While Kixx is an acknowledged name in gasoline and lubricants, Hiprene is GS Caltex’s polypropylene product that enjoys the same distinction. GS Caltex produces and supplies the high quality polypropylene, Hiprene, employing the Unipol process of fluidized bed-based vapor-phase polymerization.

Polypropylene (PP) is made by polymerizing propylene, the feedstock, in the presence of a catalyst. Due to easy processing and its heat-resistant and crystalline properties, propylene is used in a wide range of applications including film, pipes, various molded products, electronic goods and automotive components.

Depending on the orderly arrangement, polymerization leads to the formation of isotactic, syndiotactic and atactic polypropylene. Isotactic propylene has good crystalline, mechanical and thermal properties and is widely used in commercial applications. In general, PP compounds are isotactic.

PP Compound

PP compounds are made by adding other polymers such as inorganic fillers and rubber, as well as functional additives such as flame retardants and nucleating agents, to homo polymer, random polymer and impact polymer. PP compounds possess greatly enhanced properties over conventional polypropylene.

There are many grades of PP compounds according to purpose and properties such as rigidity, conductivity, thermal resistance, glossiness, softness, paintability, and flame retardation. PP compounds are widely used in making interior and exterior materials for automobiles and electric appliance parts. As the first company in Korea to develop PP compounds and LFT materials with outstanding paintability, GS Caltex has gained recognition for its technological prowess.
