3.Low Fume、Non-inflammable、High temperature resistance，High temperature mechanical strength higher than PTFE and F46 | ||
F46 | 1.Chemical stability, electrical insulation, lubricity, non stickiness and flammability are similar to PTFE，But, F46 material showed better strength, aging and temperature resistance than PTFE | 1.Long-term use temperature resistance ≤110℃ |
2.Good adhesion to metal,Wear resistance better than PTFE | 2.Can be used to measure most strong corrosive media such as strong acids, strong bases, strong oxidizing agents。But not for KOH, nitric acid, hydrofluoric acid, etc | |
3.With excellent tear resistance properties | ||
Chloroprene Rubber (CR) | 1.Excellent elasticity and wear resistance | 1.Temperature resistance≤65℃ |
2.Resistance to corrosion of generally low concentration acid, base, and salt media, intolerance to corrosion of oxidation resistant media | 2.Measurement of general water, sewage, mud, mineral pulp | |
polyurethane rubber （UR) | 1.There is an excellent wear resistance performance, and a good oil resistance | 1.Long-term use temperature resistance ≤60℃ |
2.The strength is high and tear resistance is good, but the acid resistance and alkaline energy are poor |
