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.

What is PA12? PA12, scientifically known as polydodecalactam (Nylon 12), is a semi-crystalline thermoplastic polymer. Its primary raw material is derived from petrochemical sources such as butadiene. PA12 features a unique crystal structure compared to other polyamides, offering excellent electrical insulation performance and low sensitivity to moisture. It also provides outstanding flexibility, impact resistance, and chemical stability. What is PA12-LGF? PA12-LGF is a high-performance composite material reinforced with long glass fibers based on PA12 resin. The addition of long fibers significantly enhances the structural and thermal properties of the material. High temperature resistance Excellent dimensional stability Superior toughness and impact resistance Good electrical insulation Strong corrosion resistance High mechanical strength Datasheet (Reference) Applications PA12-LGF materials are widely used in: Automotive components Sports equipment Solar and photovoltaic systems Industrial structural parts Product Details Grade Color Fiber Length Sample MOQ Package Port of Loading Lead Time PA12-NA-LGF30 Natural (customizable) ~12 mm (customizable) Available 25 KG 25 KG/Bag Xiamen Port 7–15 days About Us Xiamen LFT Composite Plastic Co., Ltd. specializes in long fiber reinforced thermoplastics (LFT & LFRT), including Long Glass Fiber (LGF) and Long Carbon Fiber (LCF) materials.
