PBT Impact Resistance

- January 01, 2016 -

Elvaloy® enhances impact strength while maintaining other properties needed in electrical and electronic connectors, as well as a wide range of other industrial and consumer products.

Elvaloy® PTW provides super-tough impact resistance while improving hydrolysis resistance of PBT compounds for higher product quality. It also can enable increased productivity, while achieving improved impact strength in cast PET-based sheet applications.

For the most demanding PBT impact resistance requirements, Elvaloy® PTW provides super-toughness in virgin and glass fiber reinforced compounds.

Dow™ Elvaloy® PTW terpolymers and Elvaloy® AC acrylate copolymers enhance PBT and PET resins as an impact modifier, nucleating agent, processing aid to improve melt flow, and as a hydrolysis stabilizer. Examples of Dowpolymer modifiers used in polyester include the following:
