描述
Zytel 70G30HSLR BK186LM PA66 is a 30% glass fiber reinforced, heat stabilized, hydrolysis resistant and laser markable polyamide 66 resin designed for injection molding applications. It is suitable for demanding parts exposed to heat, humidity, glycol coolant and long-term automotive under-the-hood environments.
Compared with standard PA66-GF30 grades, Zytel 70G30HSLR BK186LM PA66 adds hydrolysis resistance and laser marking capability while maintaining high stiffness, strength and dimensional stability. This makes it useful for radiator end tanks, thermostat housings, coolant connectors, water pump components, sensor housings and traceable engineering components.
Public product data identifies this grade as PA66-GF30 with density around 1.37 g/cm³, optimum melt temperature around 295°C, and recommended drying at 80°C for 2–4 hours.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 70G30HSLR BK186LM PA66 resin with quotation support, document assistance and global delivery service.
