Tips: What are the characteristics of the four different linings – chloroprene, polyurethane, JPEFE and F46?
| Material | Main Characteristics | Maximum Operating Temperature | Applications |
| Neoprene | Excellent elasticity, high tensile strength, good wear resistance. Resistant to general low-concentration acids, alkalis, salts, and oxidation. | 80°C (Custom orders can reach 120°C) | Suitable for water, sewage, weakly abrasive slurries, and mining slurries. |
| Polyurethane | Excellent abrasion resistance, but relatively poor resistance to acid, alkali, and salt. | 70°C | Suitable for medium-strong abrasive slurries, coal, and mud. |
| JPEFE | Resists almost all chemicals, including sulfuric acid, hydrochloric acid, and oils. Suitable for high-temperature and high-speed fluids. | 100°C | Suitable for corrosive chemicals and fluids in various industrial applications. |
| F46 | Excellent resistance to oxidation and high-pressure resistance. | 150°C (Custom orders can reach 150°C) | Primarily used in sanitary applications and for chemical fluids requiring high resistance. |
