Customized Modified Virgin PA66 Polyamide Nylon 66 For Heat Insulation Profiles
Customized Color Modified or Virgin PA6 PA66 Polyamide Nylon 66 For Produce Heat Insulation Profiles
Introduction of Raw Material:
PA has the advantages of high mechanical strength, high softening point, good wear resistance, self-lubrication, cushioning, sound deadening, excellent oil and chemical corrosion resistance, and good electrical insulation. Because of these superior performance, PA composite have already replaced some metals being as structural materials.
Product Description:
-PA66GF25 granules are reinforced by fiberglass. The final product performance of this raw material can meet the national standard.
-TPA66GF25 granules are based on PA66 resin. Then the granules are formed by twin-screw extrusion machine after adding fiberglass, efficient flame retardants and various additives.
