Plastic PPT30S add what material will increase hardness?
Commonly used talc and calcium carbonate increase the flexural modulus rather than the surface hardness. To increase surface hardness, a nucleating agent can be used. Moreover, talc and calcium carbonate can not be added to the injection molding, you must use the pumping equipment.
In general, this material will be grafted with PP-G, POE, increase the impact, plus stone powder, glass fiber, mica powder, increase hardness.
