Toray TORAYCON™ PBT Resin 1101G-X08 Polybutylene Terephthalate (PBT), 35% GF + GB
Categories: Polymer; Thermoplastic; Polyester, TP; Polybutylene Terephthalate (PBT)

Material Notes: Reinforced, low warpage, (GF+GB)35%, PBT+P-(GF+GB)35.

General Toraycon™ Notes: TORAYCON™ PBT (polybutylene terephthalate) is a polyester-based thermoplastic engineering plastic with excellent electrical properties and chemical resistance. PBT resin is produced from the primary starting materials 1,4-butanediol and terephthalic acid and is a linear thermoplastic saturated polyester resin with ester bonds in the main chain. Unique features can be easily provided by compounding various additives, glass fibers, flame retardants, and utilizing solubilizing techniques. Furthermore, it is easy to add any color. The product is used in a large number of applications spanning several fields, including electrical and electronic devices, connectors and capacitor casing, automotive electronics, OA equipment, building materials, and industrial machinery parts.
