Polyvinyl chloride (PVC) is an initiator of vinyl chloride monomer (VCM) in peroxide and azo compounds, or a polymer polymerized by the radical polymerization reaction under light and heat . Vinyl chloride homopolymer and vinyl chloride copolymer collectively referred to as vinyl chloride resin.
So what are the benefits of PVC Gloves?
1. PVC has a flame retardant (flame retardant value of 40 or more), high chemical resistance (resistance to concentrated hydrochloric acid, the concentration of 90% sulfuric acid, the concentration of 60% nitric acid and 20% sodium hydroxide concentration) Mechanical strength and good electrical insulation advantages.
2. PVC light, heat stability is poor. The softening point is 80 ° C and begins to decompose at 130 ° C. In the case of non-heating stabilizer, polyvinyl chloride began to decompose at 100 ℃, more rapid decomposition above 130 ℃.
3. Stable physical and chemical properties, do not dissolve in water, alcohol, gasoline, gas, water vapor leakage is low; at room temperature resistant to any concentration of hydrochloric acid, sulfuric acid below 90%, 50-60% nitric acid and 20% The following caustic soda solution, has a certain resistance to chemical corrosion; quite stable salt, but can be dissolved in ethers, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons and other organic solvents.
