Lining materialMain performanceApplications

1. It is the material that has most stable chemical property among plastics:

resistant to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, also resistant to concentrated alkali and various organic solvents, not resistant to

corrosion by chlorine trifluoride, high temperature oxygen trifluoride, high flow

rate liquid fluorine, liquid oxygen and ozone.

2. Poor wear resistance.

3. The ability to resist negative pressure is poor.

1. 100°C, 150°C (special customization)

2. Strong corrosive media such as concentrated acid 

and alkali.

3. Hygienic media.

PCR(Polychloroprene Rubber)

1. It has excellent elasticity, high breaking force and good wear resistance.

2. It is resistant to the corrosion of general low-concentration acid and alkali salt media, and not resistant to the corrosion of oxidative media.

1. 80°C, 120*C (special customization)

2. General water, sewage, weak abrasive mud, ore pulp.

PUR (Polyurethane)1. Excellent wear resistance (equivalent to ten times that of natural rubber).

2. Acid and alkali resistance is poor.

3. It cannot be used for water mixed with organic solvents.

1. < 80°C

2. Neutral and strong abrasive slurry, coal slurry, mud, etc
