Products Introduction

Polypropylene is a synthetic resin made by polymerization of propylene (CH3—CH=CH2) with H2 as the molecular weight modifier. 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 and surface hardness and good environmental stress crack resistance. It can withstand 120℃ continuously.

Products Application

PP has a variety of applications. It is suitable for multiple processing methods such as injection molding, extrusion molding and blow molding and is widely used in the textile, packaging, electrical household appliances, automobile and real estate industries. SINOSAB   PP plants have varied technologies to produce homopolymer, random copolymer and impact copolymer PP with distinct properties. These products include BOPP film, CPP film,fiber, pipe, coating, yarn,injection-molding products.
