Nylon PA66 GF25 Polyamide Granules for Thermal Barrier Strips Used in Aluminum System Window
Product Introduction:
-Nylon/PA66 granules reinforced by fiberglass. The performance of final products of this raw material were in line with the national standard.
-The product is based on PA66 resin as basic, add glass fiber, efficient flame retardants and various additives, formed by twin-screw extrusion blending.
Advantage:
- High mechanical strength
- High toughness
- High softening point
- Good wear resistance
- Self-lubrication
- Long-term work at higher temperatures
- It has high CTI value , excellent electrical insulation, low smoke and low toxicity characteristics.
