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

It features excellent biocompatibility, biodegradability, and mechanical strength. Under composting conditions, PLA can be fully degraded into CO₂ and water, making it non-toxic and environmentally friendly. PLA has mechanical properties similar to polypropylene, while its transparency and gloss are comparable to polystyrene. It can be processed using standard thermoplastic methods such as injection molding, extrusion, blow molding, and 3D printing. It is widely used in packaging, fibers, medical, pharmaceutical, and disposable products, and is considered a key material in reducing plastic pollution. Long Glass Fiber Reinforced PLA (LGFPLA) Glass fiber is an inorganic non-metallic material with excellent properties such as high strength, heat resistance, corrosion resistance, and insulation. It is widely used as a reinforcement material in composites. Long glass fiber reinforced PLA (LGFPLA) refers to PLA composites reinforced with glass fibers typically ranging from 10–25 mm in length. After injection molding, fibers form a 3D network structure, significantly improving mechanical performance. LGFPLA belongs to the LFT (Long Fiber Thermoplastic) material family. Standard LGFPLA pellets are typically 12 mm or 25 mm in length. Fiber content ranges from 20% to 60%, and colors can be customized according to customer requirements.

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.
