The main raw material of the PP hollow board is polypropylene. In order to make the pp hollow board have more performance, the filler is often added to the hollow board. The commonly used fillers are stone powder, mica, glass fiber, etc. What is the specific effect?



1, mica
The molded product of the hollow plate not only has a large improvement in mechanical properties, thermal properties, and electrical insulation properties, but also has high elastic modulus and good structural dimensional stability. The amount of mica added to the filled polypropylene is generally controlled at about 40%.

2, fiberglass
The tensile strength and flexural strength of the hollow board product are higher than those of the molded product after the addition of the other filler to the polypropylene.

3, talcum powder
The product of pp hollow board has good heat resistance, stable structural size and high hardness. The filled polypropylene product with higher content of filler has better heat resistance, cold resistance, mechanical properties and processability than pure poly. Acrylic products.

The amount of talc added to the polypropylene is generally controlled at 20% to 40%. However, it should be noted that the tensile yield strength of these two materials will gradually decrease as the ratio increases.
