The market has two kinds of makings to make mostly, more mature product is multi-purpose PE is made. For example, do a better fuguang brand ceramic tile locator is made of new materials with environmentally friendly high-density PE, the color is white through, its advantages are good toughness, good tension, non-toxic, impact resistance, moisture resistance, resistance, not easy to explode. Features: corrosion resistance, excellent electrical insulation (especially high frequency insulation), chlorination, chemical crosslinking, irradiation crosslinking modification, glass fiber reinforcement.
Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance (the lowest temperature can reach 70 ~ 100 ℃), chemical stability is good, most of acid and alkali erosion (acid) with characteristics of oxidation resistance, temperature does not dissolve in solvents, small water imbibition, good electrical insulation performance.
The strength of PP increases with the increase of ethylene content. PP vicat softening temperature is 150 ℃. Due to high crystallinity, the surface stiffness and scratch resistance of this material is very good. There is no environmental stress cracking problem in PP. In general, PP is modified by adding glass fiber, metal additives or thermoplastic rubber.
