PAI[Torlon series, Toray-TI series]

Material characteristics

PAI is a noncrystalline resin. It is a kind of polyamide with excellent heat resistance and mechanical strength, and polyamide with good processability and toughness. The characteristics of heat resistance (continuous use temperature of 250 DEG C), high heat deformation (bending load temperature of 279 DEG C), mechanical properties (especially high tensile strength and impact resistance), fatigue resistance, flame resistance, friction and wear characteristics of high pressure resistance, excellent rupture.
