PVC profile

PVC profile

PVC (Polyvinyl Chloride, short PVC), is China first, and world second large general type synthetic resin material, due to has excellent of difficult burning sexual, and wear sexual, and anti-chemical corrosion sexual, and integrated machinery sexual, and products transparency, and electric insulated sexual and the comparison easy processing, features, currently, PVC has became application area most widely of plastic varieties one, in industrial, and building, and agricultural, and daily life, and packaging, and power, and utilities, area are has widely application, And polyethylene (PE), polypropylene (PP), polystyrene (PS) and ABS are collectively referred to as the five common resins.

PVC is a non-toxic, odorless white powder. Its high chemical stability, good plasticity. Apart from a few organic solvents, a room temperature, is resistant to any concentration of hydrochloric acid, sulfuric acid, nitric acid and 20% 50~60% of the 90% the following the following caustic soda, salt is stable; poor thermal stability and light fastness of PVC, at more than 140 ° c starts to break down and release hydrogen chloride (HCl) gases, causing the PVC color. Excellent electrical insulation of PVC, generally will not burn, burn on the flame and emits HCl, but away from the flame that is self-extinguishing, is a "flame resistance," "fire performance" material. Based on the above characteristics, PVC is mainly used for producing profiles, profile, pipe and fittings, sheets, sheet, cable sheathing pipe, hard or soft, blood transfusion equipment and films, and other areas.
