ppa gf30 plastic price sell best long glass fiber ppa lgf30 granules

The semi-crystalline PPA is a material used for injection molding. It has a melting point of about 590°F and is supplied in the form of opaque rectangular slices. PPA resins are stronger and harder than fatty polyamides such as nylon 6, 6, etc.; less sensitive to moisture; better thermal performance; and creep, fatigue and chemical resistance are much better. For example: PPA resin with 45% glass short fiber, tensile strength is about 276MPa, flexural modulus exceeds 13786MPa, heat distortion temperature (HDT) 549°F. Even with mineral filler grade PPA, the tensile strength can reach 117MPa.

PPA has higher thermal stability than PA46, better CTI arc resistance and infrared reflow capability. PPA has excellent resistance to various oils such as gasoline, diesel, engine oil, mineral oil, transformer oil, etc., even at high temperatures of 150°C. Even under extreme weather conditions such as high ultraviolet radiation, high humidity, and high temperature, PPA is suitable for long-term outdoor use without causing physical properties to be reduced.
