High flow low odor automotive polypropylene products
The high flow and low odor vehicle polypropylene (PP) product PP EP533N was developed at 300,000 T/A Sphripol twin-ring process unit of Lanzhou Petrochemical Company. The performance of PP EP533N products is comparable to that of similar products by controlling the amount of H2, the content of comonomer and the operation parameters of loop, gas phase reactor, flash line and evaporator. PP EP533N products are applied to instrument panel and automobile door panel, and all the performances meet the requirements of users.
Application scope of polypropylene
Main Applications PP impact copolymer is widely used in the production of industrial products, such as dashboard, auto interior decorations, auto bumpers, interior and exterior parts of washing machine, accumulator containers and tanks. It can also be used to make household articles, such as bottle caps, cookware, furniture, toys, toolkits, travel cases, bags and various packaging containers.
