Overview Of PAI Material

PAI plastic-imide (PAI) is a new variety developed in 1964 by the Amoco Institute in Napervill, Illinois.

In 1965, the insulation paint was trial-produced. Later, ultra-high-performance engineering plastics were developed. It was launched in 1971 under the trade name TORLON. It was originally produced in Joliet, Illinois. In 1986, Amoco Performance Products was established. Greenvill, South Carolina expansion. The advent of PAI solves the technical problem that polyimide could not be injection molded in the past. Various precision shapes of complex products can be formed by injection technology, and the production efficiency is also significantly improved. Moreover, PAI has good heat resistance, tensile, bending, compressive strength, dimensional stability, and abrasion resistance are better than other engineering plastics.

Polyamide Imide is usually formed by polycondensation of phenyltricarboxylic anhydride and diisocyanate in DMF solution. PAI (polyamide-imide) is a new type of engineering plastic containing amide groups. Due to the very stable aromatic heterocyclic structure in the polyimide molecule, it exhibits heat resistance and low temperature resistance unmatched by other polymer materials.PAI Machining  has excellent mechanical properties and dimensional stability under high temperature environments. .

Characteristics Of PAI Material

The allowable working temperature in the air is very high, it has the best dimensional stability in the temperature range of 250 ℃, excellent abrasion and friction performance, outstanding UV resistance, superior high energy radiation resistance, and inherently low flammability. High strength, high insulation, radiation resistance, corrosion resistance, self-lubrication, and small thermal expansion coefficient.

Application Of PAI Material

Commonly used in the production of precision cnc machining parts for high-tech equipment, and occasions with extremely high wear resistance, such as non-lubricated bearings, seals, bearing isolation rings and reciprocating compressor parts, electronics and semiconductor industry. Products for high-temperature, high-vacuum, strong radiation, and ultra-low temperature conditions. Molded products are used as aircraft parts, reciprocating compressor impellers, bearing isolation rings, jet engine fueling system parts; chipset and socket, cup body welding support ; For making precision parts, such as electronics and semiconductor industry, oil drilling equipment, etc.
