描述
Zytel 70G30REF BK314LM PA66 is a 30% glass fiber reinforced polyamide 66 resin developed for demanding electrical and automotive cooling applications. It combines high mechanical strength and dimensional stability with enhanced hydrolysis resistance and reliable electrical insulation performance at elevated temperatures.
Celanese identifies this grade as an electrically friendly solution for vehicle propulsion cooling systems. It is designed to resist water-glycol coolant, dielectric fluids and other automotive liquids while helping reduce the risk of coolant contamination and metal corrosion in electrically sensitive systems.
Zytel 70G30REF BK314LM PA66 also provides heat stabilization, laser-marking capability and mold-release performance. Its laser-markable black formulation supports permanent identification and component traceability without requiring labels or secondary printing operations.
Compared with conventional PA66-GF30 grades, this material is particularly suitable for electric vehicle thermal-management components where mechanical strength, coolant resistance and electrical performance must be maintained simultaneously. Celanese technical literature lists a heat-aging capability of approximately 160°C based on tensile-strength retention testing.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 70G30REF BK314LM PA66 resin with quotation support, application selection and global delivery service.
