Sabic has extended its range of Extem thermoplastic polyimide (TPI) resins with a new grade that can withstand temperatures of up to 260°C.
Extem UH resin is designed for automotive, aerospace, semiconductor, electrical and chemical applications and has a better mechanical performance thank PEEK, says Sabic. The material can be used as a metal replacement in applications where no previous resins were available and is cheaper to use than PAI, adds the firm. The new Extem UH 1019 resin has a continuous-use temperature rating of 260°C and offers eight times better stiffness than PEEK, meaning it can be used for thin walls and complex shapes with high dimensional stability, says Sabic. The material can be injection moulded or extruded and is recyclable.
