PVC(Polyvinyl chloride) Gray HexagonHead Screws

A substitution reaction can make polyvinyl chloride (PVC) of ethylene, chlorine, and catalyst. Because of its fire- and heat-resistant properties, PVC is used in a wide variety of products in a wide variety of industries: wire jackets, fiber-optic jackets, shoes, handbags, bags, ornaments, signs and billboards, architectural upholstery, furniture, wall hangings, wheels, hoses, toys, curtains, roll-up doors, paramedical supplies, gloves, freshness paper for certain foods, specific fashions, etc.

PVC is an amorphous structure of white powder small degree of branching, glass transition temperature of 77 ~ 90 ℃, 170 ℃ or so began to decompose, poor stability to light and heat, above 100 ℃ or after a long period of exposure to sunlight, it will decompose and produce hydrogen chloride, and further autocatalytic decomposition, resulting in discoloration, the physical and mechanical properties also rapidly decline in practical applications must be added to stabilizers to improve the stability of heat and light. A stabilizer must be added to improve heat and light stability in practical applications.
