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.

Polyphenylene Sulfide (PPS) PPS (polyphenylene sulfide) is a high-performance engineering plastic with metal-like hardness, excellent strength, and exceptional thermal, chemical, and electrical resistance. It offers flame retardancy (V0), low warping, and high wear resistance. Compared with metals, PPS is lightweight, which is ideal for vehicles, ships, and aircraft. PPS combines high strength with low weight, excellent corrosion resistance, and outstanding insulation properties even under high temperature, high humidity, and high-frequency conditions. PPS is also wear-resistant, suitable for self-lubricating bearings, gears, and seals, and allows one-step molding unlike metals which require multiple processes. Long Glass Fiber Compounds Our "Center Fill" LFT compounds are produced by impregnating thousands of glass fiber filaments with molten PPS resin, then cutting the resultant material into pellets. This process ensures uniform fiber distribution and superior mechanical properties.

PA6-LGF PA6 modified plastics use pure PA6 as the matrix and enhance internal and external properties through blending, filling, strengthening, copolymerization, crosslinking, and other methods. They account for approximately 15% of PA6 applications. Long glass fiber content ranges from 20%–60%, adjusted according to product requirements, providing high strength, superior heat resistance, good impact resistance, and lightweight alternatives to certain metals. Common applications include power tool shells, garden tools, gears, sports equipment, and automotive parts. Other Specifications of PA6-LGF Flame Retardant PA6: PA6 is naturally flammable, but adding flame retardants changes its combustion properties. Mechanical mixing incorporates nitrogen, phosphorus, bromine-based, or mineral flame retardants. These materials are suitable for switches, low-voltage electrical housings, wiring terminals, and circuit breakers. Toughened PA6: Incorporating toughening agents improves low-temperature resistance, flexibility, fluidity, reduces shrinkage and water absorption, enhances impact and aging resistance. Ideal for baby carriage parts, rolling belts, line clips, and connectors. Applications Beyond daily applications, PA6 modified plastics are increasingly used in high-end fields such as rail transit, medical devices, military, and aerospace. TDS for Reference Nylon reinforced materials are made from PA6/PA66 resins with 20–60% glass fiber to increase strength. 30% fiber content is most common, but 40–50% can be used based on product requirements. Advantages of Long Glass Fiber Compounds 1. High-temperature resistance improves significantly after glass fiber reinforcement, especially for nylon plastics. 2. Shrinkage decreases and rigidity increases due to limited polymer chain movement. 3. Stress cracking is reduced and impact resistance improves. 4. Mechanical properties such as tensile, compression, and bending strength are enhanced. 5. Flame retardancy improves; most reinforced materials become self-extinguishing.
