What is long glass fiber? Long glass fiber reinforced plastic is on the basis of the original pure plastic, adding long glass fiber and other additives, so as to improve the scope of use of materials. Why filling Long Glass Fiber? 1. After long glass fiber reinforcement, long glass fiber is a high temperature resistant material, therefore, the heat resistance temperature of reinforced plastics is much higher than before without long glass fiber, especially nylon plastics; 2. After long glass fiber reinforcement, due to the addition of long glass fiber, limited the mutual movement between polymer chains of plastics, therefore, the shrinkage rate of reinforced plastics decreases a lot, rigidity is greatly improved; 3. After long glass fiber reinforcement, the reinforced plastic will not stress crack, at the same time, the anti-impact performance of plastic is improved a lot; 4. After long glass fiber reinforcement, long glass fiber is a high strength material, which also greatly improves the strength of plastic, such as: tensile strength, compression strength, bending strength, improve a lot; 5. Long glass fiber reinforced after, due to the addition of long glass fiber and other additives, the combustion performance of reinforced plastics decreased a lot, most of the material can not ignite, is a kind of flame retardant material. Why choose Long Glass Fiber instead of Short Glass Fiber? Compared with short fiber reinforced thermoplastic composites, LFT has the following advantages: • Long fiber length, significantly improve the mechanical properties of products. • High specific stiffness and strength, good impact resistance, especially suitable for automotive applications. • Improved creep resistance, good dimensional stability, high parts forming accuracy. • Excellent fatigue resistance. • Better stability in hot and humid environments. • The fiber can move relatively in the molding mold during the molding process, and the fiber damage is small.

PP-LGF Glass fiber reinforced PP, usually, the tensile strength of PP material is between 20M~30MPa, bending strength is between 25M~50MPa, bending modulus is between 800M~1500MPa. If PP is to be used in engineering structural parts, it must be reinforced with glass fiber. Glass fiber reinforced PP, through glass fiber reinforced PP product mechanical properties can be multiplied or even several times the improvement. Specifically, the tensile strength reaches 65MPa~90MPa, the bending strength reaches 70MPa~120MPa, and the bending modulus reaches 3000MPa~4500MPa. Such mechanical strength can be completely comparable with ABS and enhanced ABS products, and it is more heat resistant. Glass fiber reinforced PP, general ABS and reinforced ABS heat resistance temperature between 80℃~98℃, and glass fiber reinforced PP material heat resistance temperature can reach 135℃~145℃. PP filling modification, adding a certain amount of inorganic minerals in PP, such as talcum powder, calcium carbonate, titanium dioxide, mica, etc., can improve rigidity, improve heat resistance and luster; Filling carbon fiber, boron fiber, glass fiber can improve the tensile strength; Adding flame retardant can improve flame retardant property. Filling antistatic agent, colorant, dispersant, etc. can improve the antistatic property, colorability and fluidity, etc.; Filling nucleating agent can speed up the crystallization speed, increase the crystallization temperature, form more and smaller spherical crystals, thus improving the transparency and impact strength. Therefore, the filler has a significant effect on improving the performance of plastic products, improving the plastic molding processability and reducing the cost. Application As one of the four general plastic materials, PP has excellent comprehensive performance, good chemical stability, better molding performance and relatively low price; But it also has the strength, modulus, hardness is low, low temperature impact resistance strength is poor, forming shrinkage, easy aging and other shortcomings. Therefore, it must be modified so that it can adapt to the demand of the product. The modification of PP material is generally through adding mineral reinforcement toughening, weather resistance modification, glass fiber reinforcement, flame retardant modification and super toughness modification, and each kind of modified PP has a large number of applications in the field of household appliances. Glass fiber reinforced PP, can be used to make refrigerators, air conditioning refrigeration machines such as axial flow fans and cross flow fans. In addition, it can also be used to manufacture the inner drum of high speed washing machine, wave wheel, belt wheel to adapt to its high requirements on mechanical properties, for the rice cooker base and handle, electronic microwave oven and other places with high requirements on temperature resistance. Glass fiber reinforced PP. Ordinary short glass fiber reinforced PP, because the glass fiber contains short, easy warping, low impact strength, easy deformation when heated, long glass fiber can overcome the above defects of short glass fiber, and the product has a better surface, higher temperature, higher impact strength, can be used in refrigerators and kitchen appliances with high heat resistance. Glass fiber reinforced PP is on the basis of the original pure PP, adding glass fiber and other additives, so as to improve the scope of use of materials. Generally speaking, most glass fiber reinforced materials are used in the structural parts of the product, which is a kind of structural engineering materials.
