Well-known PP plastic board excellent corrosion resistance, it is the focus of the public will choose to use objects, and its advantages in addition to its raw materials we need to focus on is that it is a process. Pp plastic plate has good fluidity in melting temperature, good forming performance and the above characteristics of processing technology:

1. The viscosity of PP melt significantly decreases with the increase of shear speed.

2. High molecular orientation and large shrinkage rate.

3, pp plastic processing temperature at about 200-300 ℃, it has good thermal stability, decomposition temperature is 310 ℃, 270-300 ℃, but the heat for a long time to stay in the gun barrel will have the possibility of degradation.

4, because of its viscosity with the increase of shear rate are significantly lower, so improve the injection pressure and injection speed will increase its liquidity, improve the shrinkage deformation and sag, die WenYi control within 30 to 50 ℃.

The shrinkage and crystallinity of pp are lower than that of PE.

The process features of pp plastic board is the characteristics of these in order to realize the value of its products, manufacturers will be in later processing to add color, texture, etc., to attract more users.
