PVC-WHAT IS PVC Futures?
pvc futures are futures pvc as a variety of subject matter.
Basic physical and chemical properties of PVC PVC (polyvinyl chloride), referred to as PVC, as a thermoplastic resin. And steel, timber, cement, adding that the four basic building materials, with the PP, PE, ABS, PS and said the five common resin, is the largest Chlor-Alkali Industry organic consumption of chlorine products. PVC has a stable physical and chemical properties, insoluble in water, alcohol, gasoline, gas, water vapor leakage is low; at room temperature, may be resistant to any concentration of hydrochloric acid, 90% or less of sulfuric acid, 50-60% of nitric acid and 20% or less The caustic soda solution, with a certain degree of resistance to chemical corrosion; pairs of salts fairly stable, but can be dissolved in ether, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons and other organic solvents. In addition, POVC of light, poor thermal stability at 100 ℃ and above, or by prolonged sun exposure, it will decomposition of hydrogen chloride, and further auto-catalytic decomposition, discoloration, physical and mechanical properties decreased rapidly, and therefore must be included in the practical application stabilizer to raise awareness of heat and light stability.
