Polybutylene Terephthalate (PBT)
The VALOX family of thermoplastic polyester resins are semi-crystalline materials based on polybutylene terephthalate (PBT) and/or polyethylene terephthalate (PET) polymers. VALOX resin formulations include many performance-matched grades designed to provide application-specific property profiles. VALOX resins combine heat and chemical resistance, as well as outstanding electrical properties with exceptionally good processability and surface appearance.
TAILORABLE PROPERTIES High mechanical, thermal and electrical properties combined with excellent chemical resistance and dimensional stability
EXCELLENT CHEMICAL RESISTANCE Excellent resistance to a variety of chemicals, including hydrocarbons, dilute acids and bases, detergents, and most aqueous salt solutions
VERSATILITY AND REGULATORY COMPLIANCE Available in a broad range of both filled and unfilled grades, with specified UL and other agency compliance ratings. Healthcare grades meet food contact and medical regulatory specifications.
FLAME RETARDANCY Flame retardant grades offer a UL94 5VA rating and a glow wire test (GWT) pass at 960 °C
GOOD TEMPERATURE PERFORMANCE Relative temperature index (RTI) up to 284 °F (140 °C), yet provide good low temperature performance to -40°F (-40°C)
VERY GOOD PROCESSABILITY High flow in thin sections, offering excellent surface finish
