Product Description:
Polyamide 6.6 granules reinforced by fiberglass, with special additives, is blended and extruded by twin screw extrusion machine. It is more suitable for extrusion of heat insulation strip. Compared with ordinary granules, it is more conducive to forming. It has certain advantages in speed, surface finish and yield. The performances of nylon insulating strip produced made of this material meet the national standards. It can not only be customized according to customer requirements, far exceeding the national standard, but also can add high-efficiency flame retardant to achieve the purpose of flame retardant.
PA66 Features
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.
Introduction of Our PA66GF25 Granules:
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.
Application:
Specially used in thermal break strips, thermal bridge, heat insulation bar, etc.
