Our Homopolymer Polypropylene Long Glass Fiber Reinforced Material delivers excellent stiffness, structural strength, and dimensional stability — all while keeping weight and cost low. This material is specifically developed for injection-molded parts that demand rigidity and long-term durability.

Our high-performance homopolymer PP long glass fiber composite offers exceptional high strength and durability, making it an ideal solution for demanding industrial applications and automotive components. 

This nature is not lost when they are combined with fiberglass. PP-GF Compound plastic is not only light but also very durable. Therefore, they are suitable in industries such as automobiles, aerospace, heavy industry,...

HPP is Homopolymer polypropylene. These processes produce homopolymers for several industries including: automotive, packing, medical, consumer goods, and food containers. Within these industries, the homopolymers' corrosion resistance makes them ideal for containers, tanks, and pipes. Its dimensional stability allows it to be used for gears and bearings. 

Polypropylene, also known as PP or polypropene, is a polyolefin or saturated polymer. It is a low-density thermoplastic with good resistance to heat. Other characteristics of PP include: chemical resistance, elasticity, toughness, fatigue resistance, and electrical insulation capability. 

The modified polypropylene material reinforced by glass fiber has a series of advantages, such as light weight, high modulus, high specific strength, low coefficient of thermal expansion, high temperature resistance, heat shock resistance, corrosion resistance, good vibration absorption, etc., and can be applied to auto parts such as automobile sub-instrument assembly.

Glass fiber improves the tensile strength, high bearing capacity and temperature stability of the material. They are suitable for use in heavy industries.

• Lightweight alternative to metal and reinforced PA • Excellent impact strength and fatigue resistance • Ideal for structural automotive and industrial components PP Long Glass Fiber Reinforced (LFT-PP) Polypropylene (PP) is one of the most widely used general-purpose plastics due to its large production volume, competitive cost, excellent chemical resistance, and good processing performance. However, conventional PP materials have limitations such as relatively low strength, low heat resistance, limited stiffness, and poor low-temperature impact resistance. To overcome these limitations, reinforcing fillers such as glass fiber or calcium carbonate are added to PP. When the reinforcing fibers exceed a critical length, the mechanical properties of the composite can be significantly improved. Long Glass Fiber Reinforced Polypropylene (LFT-PP) is a high-performance thermoplastic composite material. The pellets are typically cylindrical with a length of 12–25 mm and a diameter of approximately 3 mm. The glass fibers inside the pellets maintain the same length as the pellet itself, which greatly enhances structural performance. The glass fiber content usually ranges from 20% to 70%, and the material color can be customized according to customer requirements. Advantages of PP-LGF 1. Long fiber structure significantly improves mechanical strength and stiffness. 2. High impact resistance, ideal for automotive and structural applications. 3. Excellent creep resistance and dimensional stability for precision parts. 4. Outstanding fatigue resistance, suitable for long-term load-bearing components. 5. Stable performance under high temperature and high humidity environments. 6. Reduced fiber breakage during molding, allowing better retention of fiber length and performance. Long Glass Fiber vs Short Glass Fiber Typical Applications Automotive Industry: front-end modules, door modules, gearshift components, electronic accelerator pedals, instrument panel carriers, cooling fan frames, battery trays, bumper brackets, underbody shields, and sunroof frames. LFT-PP is often used to replace reinforced PA or metal components. Home Appliances: washing machine drums, triangular brackets, air-conditioner fan components, and other structural parts, replacing short-fiber reinforced PA, ABS, or metal materials. Electronics & Electrical: high-precision connectors, ignition system components, coil bobbins, relay bases, transformer coil frames, electrical connectors, solenoid valve housings, and scanner components. Other Industries: power tool housings, pump housings, water meter housings, impellers, bicycle frames, skis, locomotive pedals, safety helmets, and protective equipment.
