The strength of New Car plastic products increases with the increase of

Copolymer PP materials have lower heat distortion temperature, low transparency, low gloss, and low rigidity, but have stronger impact strength.

The strength of New Car plastic products increases with the increase of ethylene content. Due to the high crystallinity, the surface stiffness and scratch resistance of this material are very good.
PP does not have the problem of environmental stress cracking. Usually, PP is modified by adding glass fiber, metal additives or thermoplastic rubber.
For materials with the same MFR, the strength of copolymer type is higher than that of homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high.
And the directional uniformity of shrinkage is much better than that of materials such as PE-HD. These special processing steps have increased the performance of Fuel Car plastic products to varying degrees.
