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.
Characteristic:
Its characteristics are high mechanical strength, large modulus, good wear resistance, stable size and long-term work at high temperature.
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.
