PTFE
Main performance: It is the most stable chemical property in plastics. It can resist boiling hydrogen chloride, sulfuric acid, nitric acid and aqua regia. It can also resist concentrated alkali and various organic solvents. It is not resistant to chlorine trifluoride and high temperature chlorine trifluoride. High flow rate of liquid fluorine, liquid oxygen, self-oxygen corrosion; poor resistance to bismuth; poor resistance to negative pressure.
Scope of application: 1.100 degrees, 150 degrees (special order); 2. Strong corrosive medium such as concentrated acid, alkali; Hygienic media.
Polychloroprene
Main performance: Excellent elasticity, high tearing force and good wear resistance. It is resistant to corrosion of general low concentration acid, alkali and salt media, and is not resistant to corrosion by oxidizing media.
Scope of application: 1.80 degrees, 120 degrees (special order); 2. General water, sewage, weak mud slurry.
Polyurethane rubber
Main properties: Excellent wear resistance (ten ten times that of natural rubber); poor acid and alkali resistance; can not be used for water mixed with organic solvents.
Scope of application: 1. Less than 80 degrees; 2. Neutral strong wear of pulp, coal slurry, mud.
