PPA plastic Chinese: high temperature resistant nylon PPa heat distortion temperature up to 300 ° C or more, continuous use temperature up to 170 ° C can meet your short-term and long-term thermal performance. It maintains its superior mechanical properties - strength, hardness, fatigue resistance and creep resistance - over a wide temperature range and in high humidity environments. Toughened grade PPA combines superior toughness with a range of hardness and flexibility, and requires a one-time rigidity in fasteners and a good choice for flexibility in repetitive use.
The PPA resin containing 45% glass short fiber has a tensile strength of about 276 MPa, a flexural modulus of more than 13,786 MPa, and a heat distortion temperature of HDT 549 °F. Even with mineral filler grade PPA, the tensile strength can reach 117 MPa. PPA resins are less ductile than nylon 6, however unreinforced impact modified grade PPA resins have been developed with a notched Izod impact strength of up to 20 ft-lbs. PPA materials combine excellent productivity with fluidity during molding, and have excellent strength, toughness and dimensional stability in temperature rise, heavy structural loads, high humidity, corrosive chemicals, including automotive fuels and other automotive fluids.
