TECAPAI® CM XP403 green

​Unreinforced polyamide-imide (PAI)

TECAPAI CM XP403 green is a compression molded Torlon® plastic material that is unreinforced and delivers an excellent combination of physical properties. Made from Solvay Torlon® powder, this PAI material offers excellent ductility and toughness as well as good strength and stiffness at elevated temperatures. Additional characteristics include good dielectric properties, wear performance, and excellent chemical resistance in its staple, which is typical of polyamide-imide properties. Users will find this PAI polymer extremely useful in applications such as electrical connectors, wear components and large parts that require strength and stiffness. Because it is compression molded, TECAPAI CM XP403 green can be ordered by the piece, adding to its usefulness and versatility. TECAPAI CM XP403 green is Ensinger's version of a product commonly referred to in web searches as "torlon 4503".
