PA6 & PA6-LGF Long Glass Fiber Reinforced Nylon PA6, also known as Nylon 6, is a high-performance polyamide widely used in engineering plastics, fibers, and films. It is a thermoplastic polymer with repeating amide groups (-NH-CO-) in the main chain, offering strong mechanical properties and versatile processing capabilities. What is PA6 Plastic? PA6 is an aliphatic polyamide that provides excellent strength, wear resistance, and chemical resistance to weak acids, alkalis, and certain organic solvents. Its lightweight and processable nature make it widely applied in fibers, engineering plastics, and thin films. However, the polar amide groups in PA6 easily form hydrogen bonds with water molecules, which can result in high moisture absorption, dimensional changes, and reduced impact strength in dry or low-temperature conditions. Advantages of PA6 High mechanical strength and toughness with excellent tensile and compressive properties Outstanding fatigue resistance, maintaining strength after repeated bending High softening point, heat resistant Low friction and wear-resistant surface Corrosion resistance to alkalis, salts, weak acids, oils, and most solvents Self-extinguishing, non-toxic, odorless, and good weather and biological resistance Excellent electrical insulation even in high humidity environments Lightweight, easy to dye, and easy to mold due to low melting viscosity Limitations of PA6 High moisture absorption (up to 3% when saturated) Poor light and thermal stability; prolonged high-temperature exposure may cause discoloration and surface cracking Strict injection molding requirements; trace moisture can affect product quality Dimensional stability is sensitive to thermal expansion and wall thickness variations Not resistant to strong acids or oxidizing agents; unsuitable for acid-resistant applications Why Reinforce PA6 with Long Glass Fiber? To overcome the natural limitations of PA6, long glass fiber (LGF) reinforcement is applied. PA6-LGF composites combine the lightweight, chemical, and heat resistance of PA6 with the mechanical strength and dimensional stability of long glass fibers. LGF reinforcement improves tensile, compressive, and flexural strength, reduces shrinkage, enhances fatigue resistance, and provides improved thermal and chemical stability. This makes PA6-LGF ideal for high-performance structural components. Applications of PA6-LGF PA6 reinforced with 30% long glass fiber (30% LGF) is widely used in: Power tool shells and components Engineering machinery parts Automobile structural and functional components The composite improves mechanical strength, dimensional stability, heat resistance, aging resistance, and fatigue resistance. Its fatigue strength can be up to 2.5x that of unreinforced PA6. Processing and Forming Tips for 30% PA6-LGF Shrinkage is reduced to ~0.3% compared with 1–1.5% for pure PA6. Excessive fiber content may cause surface floating fibers and poor compatibility. 30% LGF is recommended for balanced performance. Recycled material content should be kept below 25% to avoid color and mechanical property degradation. Gradual cooling after molding prevents warping due to fiber orientation during injection molding. Mold design, gate position, and temperature control are critical. Customers & Staffs Certificates

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.

Polyamide 6 (PA6) Material Polyamide 6 (PA6) has chemical and physical properties very similar to PA66. However, differences in molecular structure lead to distinct performance characteristics. PA6 features a lower melting point and a wider processing temperature window, offering better impact resistance and solubility resistance than PA66, while also exhibiting higher moisture absorption. Since many quality characteristics of plastic parts are affected by hygroscopicity, molding shrinkage is largely influenced by crystallinity and moisture absorption. Therefore, these factors must be carefully considered when designing PA6 products. Fiber-reinforced PA6 effectively reduces shrinkage and mitigates issues caused by moisture absorption. Its high crystallinity and excellent flowability contribute to improved dimensional stability and overall part performance. Datasheet Nylon products should be used with attention to dimensional deviation caused by thermal expansion and moisture absorption. Conventional PA6 also shows limited acid resistance and UV resistance. Long-term exposure to high temperatures may cause thermal oxidation, resulting in discoloration and eventual material degradation. Therefore, unmodified nylon is generally not recommended for outdoor applications. Carbon fiber reinforced modified PA6 significantly improves creep resistance, rigidity, wear resistance, and mechanical strength, enabling stable performance in outdoor and demanding environments. *Tip: Poor compatibility between carbon fiber and PA6 may lead to fiber floating and reduced mechanical properties. Xiamen LFT’s PA6 composites feature excellent fiber–matrix compatibility, effectively avoiding these issues.

With trends toward lightweight and compact automotive design, under-the-hood temperatures continue to rise. Carbon fiber reinforced PA6 meets these demanding requirements and is widely used in automotive engine components, electrical systems, body structures, and airbag-related parts. Due to its excellent mechanical properties, dimensional stability, heat resistance, and aging resistance, carbon fiber reinforced PA6 is also commonly applied in mechanical parts and aerospace equipment components. Long carbon fiber reinforced PA6 features high flowability, high rigidity, excellent mechanical strength, low shrinkage, creep resistance, thermal stability, wear resistance, oil resistance, uniform fiber dispersion, and good surface gloss. Typical applications include power tools, fishing equipment, automotive parts, machinery components, and office accessories.

Nylon 66 material for machining has improved temperature resistance and lower rates of water absorption when compared to standard nylon 6.

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.
