The natural color is slightly yellow translucent and shiny. Transparency is better than polyethylene and polystyrene, worse than polystyrene. Depending on the amount of additives, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and they have a sticky feel. , And lower than polypropylene, there will be whitening phenomenon at the inflection point.
Relative density 1.4
Low solubility, easily soluble in ketones, esters and chlorinated hydrocarbon solvents. High molecular weight is difficult to dissolve.
Flame retardant (flame retardant value above 40), high chemical resistance (concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength and electrical insulation Good sex. However, its heat resistance is poor, with a softening point of 80 ° C, decomposition and discoloration starting at 130 ° C, and HCI precipitated.
Performance characteristics: This product is a white powder, which can be added with different additives according to different uses, showing different physical and mechanical properties. Its mechanical properties, corrosion resistance, dielectric properties, and chemical resistance are excellent.
| use: || Its products are used in various fields such as light industry, building materials, agriculture, daily life, packaging, electricity, utilities, etc., and are widely used in construction, transportation, machinery and meters, electronics, chemicals, agriculture, food packaging and other fields. |
