Product Descriptions：

Polypropylene is a synthetic resin made by polymerization of propylene (CH3-CH=CH2) with H2 as the molecular weight modi-fier. There are three stereomers of PP-isotactic, atactic and syndiotactic.

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. It is 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 165℃. It has high tensile strength, surface hardness and good environmental stress crack resistance. It can withstand 120℃ continuously.
