PA12 GB (glass beads)
A stiffer, dimensionally stable nylon; parts that hold their size at high temperatures.
What is PA12 GB (glass beads)?
PA12 GB is PA12 filled with about 40% glass beads. Stiffness and dimensional stability increase while elongation decreases. It suits enclosures, fixtures and parts that must hold their dimensions when hot.
- High strength
- Heat resistant
