描述
Zytel 70K20HSL BK284 PA66 is an aramid fiber reinforced, heat stabilized polyamide 66 resin developed for injection molding applications. It is designed for mechanical components where sliding performance, wear resistance and long service life are important.Zytel 70K20HSL BK284 PA66 is an aramid fiber reinforced, heat stabilized and lubricated polyamide 66 resin developed for injection molded components requiring good wear resistance, low friction and dimensional stability.
Compared with conventional glass fiber reinforced nylon, aramid fiber reinforcement is less abrasive to contacting metal and plastic surfaces. This makes Zytel 70K20HSL BK284 suitable for gears, bushings, bearing cages, guides and other moving components requiring controlled friction and reduced mating-surface wear.
The heat-stabilized formulation supports performance at elevated operating temperatures, while lubrication and mold-release additives help improve processing consistency and demolding. Celanese identifies Zytel PA as a broad engineering nylon portfolio offering different reinforcement systems, heat resistance and application-specific performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 70K20HSL BK284 PA66 resin with quotation support, TDS, SDS and global delivery service.

Processing Recommendations
Zytel 70K20HSL BK284 PA66 should be dried before injection molding because PA66 absorbs moisture during storage. Proper drying helps maintain mechanical performance, surface quality and dimensional consistency.
Melt temperature, mold temperature, injection speed and holding pressure should be adjusted according to part thickness, flow length and dimensional requirements. Excessive residence time and unnecessary shear should be avoided to protect the reinforcement and maintain consistent molded-part performance.
