描述
Zytel 70G43HSLA BK099 PA66 is a 43% glass fiber reinforced, heat stabilized black polyamide 66 resin designed for injection molding applications requiring very high stiffness, mechanical strength, dimensional stability and heat resistance.
Zytel 70G43HSLA BK099 PA66 is a 43% glass fiber reinforced, heat stabilized black polyamide 66 resin developed for injection molding. It provides very high rigidity, excellent mechanical strength and strong dimensional control for demanding automotive, electrical and industrial engineering components.
The grade is identified as PA66-GF43 and includes a release agent to support stable injection molding and efficient part removal. Compared with unreinforced or lower glass-filled PA66 grades, its 43% glass fiber content provides higher stiffness, reduced molding shrinkage and improved resistance to deformation under mechanical load.
Zytel 70G43HSLA BK099 also offers good high-temperature performance, abrasion resistance, chemical resistance and electrical properties. It is commonly used in automotive parts, furniture, domestic appliances, sporting goods, construction products and other reinforced structural applications.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 70G43HSLA BK099 PA66 resin with quotation support, TDS, SDS and global delivery service.
