Glass-Filled Polybutylene Terephthalate Exablend PBT GF20 B3090
Description
20% glass-filled PBT: heat-stabilized, hydrolysis-resistant, light-stabilized, UV-stabilized. Black color.
A well-balanced material with excellent surface quality, high stiffness and dimensional stability. Low moisture absorption and stable properties under various environmental conditions. High dielectric strength.
Key properties
- weather and UV resistance
- excellent appearance
- high strength values
Applications
Recommended for molding parts that require dimensional stability under temperature swings and varying humidity. Unlike polyamides, it does not lose tensile or compressive modulus when saturated with moisture. Recommended for the production of electrical components.
