MXD6 Plastic | Long Glass Fiber Reinforced MXD6 (MXD6-LGF) What is MXD6? Polyadipyl-m-benzoylamine, commonly referred to as MXD6 or nylon MXD6, is a high-performance engineering thermoplastic. Compared to other engineering plastics, MXD6 has higher mechanical strength and modulus. It is also a special high barrier nylon, with excellent resistance to oxygen and carbon dioxide. Unlike PVDC or EVOH, its barrier performance is not affected by temperature or humidity, making MXD6 ideal for high-temperature and humid conditions. Structural and Mechanical Performance MXD6 nylon exhibits high strength, high rigidity, high thermal deformation temperature, low thermal expansion, excellent dimensional stability, and low water absorption. Its mechanical properties change minimally after water absorption. MXD6 has low shrinkage for precision forming, excellent paintability at high temperatures, and outstanding barrier properties. Advantages of MXD6 Maintains high strength and rigidity over a wide temperature range High heat deflection temperature with low thermal expansion coefficient Low water absorption and minimal mechanical property reduction Small molding shrinkage, suitable for precision molding processes Excellent paintability, especially at high temperatures Outstanding barrier to oxygen, carbon dioxide, and other gases MXD6-LGF | Long Glass Fiber Reinforced MXD6 MXD6 can be compounded with long glass fibers, carbon fibers, minerals, and advanced fillers to produce composites with 50-60% glass fiber reinforcement. This results in exceptional strength and stiffness while maintaining a smooth, resin-rich surface ideal for painting, metal coating, or reflective housings. Key Advantages of MXD6-LGF High fluidity for thin walls: Can fill walls as thin as 0.5 mm even with 60% glass fiber content. Excellent surface finish: Resin-rich surfaces provide high gloss appearance despite high fiber content. Very high strength and stiffness: Comparable to many cast metals and alloys with 50-60% glass fiber. Good dimensional stability: Low shrinkage and tight tolerances; coefficient of linear expansion similar to many metals. MXD6-LGF TDS (Technical Data Sheet) Applications of MXD6-LGF MXD6-LGF replaces metals for high-quality structural parts in automotive, electronics, and electrical appliances. It performs well in environments requiring high mechanical strength and oil resistance, operating at 120–160℃ long-term. With glass fiber reinforcement, MXD6 maintains heat resistance up to 225℃, suitable for cylinder blocks, cylinder heads, pistons, and synchronous gears of automotive engines. MXD6/PPO alloys offer high temperature resistance, high strength, wear resistance, oil resistance, and excellent dimensional stability, enabling metal replacement in automotive body panels, fenders, wheel covers, and complex curved parts.
