| Abstract: | The effects or the mold temperature and the injection pressure on the microstructure, the tensile strength and fracture morphology or polypropylene plaques have beenstudied. It is shown that the effects of the mold temperature and the injection pressure onthe density. Crystallinity, skin thickness, the degree or orientation and tensile strength arelarger than the effects an the tensile fracture morphology. |
