MXD6 Polyadipyl-m-benzoylamine, abbreviated as mxd6, resin has higher mechanical strength and modulus than other engineering plastics, is also a special high barrier nylon material. Although the barrier of mxd6 is slightly worse than that of pvdc and evoh, its barrier is not affected by temperature and humidity, which is especially suitable for high temperature and humid occasions. In today's barrier packaging and plastic instead of steel general trend, nylon mxd6 has become one of the most eye-catching new plastic varieties. Structure performance: MXD6 nylon material has high strength, high rigidity, high thermal deformation temperature, small thermal expansion coefficient; Dimensional stability, low water absorption rate and small size change after water absorption, mechanical strength changes less; Forming shrinkage is small, suitable for precision forming processing; Excellent coating performance, especially suitable for high temperature surface coating; Excellent barrier to oxygen, carbon dioxide and other gases. Excellent mechanical and thermal properties and high strength, high modulus and heat resistance, high barrier, excellent cooking resistance. MXD6-LGF MXD6 can be compounded with glass fiber for use in fiberglass reinforced materials containing 50-60% glass fiber for exceptional strength and stiffness. Even when filled with high glass content, its smooth, resin-rich surface produces a fibre-free high gloss surface, ideal for painting, metal-plating, or creating naturally reflective shells. 1. Suitable for high liquidity of thin wall It is a very fluid resin that can easily fill thin walls as thin as 0.5 mm thick even when the glass fiber content is as high as 60%. 2. Excellent surface finish A resin-rich perfect surface has a highly polished appearance, even with a high glass fiber content. 3. High strength and stiffness The tensile and flexural strength of MXD6 is similar to that of many cast metals and alloys with the addition of 50-60% glass fiber reinforced material. 4. Good dimensional stability At ambient temperatures, the linear expansion coefficient (CLTE) of MXD6 glass fiber composites is similar to that of many cast metals and alloys. Strong reproducibility due to low shrinkage and the ability to maintain tight tolerances (length tolerances as low as ± 0.05% if properly formed). MXD6 replaces metal to produce high-quality structural parts for automobiles, electronics and electrical appliances In automobile parts, many occasions require material products with high mechanical strength and good oil resistance, and can be used in the range of 120 ~ 160℃ for a long time. Glass fiber reinforced MXD6 heat resistant temperature up to 225℃, high rate of strength retention at high temperature, can be used in the cylinder block, cylinder head, piston, synchronous gear, etc. MXD6/PPO alloy has high temperature resistance, high strength, oil resistance, wear resistance, good dimensional stability and other properties, can be used for the vertical outer plate of the automobile body, front and rear fenders, wheel covers and almost can not use steel plate stamping forming curved parts and automobile chassis. Datasheet for reference Application fileds Production process Xiamen LFT composite plastic Co., Ltd Q. How to choose the fiber content of the product? Is the larger product suitable for higher fiber content material? A. This is not absolute. The content of glass fiber is not more is better. The suitable content is just to meet the requirements of each products. Q. Under what circumstances can long fiber replace short fiber? What are the common alternative materials? A. Traditional staple fiber materials can be replaced with long glass fiber and long carbon fiber LFT materials in the case of customers whose mechanical properties cannot be met or where higher metal substitutes are desired. For example, PP long glass fiber is often replacing nylon reinforced glass fiber, and nylon long glass fiber is replacing PPS series. Q. Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds? A. There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber.

MXD6-LGF (Long Glass Fiber Reinforced MXD6) is a high-performance thermoplastic composite made from MXD6 polyamide resin reinforced with long glass fibers. Through advanced pultrusion technology, continuous glass fibers are fully impregnated with MXD6 resin before pelletizing, ensuring excellent fiber length retention and the formation of a highly reinforced internal structure after injection molding. Compared with standard MXD6 or short glass fiber reinforced MXD6, MXD6-LGF offers significantly enhanced tensile strength, stiffness, impact resistance, creep resistance, and dimensional stability. MXD6 resin itself provides excellent mechanical strength, high heat resistance, low moisture absorption compared with traditional polyamides, outstanding gas barrier properties, chemical resistance, and good dimensional accuracy. Combined with long glass fiber reinforcement, MXD6-LGF delivers superior load-bearing capability, fatigue resistance, and long-term reliability, making it an ideal lightweight engineering material for automotive structural components, electrical and electronic parts, industrial applications, and other demanding environments requiring high strength, heat resistance, and dimensional stability. Typical Applications MXD6-LGF combines the excellent mechanical strength, heat resistance, dimensional stability, and gas barrier properties of MXD6 resin with the superior reinforcement effect of long glass fibers. It provides significantly improved tensile strength, stiffness, creep resistance, fatigue performance, and dimensional accuracy while maintaining good chemical resistance and lightweight characteristics, making it suitable for demanding automotive, electrical, industrial, and structural applications requiring high performance and long-term reliability. Automotive Applications Structural components, engine compartment parts, battery system components, and lightweight automotive parts requiring high strength, heat resistance, dimensional stability, and long-term reliability. Electrical & Electronics Connectors, sensor housings, electronic components, and precision parts requiring excellent mechanical performance, low moisture absorption, heat resistance, and dimensional accuracy. Industrial & Mechanical Components Pump components, valve bodies, gears, housings, and mechanical parts requiring high stiffness, fatigue resistance, chemical resistance, and long-term durability.
