What is PA6 Plastic? Polyamide (PA), commonly known as Nylon, is a thermoplastic engineering plastic containing amide groups (-NHCO-) in its molecular chain. It can be divided into aliphatic and aromatic polyamides and is one of the earliest and most widely used engineering plastics. Polyamide materials are widely used in fibers, engineering plastics, and films. According to the number of carbon atoms in the molecular structure, many types of polyamides can be produced, among which PA6, PA66, and PA610 are the most commonly used. Introduction to PA6 (Polyamide 6) PA6 is an aliphatic polyamide known for its lightweight properties, high mechanical strength, wear resistance, and excellent processing performance. It is widely used in engineering plastics, fibers, automotive components, and industrial applications. However, PA6 molecules contain highly polar amide groups that easily form hydrogen bonds with water molecules. As a result, PA6 has relatively high water absorption, which may affect dimensional stability and impact performance under dry or low-temperature conditions. Advantages of Nylon 6 (PA6) High mechanical strength and excellent toughness Outstanding fatigue resistance under repeated bending High heat resistance and softening point Low friction coefficient and excellent wear resistance Excellent resistance to oils, alkalis, and general solvents Good anti-aging and weather resistance Self-extinguishing, non-toxic, and odorless Excellent electrical insulation performance Lightweight and easy to process and mold Disadvantages of Nylon 6 (PA6) High water absorption rate Poor dimensional stability in humid environments Limited resistance to strong acids and oxidants Surface discoloration and oxidation under long-term high temperatures Strict injection molding moisture requirements Possible deformation and warpage during molding Why Fill PA6 with Long Glass Fiber? Although PA6 has excellent mechanical properties and processing performance, its high water absorption and dimensional instability limit its use in high-performance engineering applications. To improve the overall performance of PA6, reinforcement modification is commonly used. Adding long glass fiber (LGF) or carbon fiber significantly enhances: Mechanical strength Impact resistance Dimensional stability Heat resistance Fatigue resistance Structural rigidity Long glass fiber reinforced PA6 is widely used in automotive, industrial, and structural engineering applications. Applications of PA6-LGF PA6 reinforced with 30% long glass fiber (LGF30) is an ideal engineering material for: Power tool housings and components Automotive structural parts Engineering machinery components Industrial load-bearing structures Mechanical and electrical equipment parts Compared with unreinforced PA6, the fatigue resistance strength can be increased by up to 2.5 times. Processing & Forming Guidelines for PA6 + 30% LGF Adding 30% long glass fiber can reduce PA6 shrinkage from approximately 1–1.5% down to around 0.3%. Excessive recycled material should be avoided, as it may reduce mechanical properties and cause discoloration. Recycled material should generally not exceed 25% and must be fully dried before processing. Fiber orientation during injection molding may cause warpage; proper gate design and mold temperature control are recommended. Slow cooling in hot water treatment can help reduce internal stress and deformation. Customers & Staff Certificates

Long carbon fiber Carbon fiber has many excellent properties, high axial strength and modulus, low density, high specific performance, no creep, super high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance. But is there a way to reduce the price of carbon fiber? That is to mix it with relatively cheap nylon material to form a composite material with good performance and meet the requirements. In that case, there is no doubt that carbon fiber nylon will definitely have a place in the composite material. Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness are also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance. Therefore, carbon fiber reinforced nylon (CF / PA) composites have developed rapidly in recent years. And for 3D printing using SLS technology is the most suitable technical means to achieve carbon fiber reinforced nylon.

PA66 Long Glass Fiber Reinforced Thermoplastic (PA66-LGF) Polyamide 66 (PA66) is one of the most widely used engineering thermoplastics. It offers excellent mechanical strength, wear resistance, insulation properties, and chemical resistance, making it suitable for demanding industrial applications. However, PA66 also has limitations such as relatively high water absorption, dimensional instability under humidity, and reduced impact performance at low temperatures. To overcome these weaknesses, long glass fiber reinforcement is widely used to significantly enhance its performance. Why Reinforce PA66 with Long Glass Fiber? Adding long glass fiber (LGF) into PA66 resin significantly improves its mechanical and thermal properties while maintaining good processability. Improved tensile strength and flexural strength Higher impact resistance Enhanced heat deflection temperature Better dimensional stability Improved chemical resistance The performance improvement is closely related to fiber content. Typically, PA66 with 20%–40% long glass fiber shows a significant increase in strength, stiffness, and load-bearing capability. Key Advantages of PA66-LGF Materials 1. High Mechanical Strength Long glass fiber reinforcement greatly improves tensile, flexural, and impact strength, making PA66 suitable for structural components. 2. Excellent Heat Resistance PA66-LGF materials maintain stability under high temperatures and are suitable for automotive under-the-hood applications. 3. Improved Dimensional Stability Reduced shrinkage and warpage ensure better precision in molded parts. 4. Enhanced Wear Resistance Ideal for moving and load-bearing components such as gears and mechanical housings.
