PP contains no polar groups and has excellent electrical insulation properties. Its water absorption rate is less than 0.01%. PP is a semi-crystalline polymer with good chemical stability. Itis stable to most chemical except strong oxidizers. Inorganic acid, alkali and salt solutions have almost no damaging effect on PP.
PP has good heat resistance and low density. Its melting point is at around 165â??. It has high tensile strength and surface hardness and good environmental stress crack resistance.It can withstand 120â?? continuously.
Sinopec is the largest PP producer in China,Its PP capacity accounted for 45% of the country's total capacity. The company currently has 29 PP plants by the continuous process (including those under construction)
PP Application
