描述
Zytel 74G50ARX ECO-R 311 BLK1 PA66 is a 50% glass fiber reinforced sustainable nylon resin from Celanese Zytel ECO-R series. The material is based on a PA66+PA6 matrix reinforced with 50% glass fiber, with 30% post-industrial recycled content (R30) by weight in the finished product.
The high glass fiber reinforcement level provides excellent stiffness, mechanical strength and dimensional stability, making it suitable for demanding structural applications where weight reduction and metal replacement are required. Celanese designed this grade primarily for automotive applications requiring high mechanical performance and sustainable material solutions.
Compared with standard reinforced PA66 grades, Zytel 74G50ARX ECO-R 311 BLK1 offers improved sustainability while maintaining engineering performance. The heat-stabilized formulation supports long-term use under elevated temperatures, while the black BLK1 formulation provides consistent appearance for molded components.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Zytel 74G50ARX ECO-R 311 BLK1 PA66 resin with quotation support, TDS, SDS and delivery service.
