Xiamen, ChinaLong Glass Fiber Reinforced Polypropylene (PP-LGF) is a high-performance thermoplastic composite engineered for structural applications requiring superior strength, stiffness, and long-term durability.
By combining polypropylene with long glass fibers, PP-LGF delivers an optimal balance of lightweight design, mechanical performance, and cost efficiency—making it an ideal alternative to short glass fiber plastics and metal components.
Polypropylene (PP) is one of the most widely used general-purpose plastics, offering excellent chemical resistance, good processability, and competitive cost performance.
However, unmodified PP has limitations such as relatively low strength, stiffness, and impact resistance at low temperatures. To meet demanding structural requirements, PP is commonly reinforced with fibers.
Glass fiber is an inorganic, non-metallic reinforcing material known for high mechanical strength, heat resistance, corrosion resistance, and electrical insulation.
Long glass fiber typically refers to fibers longer than 10 mm, forming a stronger internal reinforcement network compared with short fibers.
PP-LGF is a modified polypropylene composite reinforced with long glass fibers ranging from 10 to 25 mm. After injection molding, the retained fiber length in the final part typically exceeds 3.1 mm, forming a stable three-dimensional structure.
This structure significantly enhances mechanical performance, creep resistance, and dimensional stability, even under long-term load or harsh environments.
Compared with short fiber reinforced thermoplastics, long fiber thermoplastic (LFT) materials provide clear advantages in load-bearing and structural applications.
PP-LGF is widely used in structural and semi-structural automotive components, replacing metal or reinforced polyamide materials.
Applications include front-end modules, door modules, gear shift systems, accelerator pedals, instrument panel carriers, cooling fan frames, battery carriers, bumper brackets, underbody protection plates, and sunroof frames.
Washing machine drums, triangular brackets, and air conditioner fans, replacing short glass fiber reinforced plastics or metal components.
High-precision connectors, relay bases, coil frames, solenoid valve housings, and scanner components.
Power tool housings, pump housings, impellers, bicycle frames, industrial pedals, safety helmets, and safety footwear components.
