| Description Super-heat-resistant PP compound exhibits significantly improved strength and heat-resistance due to the addition of the inorganic filler, talc to mo-polypropylene. These products employ a variety ofbase PPs, such as HIPP (High Isotactic or High crystalline Polypropylene), and are manufactured with Hanwha Total’sspecial processing technology to ensure quality. Superior rigidity, long-term heat resistance, anti-static property, and dimensional stability are characteristic of these products. super-heat-resistant PP compound is Widely used in electric and electronic products that are subject to high temperatures. Characteristics The addition of talc to high stereospecific polypropylene offers super heat-resistance and dimensional stability; Superior strength; Excellent processability; Outstanding long-term heat-resistance to static electricity, steam discoloration and high-temperature immersion. Applications Electric and electronic parts subject to high temperatures; -Inner lids of electric rice cookers.&& |
