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.

PLA Plastic | Long Glass Fiber Reinforced PLA (PLA-LGF) What is PLA? Polylactic acid (PLA) is a biodegradable and eco-friendly polymer plastic, produced via pollution-free processes. PLA can naturally degrade and recycle in the environment, making it an ideal green polymer material and one of the most representative biodegradable plastics. PLA Structure and Heat Resistance The molecular structure of PLA affects its heat resistance, toughness, mechanical strength, degradability, and biocompatibility. PLA has a spiral molecular chain with low activity, resulting in slow crystallization after injection molding and relatively poor heat resistance. During hot processing, ester bonds may break partially, generating terminal carboxyl groups that accelerate thermal degradation. Long Glass Fiber (LGF) Reinforced PLA Reinforcing PLA with long glass fibers (PLA-LGF) improves mechanical strength, rigidity, and heat resistance. The fibers act as skeleton support, restricting polymer chain movement during heating and increasing thermal stability. Types of Fibers for PLA Reinforcement Fibers used for PLA enhancement include: Natural plant fibers: sisal, flax, linen, bamboo, coconut, wood fiber Animal fibers: silk Mineral fibers: basalt fiber Chemical fibers: glass fiber, carbon fiber Glass fiber and carbon fiber are widely used due to their high strength and modulus, while natural fibers are favored for biodegradability and renewable sources. Modified fibers blended with PLA have shown Vicat softening temperatures exceeding 140°C. Compared with Short Fiber (SGF) Long glass fiber reinforced PLA demonstrates superior mechanical properties compared with short fiber (SGF) reinforced PLA. It is more suitable for large structural parts, offering 1–3 times higher toughness and 0.5–1 times greater tensile strength and rigidity.

Long Carbon Fiber Carbon fiber exhibits outstanding properties, including extremely high axial strength and modulus, low density, and excellent specific performance. It shows no creep, outstanding fatigue resistance, excellent corrosion resistance, and maintains stability at very high temperatures in non-oxidizing environments. Carbon fiber also features good electrical and thermal conductivity, effective electromagnetic shielding, a low coefficient of thermal expansion, and strong anisotropy. Compared with traditional glass fiber, carbon fiber offers more than three times the Young’s modulus and approximately twice the modulus of aramid (Kevlar) fiber. It is insoluble and does not swell in organic solvents, acids, or alkalis, making it highly suitable for corrosive and demanding environments. One effective way to reduce the cost of carbon fiber applications is to combine it with engineering plastics such as nylon, creating high-performance composite materials with optimized cost-performance balance. As a result, carbon fiber reinforced nylon has become an important material system in modern composite engineering. Nylon itself is a high-performance engineering plastic, but it suffers from moisture absorption, limited dimensional stability, and mechanical properties far below those of metals. To overcome these limitations, fiber reinforcement has been applied since the 1970s. Carbon fiber reinforced nylon significantly improves strength, stiffness, thermal stability, creep resistance, wear resistance, and dimensional accuracy. Compared with glass fiber reinforced nylon, carbon fiber reinforced nylon offers superior damping behavior and overall mechanical performance. Therefore, carbon fiber reinforced nylon (CF/PA) composites have developed rapidly in recent years. In particular, for additive manufacturing, SLS (Selective Laser Sintering) technology is considered one of the most suitable methods for processing carbon fiber reinforced nylon materials.

PA6 Material Overview PA6 (Polyamide 6) is a widely used engineering plastic with excellent balanced performance. Its raw materials are readily available and cost-effective, making it accessible without dependence on foreign technology. However, PA6 has some limitations such as high water absorption, lower low-temperature impact toughness, and moderate dimensional stability. To overcome these limitations, PA6 is often reinforced with glass fiber (GF) to enhance mechanical properties. PA6-LGF (Long Glass Fiber Reinforced PA6) 1. Influence of Glass Fiber Content Glass fiber content is a key factor in the performance of reinforced composites. Increasing fiber content increases fiber density, thinning the PA6 matrix between fibers. This enhances impact toughness, tensile strength, and bending strength. Example: For PA6-LGF, increasing fiber content to 35% raised notch impact strength from 24.8 J/m to 128.5 J/m. However, excessive fiber content can reduce impact strength. Bending strength also improves as fibers transfer stress and absorb energy when broken, with experimental results showing bending modulus up to 4.99 GPa for 35% LGF. 2. Influence of Fiber Retention Length Fiber length significantly affects mechanical properties. When fiber length is below the critical length, increasing length improves resin-fiber bonding and tensile load resistance. When fiber exceeds the critical length, longer fibers absorb more impact energy and improve impact strength, as the number of fiber ends (crack initiation points) decreases. Example: At 40% fiber content, increasing fiber length from 4mm to 13mm improved tensile strength from 154.8 MPa to 164.4 MPa, with bending strength and notched impact strength increasing by 24% and 28%, respectively. Fibers longer than 7mm enhance warping resistance and mechanical stability under high temperature and humidity. Technical Data Reference (TDS) PA6-LGF can be reinforced with 20%-60% long glass fiber depending on product requirements. Compared to unreinforced PA6, PA6-LGF offers enhanced strength, heat resistance, impact resistance, dimensional stability, and reduced warping. The following TDS shows the data for PA6-LGF30. Applications of PA6-LGF PA6-LGF is widely used in automotive, electronic/electrical, and machinery/engineering parts. Automotive Parts Lightweight and miniaturization trends promote PA6-LGF use in engines, electrical systems, and body components. Electronic & Electrical Components Excellent flame retardancy and corrosion resistance make PA6-LGF suitable for switchgear, circuit breakers, contactors, connectors, and cable protection tubes. Mechanical & Engineering Parts Good impact resistance, wear resistance, and self-lubrication properties allow PA6-LGF to be used in machinery and engineering accessories.
