PVC PVC lining wear sheave block

PVC lining sheave block details are as follows: Polyvinyl chloride (PVC) with a flame retardant (flame retardant is over 40), high chemical resistance, mechanical strength and good electrical insulation advantages. PVC has a stable physical and chemical properties, insoluble in water, alcohol, gasoline, gas, vapor leakage is low; at room temperature, can be resistant to any concentration of hydrochloric acid, sulfuric acid below 90%, 50-60% of nitric acid and 20% The caustic soda solution, with a certain chemical resistance; for salts fairly stable, but can be dissolved in ethers, ketones, chlorinated aliphatic and aromatic hydrocarbons and other organic solvents. Made with PVC sheave, guide wheel pad with the following features: 1. Good flame resistance; 3 high mechanical strength;; 2. Excellent chemical resistance 4. Good stability; electrical insulation sex.
