| Description Non-flammable PP FB51 and FB51R, which are designed with base resin that has excellent shock resistance, exhibit high shock resistance. In particular, its excellent fluidity allows good formability and nice exterior with high non-flammability so to be Widely used for exterior of electric/electronic parts. Characteristics FB51R: As non-flammability grade of UL94 V-2, it provides long-term thermal stability as Well as excellent shock resistance in low temperature (-20°C ). Thus, it keeps high shock resistance regardless ofuse circumstance, even in Winter. It is Widely used for exterior of heat transmission/electric/electronic products like a fan heater. Applications Fan heater exterior (FB51, FB51R) Other electric/electronic parts needing shock resistance and non-flammability (FB51, FB51R)&& |
