Polyamide-imide is a kind of modified polyimide. It is an amorphous high temperature resistant thermoplastic engineering plastic. It is mainly obtained through the condensation of trimellitic anhydride and various aromatic diamines.
The main features:
High temperature resistance: Allows very high working temperatures in air (continuous operation at 250°C).
Good dimensional stability: Best dimensional stability in the 250°C temperature range.
High strength: The strength is unmatched by any industrial unreinforced plastic in the world today.
Excellent wear and friction properties.
Outstanding UV resistance.
Excellent resistance to high-energy radiation (γ-rays and helium rays).
Inherently low flammability.
Good adhesion, flexibility and alkali resistance.
Good electrical insulation.
Mainly used in IC test equipment / chips, high-speed bearings, power equipment, high temperature gear, mold parts, food machinery, electronic and semi-body industries, space appliances and other demanding areas.
It is commonly used in the manufacture of precision parts for high-tech equipment, as well as for applications where wear resistance is extremely high, such as non-lubricated bearings, seals, bearing isolation rings and reciprocating compressor parts, electronic and semi-conductor industries.
For high temperature, high vacuum, strong radiation, ultra-low temperature conditions of work products. Molded plastics are mainly used for gears, rollers, bearings and copier separation claws.
It has good ablation resistance and high-temperature, high-frequency electromagnetic properties, and can be used as ablation materials, magnetic permeability materials, and structural materials for aircrafts.
Can also be used as aircraft parts, reciprocating compressor impeller, bearing isolation ring, jet engine combustion system parts; chipset and socket, cup body welded bearing.
For the production of precision parts, such as electronics and semiconductor industries, oil drilling equipment.
