Syensqo (Solvay Specialty Polymers) Torlon® 4203 Polyamide-imide (PAI) (discontinued **)
Categories:	Polymer; Thermoplastic; Polyamide-imide (PAI); Polyamide-Imide, Extruded
Material Notes:	Torlon 4203 is an unreinforced, lubricated, pigmented grade of polyamide-imide (PAI) resin for extrusion. It has the best impact resistance and greatest elongation of all the Torlon grades. Torlon PAI has the highest strength and stiffness of any thermoplastic up to 275°C (525°F). It has outstanding resistance to wear, creep, and chemicals. Torlon 4203 offers outstanding electrical properties, which makes it ideal for high performance parts such as connectors, switches and relays. In addition Torlon 4203 polyamide-imide can be used in applications such as thrust washers, spline liners, valve seats, bushings, bearings, wear rings, cams and other applications requiring strength at high temperature and resistance to wear. - High Flow: Torlon 4203 EXT - Higher Flow: Torlon 4203 HQ - Highest Flow: Torlon 4203 HHQ Information provided by Solvay Specialty Polymers.
Vendors:	Drake extrudes shapes and machines and injection molds parts in Torlon® PAI, PEEK, PAEK, Ryton PPS and Ultem PEI. It also machines Vespel® PI. Innovations include cryogenic CryoDyn® CT-200 shapes as a PCTFE alternative; efficient Seamless Tube® and the largest extruded rod diameters to >254mm and plate thicknesses to > 100mm.
