| Description Super weatherability and heat-resistant compound PP are ideally suited for use in air-conditioner exterior parts and other outdoor purposes. We have significantly improved strength and heat-resistance by adding talc, the inorganic filler, to polypropylene. These products are made with a variety of base PP, such as HIPP (High Isotactic Polypropylene), providing our customers with the best quality products of their kind on the market. In addition to the characteristics noted above, Hanwha Total’s super weatherability, heat-resistant compound PP exhibit excellent impact-resistance, long-term heat-resistance, resistance to thermo-discoloration and anti-static property, and dimensional stability. Characteristics Excellent weatherability: TB52U has received certification for environmental exposure, meeting the UL746C F1 and UL484 standards, High heat-resistance and dimensional stability;. Superior rigidity and impact-resistance; Superior processability. Applications Outdoor electric and electronic parts such as air-conditioner exterior parts (housing, side covers, grills, top plates , etc.). Outdoor industrial use such as transport containers.&& |
