What is the hard plastic material?
PPS is one of the best heat resistant varieties in engineering plastics. The thermal deformation temperature is generally greater than 260 degrees. The chemical resistance is only inferior to that of polytetrafluoroethylene, and the fluidity is only inferior to that of nylon. In addition, the utility model has the advantages of small shrinkage rate (about 0.08%), low water absorption rate (about 0.02%), good fire resistance, shock resistance, good fatigue, etc..
PPS, the Chinese name is pps. The utility model has the advantages of hard and crisp, high crystallinity, burning resistance, good thermal stability, high mechanical strength, good electrical performance, etc..
The hard plastic, of course PPS is relatively hard, but it also has many disadvantages, such as the production of something very brittle, brittle, and the friction coefficient greatly, is generally not used for wear-resistant products, can only be used for structural parts.At present, the hard and wear-resistant is Parmax, this plastic friction coefficient is low, suitable for heavy load and other wear-resistant parts, POLYMSJ gives the conclusion that the wear resistance is excellent in plastics at present. It is also available in the country.
