PP plastic stool surface with those raw materials, what is the ratio?
PP has good stress cracking resistance and has a high bending fatigue life, commonly known as "fold gum"".The comprehensive performance of PP is better than that of PE.
In general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100 DEG C and can be boiled in boiling water.
PP is crystalline polymer. PP is the most common plastic, and the density is only 0.91g/cm3 (smaller than water).
