PAI - Polyamide-imide
Crystalline polymer. Material with high mechanical and thermal properties
(up to 260°C.). It resists to creep under load and to wear, its friction
coefficient is low.
FEATURES
- high temperature. It resists beyond 250°C. Dimensional stability
- high E-modulus
- good abrasion resistance and low friction coefficient
- flame resistance (V.0)
WEAK POINT
- very high cost
- the machining is difficult
APPLICATION
- mechanical: the dimensional stability at temperature
is high, as well as the heat resistance. Components obtained by PAI
have a very high wear resistance and are self-lubricating. It is used
to produce high performance pieces at low as well as at high temperatures:
bearings, cams, precision gears, etc.
- electrical: very good dielectric and insulating properties
- chemical: very good chemical resistance
- food contact: it is not used in contact with food
