What is Long Glass Fiber (LGF)? Long glass fiber reinforced plastics (LFT) are engineered materials in which long glass fibers and additives are incorporated into a base thermoplastic. This significantly improves mechanical strength, heat resistance, dimensional stability, and the overall performance of the material. Why Reinforce with Long Glass Fiber? High heat resistance: LFT significantly increases the thermal performance, especially for nylon-based plastics. Reduced shrinkage & higher rigidity: Fiber reinforcement restricts polymer chain movement, improving dimensional stability and stiffness. Improved impact resistance: Reinforced plastics are less prone to stress cracking and have better toughness. High strength: Long glass fibers increase tensile, compressive, and bending strength. Flame retardancy: Most LFT materials are self-extinguishing due to additives and fiber content. Why Choose Long Glass Fiber over Short Glass Fiber? Longer fiber length significantly enhances mechanical properties. High specific stiffness and strength with excellent impact resistance, ideal for automotive applications. Superior creep resistance and dimensional stability for precision parts. Excellent fatigue resistance for long-life components. Improved stability under hot and humid environments. Minimal fiber damage during molding due to relative fiber movement in the mold.

Polyamide, which is also known by the trade name, Nylon, has excellent heat resistant properties, especially when combined with additives and filler materials. In addition to this, Nylon is very resistant to abrasion. Xiamen LFT offers a wide range of temperature-resistant nylons with many different filler materials. About PA66-LGF compounds Nylon 6,6, also written as nylon 6-6, nylon 66, or nylon 6/6, is a more crystalline version of nylon 6. It is also referred to as polyamide 66 or PA 66. It has improved mechanical properties due to its more ordered molecular structure. Nylon 66 for machining has improved temperature resistance and lower rates of water absorption when compared to standard nylon 6.  The advantages of nylon 6,6 are that the yield strength is higher than nylon 6 and nylon 610. It has high strength, toughness, rigidity, and low coefficient of friction in a wide temperature range. In addition, it is oil resistant and resistant to chemical reagents and solvents. However, PA66 has strong hygroscopicity and poor dimensional stability, which limits its application. In order to obtain nylon 66 engineering material with higher strength, it should be modified by glass fiber reinforcement. 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 compression molding, and complex components can also be formed. Therefore, long glass fiber reinforced nylon 66 can be widely used in building materials, aerospace, electronic devices, furniture and other fields, especially in the automotive industry application market. The production process of long glass fiber reinforced nylon 66 is different from that of short glass fiber reinforced nylon 66. The short glass fiber reinforced nylon 66 particle is chopped under the friction and shearing of screw and barrel, and the short glass fiber reinforced nylon 66 particle is obtained with the length of glass fiber monofilament about 0.5mm. The length of some glass fiber monofilament in the final product is lower than the critical length of reinforcement, and the glass fiber is easy to be extracted from the nylon 66 matrix when the product is stressed. The strength of glass fiber is not fully utilized, and the mechanical properties of the product are not high. Long glass fiber reinforced nylon 66 has better reinforcement effect and dimensional stability, and the rigidity, tensile, bending, impact resistance and fatigue resistance of the manufactured products are better, and the service life is longer.

It has a crystallinity of 80%–90%, a softening point of 125–135℃, and can be used up to 100℃. Compared to low-density polyethylene, HDPE has better hardness, tensile strength, and creep resistance. It also offers superior wear resistance, electrical insulation, toughness, and cold resistance. HDPE has excellent chemical stability—it is insoluble in organic solvents at room temperature and resistant to acids, alkalis, and various salts. Long Glass Fiber Glass fiber reinforced plastics (GFRP) are made by adding glass fibers and other additives to pure plastics, which significantly extends the material’s application range. These reinforced materials are commonly used for structural parts in products made from PP, ABS, PA66, PA6, HDPE, PPA, TPU, PEEK, PBT, PPS, and others. Advantages High heat resistance: Glass fiber is heat resistant, so reinforced plastics can withstand much higher temperatures, especially nylon-based plastics. Reduced shrinkage and improved rigidity: Glass fiber restricts polymer chain movement, decreasing shrinkage and significantly improving rigidity. Improved impact resistance: Reinforced plastics resist stress cracking and have much higher impact strength. Enhanced mechanical strength: Tensile strength, compressive strength, and bending strength are greatly improved. Flame retardancy: Addition of glass fiber and other additives reduces combustibility; most reinforced plastics cannot be ignited. Datasheet Contact Us

They are frequently used to replace metal for applications in which light weighting, improved impact strength, elastic modulus, and material strength are required.

PEEK-Long carbon fiber Polyetheretherketone (PEEK), the complete English name for polyetheretherketone, is a specialty engineering plastic with excellent performance, and has more advantages than other specialty engineering plastics, such as wear resistance, high temperature resistance, high strength and high modulus, flame retardant and radiation resistant, and so on. In addition polyetheretherketone (PEEK) has good thermal stability and melt flow above the melting point, so polyetheretherketone (PEEK) also has the typical processing properties of thermoplastics. PEEK resin is nontoxic, lightweight, corrosion-resistant, and one of the closest materials to the human skeleton, which is well compatible with the musculature, so it is often used instead of metal to make human bones. Carbon fiber-reinforced PEEK composites make up for the weaknesses of toughness and deviations in impact strength. Carbon fiber-reinforced PEEK composites can exhibit high mechanical strength and hydrolytic stability under conditions such as hot water, steam, solvents, and chemical reagents, and can be used to prepare various medical devices that require high-temperature steam sterilization. Advantages of PEEK-LCF PEEK has high rigidity, good dimensional stability, low coefficient of linear expansion, and can withstand great stress without significant elongation over time, and its low density and good processing properties make it suitable for parts with high requirements for fineness. Among these elements, carbon fiber materials overlap highly with the characteristics of PEEK. Carbon fiber is not only one of the typical lightweight materials, it is also outstanding in terms of mechanical properties. As a result, carbon fiber reinforced PEEK composites can reduce weight by at least 70% compared to traditional metal materials. PEEK material itself is very wear-resistant, and good interface bonding with carbon fibers to further enhance its wear resistance, through the carbon fiber reinforced PEEK composite parts and cobalt alloy materials for wear comparison experiments, the results show that: at 23 ℃, using the M-200 wear machine at 400 rpm after 100 minutes of wear, found that the carbon fiber reinforced PEEK composite surface smooth The wear marks were small, and the carbon fiber bonded well with PEEK without fiber extraction. In contrast, the cobalt alloy surface wear marks are very obvious, even a large number of wear particles appear, the metal internal impurities image visible. PEEK exhibits high mechanical strength and hydrolytic stability in hot water, steam, solvents and chemical reagents, etc. Datasheet for reference PEEK-LCF application Q&A 1. What are the types of thermoplastic carbon fiber composites? Carbon fiber thermoplastic composites are composites with carbon fiber as the reinforcing material and thermoplastic resin as the matrix. From the reinforcement method of carbon fiber, it can be divided into long-cut carbon fiber (LCF) reinforced thermoplastic composites, short-cut carbon fiber (SCF) reinforced thermoplastic composites and continuous carbon fiber (CCF) reinforced thermoplastic composites. Long-cut carbon fiber and short-cut carbon fiber mainly refer to the application length of carbon fiber materials, there is no strict fixed distinction between the two, generally between a few millimeters to a few centimeters, the more common specifications are 6mm, 12mm, 20mm, 30mm, 50mm. Carbon fiber thermoplastic composites can also be classified according to the thermoplastic resin. There are many common thermoplastic resins, such as PE, PP, PVC, etc. However, thermoplastic resin composites with carbon fiber reinforcement are mostly used in aerospace, precision equipment and other demanding working environments, therefore, carbon fiber thermoplastic composites are more often made of polyether ether ketone (PEEK), PPS, polyimide ( PI), polyetherimide (PAI) and other mid- to high-end thermoplastic resins as the matrix to achieve the optimization of material performance. 2. How does thermoplastic carbon fiber composite material achieve low cost and environmental protection? Thermoplastic carbon fiber composites are used to make parts for high-end machinery. They have excellent machinability, vacuum forming, stamping mold plasticity, and bending processability. For example, Teijin has been able to add a recycling process to the process according to specific needs, and to shred and mold the corners of thermoplastic carbon fiber composite materials after stamping to make recycled materials for making small products or for molding nuts and studs on carbon fiber prototypes. This method can greatly reduce the loss of raw materials, improve the efficiency of the use of thermoplastic carbon fiber composite materials, reduce the overall cost, and thus achieve the purpose of environmental protection. In addition, thermoplastic carbon fiber composites can reduce the molding cycle time compared with thermoset carbon fiber composi...

PPA Plastic PPA is produced by the polycondensation of aliphatic diamines or aromatic diamines containing benzene rings. Compared with aliphatic polyamides, the introduction of rigid benzene rings into the molecular chain significantly improves mechanical strength and heat resistance, while reducing water absorption. Compared with fully aromatic polyamides, semi-aromatic polyamides contain flexible aliphatic segments, resulting in lower melting points and improved processability. Thanks to its balanced performance, PPA has become one of the most important special engineering plastics, widely used in electronics, electrical components, and the automotive industry. PPA Filled with Long Glass Fiber Composites Glass fiber reinforced PPA composites are considered one of the best materials for metal replacement due to high temperature resistance, high strength, and low density. Long glass fiber reinforced PPA shows significantly better mechanical properties compared with short glass fiber reinforced materials.
