PAI pellets
PAI is a family of soluble polyamide-imides sold in pellets form. The polymer is tough, chemically resistant, and thermally stable. It has thermal capability similar to many polyimides, at a lower price. Coatings based on AI polymers have been shown to be cost-effective in electrical/electronic, high-temperature decorative, and corrosion prevention applications.
PAI is available in water-soluble versions that possess exceptional mechanical, thermal, chemical resistance as well as wear-resistant properties.
Torlon resins are inherently non-flammable, have outstanding electrical properties, and possess enormous temperature stability from cryogenic to 300°C and some grades are FDA compliant.
