Polybutylene Terephthalate Exablend PBT W3100
Description
A PBT-based compound. Heat-stabilized, hydrolysis-resistant, light-stabilized and UV-stabilized. Bright white color.
A well-balanced material with excellent gloss, low moisture absorption and stable properties under a variety of environmental conditions.
Advantages
- bright white color
- higher strength than ABS plastic
- no warpage and dimensional stability
- low price
- a circular economy product with minimal CO2 emissions
Applications
A material with a wide range of applications. Its benchmark white brightness, unattainable for polyamide and ABS plastic, makes Exablend W3100 suitable for molding high-quality hardware. It can be used instead of polyamide as a more modern replacement and does not cause warpage or sink marks thanks to its shrinkage anisotropy.
