of PVC.
Its characteristics are as follows:
1, PVC + NBR (rubber) Mainly improve performance: oil resistance, aging resistance, good elasticity. Widely used in contact with oily substances. Such as motorcycle tubing, etc.;
2, PVC + EPDM (ethylene propylene diene monomer) Mainly improve performance: resistant to aging, acid and alkali, good elasticity. Widely used in contact with water. Such as: door and window curtain wall, car window seal, submarine window seal, etc.;
3, PVC + cold or heat-resistant materials: mainly improve cold and temperature resistance: -45 ° C ~ 110 ° C.
