The advantages of the PP material

1. (PP toilet seat）High hardness and high melting point
2. （PP toilet seat)Low heat distortion temperature (100 ℃), low transparency, low gloss and low rigidity

3. (PP toilet seat)The impact strength is high, and the strength of PP increases with the increase of ethylene content
4. The surface stiffness and scratch resistance are good. PP board is modified by adding glass fiber, metal additive or thermoplastic rubber. The flow rate MFR range is 1 ~ 40. PP material with low MFR has good impact resistance but low tensile strength. Therefore, there is no environmental stress cracking problem in PP plate.
5. The shrinkage of PP board is quite high. The shrinkage of PP plate is generally 1.8 ~ 2.5% because it is a semi crystalline material. And the directional uniformity of shrinkage is much better than that of PE-HD and other materials.
6. It has excellent moisture absorption resistance, acid-base corrosion resistance and solubility resistance.
