Rubber kraal mat today small make up teach you how to distinguish between what is PVC what is organic board? PVC is a kind of plastic, also is the chemistry of polyvinyl chloride (PVC), is composed of vinyl chloride polymerization under the action of a initiator of the thermoplastic resin. The organic board, that is, the PS board is a kind of thermoplastic amorphous resin. PS plate is colourless, odourless, tasteless and shiny, light weight and low price, low water absorption, good color, stable chemical properties, excellent electrical insulation, high frequency insulation is preferred, have a certain impact resistance, weather resistance and aging resistance, good pervious to light, ability general of chemical corrosion, mechanical processing, hot bending, screen printing, blister. PVC is characteristic of stable not easy to be acid, alkali corrosion; Comparison on heat tolerance; Polyvinyl chloride (PVC) with a flame retardant ( Flame retardant value of more than 40) , high resistance to chemicals ( Resistance to strong hydrochloric acid, sulfuric acid concentration is 90%, the concentration of 60% concentration of nitric acid and 20% sodium hydroxide) The advantages of, good mechanical strength and electrical insulation. Polyvinyl chloride (PVC) light and heat stability was poor. Has the stable physical and chemical properties, insoluble in water, alcohol, petrol, gas, water vapor leakage low; At room temperature can be resistant to any concentration of 50-90% hydrochloric acid, sulfuric acid, under Under 60% nitric acid and 20% caustic soda solution, have a certain resistance to chemical corrosion resistance; Salts are quite stable, but fat can dissolve in ether, ketones, chlorinated hydrocarbon and aromatic hydrocarbon solvents.
