|---|
| TB72W is a super weatherability and heat-resistant polypropylene compound 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. This product is made with a variety of base PP, such as HIPP (High Isotactic Polypropylene). In addition to the characteristics noted above TB72W exhibits excellent impact-resistance, long-term heat-resistance, resistance to thermo-discoloration, anti-static property, and dimensional stability.&& |
