Product Description
Polyamide Nylon 66 Raw Material Toughened Used for Thermal Break Strips

Product Introduction:

Our PA66GF25 granules is special material for heat insulation profiles. It's extrusion grade modified plastics. It is different from PA66 resin.

Our PA66GF25 granules is reinforced by 25% glass fiber.



1. It has excellent mechanical properties, high strength, high toughness.

2. The material has excellent coloring ability, can achieve various requirements of color matching

3. The shrinkage rate of PA66 is between 1% and 2%. The addition of glass fiber additives can reduce the shrinkage rate to 0.2%~1%. The shrinkage ratio is large in the flow direction and in the direction perpendicular to the flow direction.

4. PA66 is resistant to many solvents, but is less resistant to acids and other chlorinating agents.

5. PA66 excellent flame retardant performance, by adding different flame retardants can achieve different levels of flame retardant effect.
