描述
Zytel 70G50HSLA BK039B PA66 is a 50% glass fiber reinforced, heat stabilized polyamide 66 resin developed for demanding injection molding applications. Its high reinforcement level provides considerably greater rigidity, structural strength and dimensional control than unreinforced or lower glass-filled PA66 materials.
The material is suitable for heavily loaded automotive, electrical and industrial components requiring resistance to deformation under mechanical load. Celanese positions reinforced Zytel PA materials for applications requiring adjustable levels of stiffness, strength, heat resistance and processing performance.
The BK039B designation identifies the black color formulation. Zytel 70G50HSLA BK039B PA66 can be evaluated for automotive structural parts, engine-compartment components, mechanical brackets, industrial housings and selected metal-replacement applications.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 70G50HSLA BK039B PA66 resin with quotation support, TDS, SDS and global delivery.

Processing Recommendations
Zytel 70G50HSLA BK039B PA66 should be thoroughly dried before injection molding because PA66 absorbs moisture during transportation and storage. Proper moisture control helps maintain surface quality, mechanical properties and dimensional stability.
Glass-fiber-reinforced Zytel materials generally require sufficiently fast cavity filling, especially for thin sections. Excessive screw speed and shear should be avoided because glass-fiber breakage can reduce the mechanical performance of molded components. Final temperatures, pressures and residence time should follow the grade-specific technical data sheet.
