Hanwha Total PP SI83R

About
Description High-gloss compound PP SI83R is specially processed for high-flowability and low deformation. Hanwha Total has resulted in impressively improved grades that are far superior to the low gloss, low productivity and high-warp characteristics extant in other brands. These grades are also designed for application on exterior parts of large home appliances, such as rectangular rice cooker housings. Characteristics High-gloss compound PP SI83R grades contain high crystalline PP (HIPP, High Isotactic Polypropylene) basic resin, promising better heat-resistance and rigidity; and improving thermal strain-resistance when used in electric heating equipment. These grades have improved flowability. We have accomplished this by adjusting the oil-modified characteristics of high polymers to minimize residual stress during melting and solidification. This has solved the warp problem in molded products by optimizing the shrinkage ratio between the machine direction (MD) and transverse direction (TD) during injection molding. Applications Rectangular rice cooker housings (bodies, bases, and covers) Bread makers Exterior parts of electronic products which require high flowability, heat resistance, glossiness and low-weld effects.&&
