The mechanical properties of long glass fiber reinforced nylon 66 (LGFR-PA66) are obviously better than those of short glass fiber reinforced nylon 66 (SGFR-PA66), and the molding processing performance is also better. It can be molded by various molding methods such as injection molding and extrusion molding, and complex components can also be formed.

PA6 refers to polyamide 6, which is a widely used engineering plastic with excellent mechanical strength, wear resistance, and chemical stability. Adding long glass fibers to PA6 can significantly enhance the material’s mechanical properties, such as strength, rigidity, impact resistance, and dimensional stability.

One of the remarkable features of PBT-GF is its excellent dimensional stability. The presence of glass fibers greatly reduces the material's tendency to expand or contract under varying temperature conditions. This property ensures that PBT GF retains its shape and size, making it suitable for applications that demand tight tolerances and precise dimensions.

MXD6 long glass fiber reinforced material offers excellent mechanical strength, dimensional stability, and outstanding gas barrier properties. It is ideal for applications requiring high stiffness, heat resistance, and reduced permeability, such as automotive components, electronics, and industrial parts.

PLA itself is an environmentally friendly thermoplastic, known for its biodegradability. However, it has limited mechanical properties, such as strength, toughness, and heat resistance. By incorporating long glass fibers, the performance of PLA is significantly improved, making it suitable for demanding applications.

Fiber-reinforced PPA has high temperature resistance, high strength and low density, so it is considered the best resin to replace steel with plastic in the future. It can be used in many industrial and civil fields, including automobiles, equipment, entertainment, food processing, communications, electronics and electrical , power tools, gardening, etc.

PP long glass fiber reinforced composite is a high-performance thermoplastic material made by compounding polypropylene (PP) with continuous long glass fibers. This material offers a significant improvement in mechanical properties compared to standard PP.

TPU introduction Thermoplastic polyurethane (TPU) elastomers are linear polymers formed by the copolymerization of hard and soft chain segments, which have physical properties such as tensile, abrasion and heat resistance, and elasticity similar to rubber. Thanks to the excellent product performance, the application fields of TPU are expanding, including daily consumer goods, construction, medical, military, automotive, agriculture and many other fields. New products and applications are also emerging, such as large-diameter hoses (shale gas extraction), charging cables for new energy vehicles, foamed TPU (ETPU) sports shoes midsoles prepared by supercritical foaming process, invisible braces, etc. Fiber reinforced modified TPU composites TPU has good impact resistance, but in some applications, high modulus of elasticity and very hard material is required. Glass fiber reinforced modification is a common technical means to improve the elastic modulus of the material. Through modification, thermoplastic composites with many advantages such as high elastic modulus, good insulation, heat resistance, good elastic recovery, good corrosion resistance, impact resistance, low coefficient of expansion and dimensional stability can be obtained. Long glass fiber VS Short glass fiber Compared with the short fiber, long fiber has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher toughness than short fiber, and the tensile strength is increased by 0.5-1 times. Thermoplastics VS Thermosets Thermosets: when heated for the first time, they can soften and flow, and when heated to a certain temperature, they produce a chemical reaction a cross-chain curing and become hard, this change is irreversible, after that, when heated again, they can no longer become soft and flow. Thermoplastic: thermoplastic resin is the main component, and various additives are added to form a plastic. Under certain temperature conditions, plastic can be softened or melted into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repeated is only a physical change. Advantages Thermosets: Thermoset plastics retain their strength and shape even when heated. This makes thermoset plastics ideal for producing permanent parts and large, strong shapes. In addition, these parts have excellent strength properties (despite their fragility) and do not lose significant strength when exposed to higher operating temperatures. Thermoplastics: Thermoplastics are the most widely used plastics and typically have high chemical and thermal resistance, as well as a high strength structure that is not easily deformed. It is made of thermoplastic resin as the main component with various additives.  Thermoplastic products have excellent electrical insulation, with very low dielectric constant and dielectric loss, suitable for high Frequency and high voltage insulation materials.

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.

PLA Plastic PLA (polylactic acid) is a bio-based polyester and one of the most promising "green plastics" due to its biodegradability, biocompatibility, and high mechanical strength. PLA products can fully degrade into CO₂ and water via microorganisms, and are non-toxic and non-irritating. Mechanically, PLA is comparable to polypropylene, while its gloss, clarity, and processability resemble polystyrene. Its lower processing temperature allows production via injection molding, extrusion, blow molding, spinning, and other common plastic processing methods. PLA is widely applied in disposable plastics, packaging, fibers, nonwovens, chemical, medical, pharmaceutical, and 3D printing industries. PLA is increasingly recognized as a key material to reduce plastic pollution.
