PLA (Polylactic Acid) is a semicrystalline thermoplastic polyester. It is derived from renewable sources and is therefore classified as a bioplastic.

Polyphthalamide (PPA) is a semicrystalline, aromatic polyamide. It is in the polyamide, or nylon, family. Compared to Nylon 6/6, it is stronger, stiffer, less sensitive to moisture, and has higher thermal capabilities. In addition, it has significant resistance to chemical fatigue and mechanical creep.

With its unique balance of strength, barrier performance, and stability, MXD6-LGF is the ideal solution for demanding applications.

PLA & LGFPLA – Eco-Friendly and Reinforced Bioplastics PLA (Polylactic Acid) is a non-natural polyester and one of the most promising "green plastics." Known for its biocompatibility, biodegradability, and high mechanical strength, PLA can be completely degraded by microorganisms into CO₂ and water, making it non-toxic and environmentally friendly. PLA offers mechanical properties similar to polypropylene, while providing the gloss, clarity, and processability of polystyrene. With a lower processing temperature than polyolefins, PLA can be molded via injection molding, extrusion, blow molding, spinning, and other general plastic processes. Its applications range from disposable packaging and fibers to nonwovens, and extend to medical, chemical, pharmaceutical, and 3D printing industries. Long Glass Fiber Reinforced PLA (LGFPLA) Glass fiber is an inorganic non-metallic material with excellent insulation, heat resistance, corrosion resistance, and mechanical strength. When used to reinforce PLA, it creates Long Glass Fiber PLA (LGFPLA), a high-performance thermoplastic composite with glass fibers 10–25mm long, forming a 3D structure for superior strength and stability. LGFPLA is available as columnar pellets, typically 12mm (for injection molding) or 25mm (for compression molding) in length, with glass fiber content from 20% to 60%. Colors can be customized to match client requirements. Advantages of LGF vs SGF (Long Fiber vs Short Fiber PLA) Longer fiber length improves mechanical properties and part durability. High specific stiffness and strength, with excellent impact resistance — ideal for automotive parts. Improved creep resistance and dimensional stability for precise molding. Outstanding fatigue resistance and long-term reliability. Stable performance in high temperature and humid environments. Minimal fiber damage during molding due to fiber mobility within the mold.

HDPE Plastic | Long Glass Fiber Reinforced HDPE What is HDPE? High Density Polyethylene (HDPE) is a granular thermoplastic material that is non-toxic, odorless, and highly crystalline (80% - 90%). It has a softening point of 125–135°C and can be used at temperatures up to 100°C. Compared with Low-Density Polyethylene (LDPE), HDPE has superior hardness, tensile strength, creep resistance, wear resistance, electrical insulation, toughness, and cold resistance. It also offers excellent chemical stability, being insoluble in any organic solvents at room temperature and resistant to corrosion from acids, alkalis, and various salts. Long Glass Fiber Reinforced Plastics (LGF) Long glass fiber reinforced plastics (LGF plastics) are created by adding long glass fibers and other additives to pure plastics. This reinforcement significantly improves the material's mechanical and thermal properties, making it suitable for structural and engineering applications. LGF plastics are commonly used with materials such as PP, ABS, PA66, PA6, HDPE, PPA, TPU, PEEK, PBT, and PPS. Advantages of Long Glass Fiber Reinforced Plastics Increased heat resistance: Glass fibers improve the high-temperature performance of plastics, especially in nylon-based materials. Reduced shrinkage and increased rigidity: Fiber reinforcement restricts polymer chain movement, improving dimensional stability. Improved impact resistance: Reinforced plastics resist stress cracking and have higher toughness. Enhanced strength: Tensile, compression, and bending strength are significantly improved due to the high-strength glass fibers. Flame retardancy: Addition of fibers and additives reduces flammability, making most reinforced plastics non-ignitable.

PBT Plastic | Long Glass Fiber Reinforced PBT (PBT-LGF) What is PBT? Polybutylene terephthalate (PBT) is a semi-crystalline engineering thermoplastic polyester. It is produced via polycondensation of 1,4-butylene glycol and terephthalic acid (PTA) or dimethyl terephthalate (DMT), forming a milky white translucent to opaque resin. PBT exhibits excellent mechanical strength, chemical resistance, thermal stability, and electrical insulation properties, making it ideal for demanding engineering applications.

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.

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.
