High reputation PP Yarn Grade - PP resin – Junhai
High reputation PP Yarn Grade - PP resin – Junhai Detail:
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.
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). Technologies used by these units include Mitsui Chemical’s HYPOL process, Amoco’s gas phase process, Basell’s Spheripol and Spherizone process and Novolen’s gas phase process. With its strong scientific research capability, Sinopec has independently developed a second-generation loopprocess for PP production.
PP Features
1.The relative density is small, only 0.89-0.91, which is one of the lightest varieties in plastics.
2.good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding processing performance is good.
3.It has high heat resistance and the continuous use temperature can reach 110-120 °C.
4.good chemical properties, almost no water absorption, and does not react with most chemicals.
5.the texture is pure, non-toxic.
6.electrical insulation is good.
