Frost-resistant glass-filled polyamide Examid PA6 GF30 HI
Description
A highly reliable glass-filled polyamide 6, improved in every respect. Excellent processability and strength make it possible to mold high-quality parts free of internal stresses. High shrinkage isotropy, resistance to creep and warpage. The material is frost-resistant and retains impact resistance at low temperatures.
Advantages
- high strength at sub-zero temperatures
- withstands -60 °C
- withstands millions of alternating-load cycles
- excellent mold-filling behavior
- accurate part dimensions
Applications
Well proven in critical mechanical-engineering parts with tight tolerance grades, in transport and in electronics. Its chemical resistance has enabled use in the oil-refining industry. It can also be used for molding sporting goods, tool housings and furniture components, providing excellent moldability, fine appearance and superior strength.
