US compounder of engineering resins Polymer Resources has debuted its new unfilled, impact-modified polybutylene terephthalate (PBT) resin.
The injection-molding-grade TP-FR-IM3 resin is intended for such electrical applications as outdoor, intermittent-outdoor, and indoor components like enclosures and housings.
The company says it offers high levels of weatherability, chemical and impact resistance, and flame retardance, earning all-color certification under UL743C F1. It meets the UL94 V0 and UL94 5VA standards for flame retardance at 1.5 mm (0.06 inches) and offers high impact resistance, high electrical resistance, high dielectric strength and low dielectric loss.
“We developed a robust PBT material that is ideal for demanding outdoor environments,” said Bill Galla, Vice President of Sales, Polymer Resources. “This new grade checks all the boxes, from UL F1 all-color certification for outdoor suitability, to outstanding resistance to lawn and garden, automotive and cleaning chemicals.”
