Polyamidimide / PAI rods

Polyamidimide rods have a very high mechanical strength and hardness at low temperatures and very high stability temperature of the mold. The PAI glass transition temperature (+ 280 ° C) of the polymer is higher than the short operating temperature (+ 250 ° C) which means that the polymer will not change its properties even at the highest possible operating temperature, and the parts made of PAI rods will flawlessly work even under excessive heat.

The low coefficient of thermal expansion and low creep, high chemical resistance, low ability to fire did Polyamidimide rods demanded in many areas as the best solution to complex problems, as well as metal replacement, titanium, asbestos, Kevlar, fiberglass impregnated with phenol-formaldehyde, Teflon, PEEK.
 
 
The polyamide-imide is resistant to UV, gamma, and X-rays. Polyamidimide rods may briefly operate at a temperature of over 270 ° C. The polymer has a high toughness both at high positive temperatures and cryogenic conditions.
 
Thanks to the combination of a wide variety of properties and the ability to carry large mechanical stress in extreme conditions, this polymer is widely used in almost all high-tech areas of production: from Space to instrumentation. Polyamidimide is supplied in diameter rods from 10 mm to 300mm
 
 
Applications:
Connectors, switches, relays, thrust washers, spline liners, valve seats, check balls, poppets, mechanical linkages, bushings, wear rings, Insulators, cams, picker fingers, ball bearings, rollers, and thermal insulators.
