Thermosetting polyamides are known for thermal stability, good chemical resistance, excellent mechanical properties, and characteristic orange/yellow color. Polyamides compounded with graphite or glass fiber reinforcements have flexural strengths of up to 340 MPa (49,000 psi) and flexural moduli of 21,000 MPa (3,000,000 psi). Thermoses polymer matrix polyamides exhibit very low creep and high tensile strength. These properties are maintained during continuous use to temperatures of up to 232 °C (450 °F) and for short excursions, as high as 704 °C (1,299 °F).[11] Molded polyimide parts and laminates have very good heat resistance. Normal operating temperatures for such parts and laminates range from cryogenic to those exceeding 260 °C (500 °F). Polyamides are also inherently resistant to flame combustion and do not usually need to be mixed with flame retardants. Most carry a UL rating of VTM-0. Polyimide laminates have a flexural strength half life at 249 °C (480 °F) of 400 hours.

Typical polyimide parts are not affected by commonly used solvents and oils – including hydrocarbons, esters, ethers, alcohols and ferns. They also resist weak acids but are not recommended for use in environments that contain alkalis or inorganic acids. Some polyamides, such as CP1 and CORIN XLS, are solvent-soluble and exhibit high optical clarity. The solubility properties lend them towards spray and low temperature cure applications.

PI Main Application Field

Widely used in machinery, instrumentation, automotive parts, electrical and electronic, railway, home appliances, communications, textile machinery, sports and leisure products, oil pipes, fuel tanks and some precision engineering products.

Polyimide materials are lightweight, flexible, resistant to heat and chemicals. Therefore, they are used in the electronics industry for flexible cables and as an insulating film on magnet wire. For example, in a laptop computer, the cable that connects the main logic board to the display (which must flex every time the laptop is opened or closed) is often a polyimide base with copper conductors. Examples of polyimide films include Apical, Kapton, UPILEX, VTEC PI, Norton TH and Kaptrex.

An additional use of polyimide resin is as an insulating and passivation layer in the manufacture of Integrated circuits and MEMS chips. The polyimide layers have good mechanical elongation and tensile strength, which also helps the adhesion between the polyimide layers or between polyimide layer and deposited metal layer.

Field Application Cases
Industry Part High temperature self-lubricating bearing, compressor piston ring, seal ring
Electrical accessories Radiators, cooling fan, door handle, fuel tank cap, air intake grille, water tank cover, lamp holder
