PP is a crystalline polymer. Among the commonly used plastics, PP is the lightest with a density of only 0.91g/cm3 (smaller than water).Among the general plastics, PP has the best heat resistance. Its thermal deformation temperature is 80-100℃ and it can be boiled in boiling water.PP has good stress cracking resistance and high bending fatigue life.The comprehensive performance of PP is better than that of PE material.PP products are light in quality, good toughness, good chemical resistance.In daily life, good quality crisper is made of PP material.
