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 Polyamide 66 plastic? PA66 melting point 260~265℃, glass transition temperature (dry state) is 50℃. Density is 1.13~1.16 g/cm3. PA66 has low water absorption, excellent dimensional stability and high rigidity. Higher melting point, can be used for a long time in harsh environments, in a wide range of temperatures can still maintain sufficient stress, continuous use temperature of 105 ℃. Long glass fiber reinforced composite Glass fiber reinforced plastic is based on the original pure plastic, filling glass fibers and other additives, so as to improve the scope of use of the material. Generally speaking, most of the glass fiber reinforced materials are used in the structural parts of the products, which is a kind of structural engineering materials, such as: PP, ABS, PA66, PA6, TPU, PPA, PBT, PEEK, PBT, PPS and so on. Advantages 1)After glass fiber reinforcement, glass fiber is a high temperature resistant material, therefore, the heat-resistant temperature of reinforced plastics is much higher than before without glass fiber, especially nylon plastics. 2)After the glass fiber reinforcement, due to the addition of glass fiber, the plastic polymer chain is restricted to move with each other, therefore, the shrinkage of reinforced plastics decreases a lot, and the rigidity is greatly improved. 3)After glass fiber reinforced, the reinforced plastic will not stress cracking, at the same time, the impact resistance of the plastic improves a lot. 4)After the glass fiber reinforcement, the glass fiber is a high strength material, which also greatly improves the strength of the plastic, such as: tensile strength, compression strength, bending strength, improve a lot. 5)After glass fiber reinforcement, due to the addition of glass fiber and other additives, the combustion performance of the reinforced plastics decreases a lot, most of the materials can not be ignited, it is a kind of flame-retardant material. Datasheet for reference Applications PA66's comprehensive performance is good, with high strength, good rigidity, impact resistance, oil and chemical resistance, abrasion resistance and self-lubricating advantages, especially hardness, rigidity, heat resistance and creep performance is better.
