TPU introduction Thermoplastic polyurethane (TPU) elastomers are linear polymers formed by the copolymerization of hard and soft chain segments, which have physical properties such as tensile, abrasion and heat resistance, and elasticity similar to rubber. Thanks to the excellent product performance, the application fields of TPU are expanding, including daily consumer goods, construction, medical, military, automotive, agriculture and many other fields. New products and applications are also emerging, such as large-diameter hoses (shale gas extraction), charging cables for new energy vehicles, foamed TPU (ETPU) sports shoes midsoles prepared by supercritical foaming process, invisible braces, etc. Fiber reinforced modified TPU composites TPU has good impact resistance, but in some applications, high modulus of elasticity and very hard material is required. Glass fiber reinforced modification is a common technical means to improve the elastic modulus of the material. Through modification, thermoplastic composites with many advantages such as high elastic modulus, good insulation, heat resistance, good elastic recovery, good corrosion resistance, impact resistance, low coefficient of expansion and dimensional stability can be obtained. Long glass fiber VS Short glass fiber Compared with the short fiber, long fiber has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher toughness than short fiber, and the tensile strength is increased by 0.5-1 times. Thermoplastics VS Thermosets Thermosets: when heated for the first time, they can soften and flow, and when heated to a certain temperature, they produce a chemical reaction a cross-chain curing and become hard, this change is irreversible, after that, when heated again, they can no longer become soft and flow. Thermoplastic: thermoplastic resin is the main component, and various additives are added to form a plastic. Under certain temperature conditions, plastic can be softened or melted into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repeated is only a physical change. Advantages Thermosets: Thermoset plastics retain their strength and shape even when heated. This makes thermoset plastics ideal for producing permanent parts and large, strong shapes. In addition, these parts have excellent strength properties (despite their fragility) and do not lose significant strength when exposed to higher operating temperatures. Thermoplastics: Thermoplastics are the most widely used plastics and typically have high chemical and thermal resistance, as well as a high strength structure that is not easily deformed. It is made of thermoplastic resin as the main component with various additives.  Thermoplastic products have excellent electrical insulation, with very low dielectric constant and dielectric loss, suitable for high Frequency and high voltage insulation materials.

• 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.
