What application areas does long glass fiber PP flow to?
  In recent years, long glass fiber modified PP has been extremely popular in the raw materials of fiberglass industry. Long glass fiber reinforced PP material is cheap and has excellent performance no less than that of reinforced engineering plastics. The combination of these two points shows the advantages of high cost performance and is widely favored by the industry.

  At present, these manufacturers have invested a lot of manpower and material resources in the production, research and development and market development of this type of material.
PP material
  As one of the general plastic materials, PP Glass Fiber Reinforced has excellent comprehensive properties, good chemical stability, good molding performance and relatively low price; however, PP has low strength, modulus, hardness, poor low temperature impact strength, and molding. The disadvantages of large shrinkage and easy aging.

  Generally speaking, the tensile strength of PP material is between 20M~30MPa, the bending strength is between 25M~50MPa, and the bending modulus is between 800M~1500MPa. Especially the high modulus reinforced material Fiberglass ECR Roving, durable quality guarantee.Therefore, it is modified so that it can be adapted to the needs of the product. Today, each modified PP has a large number of applications in the field of household appliances and vehicles.

long glass fiber
  Glass fiber rovng is an inorganic non-metallic material with excellent performance. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness, resistance Poor abrasiveness. One of the main uses of glass fiber is the reinforcement of composite materials. Long glass fiber generally refers to glass fiber with a length of more than 10mm.
Long glass fiber reinforced PP plastic
  Long glass fiber reinforced PP plastic refers to a modified PP composite material with a glass fiber length of 10 to 25 mm, and a three-dimensional structure with a glass fiber length greater than 3mm Fiberglass Chopped Strand . As an automotive module carrier material, the material can not only effectively improve the rigidity, impact strength, creep resistance and dimensional stability of products, but also can make complex automotive module products.
Why do some fields use long glass fiber reinforced PP instead of short glass fiber reinforced PP?
Chopped Glass Fiber Thermoplastic Composites, LFT has the following advantages:
• Longer fiber length significantly improves the mechanical properties of the product.
• High specific stiffness and specific strength, good impact resistance, especially suitable for the application of auto parts.
• Improved creep resistance, good dimensional stability, and high part forming precision.
• Excellent alkali resistance, such as long fiber AR-glass Fiberglass Roving.
• Better stability in high temperature and humid environments.
• During the molding process, the fibers can move relatively in the molding die, and the fiber damage is small.
Where is long glass fiber reinforced PP often used?
Auto industry
Front-end modules, door modules, shifting mechanisms, electronic accelerator pedals, instrument panel skeletons, cooling fans and frames, battery brackets, bumper brackets, underbody protection panels, sunroof frames, etc., are used to replace reinforced PA or metal materials. The application of glass fiber of Hebei Yuniu Fiberglass Manufacturing Co., Ltd. in these fields has been greatly promoted, and the current consumption is 20,000T/Y.
Appliance industry
Washing machine drum, washing machine tripod, one brush machine drum, air conditioner fan, Fiberglass Spray Up Roving for sanitary ware, etc. used to replace short glass fiber reinforced PA, APS or metal materials.
Communication, electronics, electrical appliances industry
High-precision connectors, igniter components, coil shafts, relay bases, microwave oven transformer coil frames/frames, electrical connectors, solenoid valve packages, scanner components, etc. in the communication electronics industry.

Power tool casings, water pump or water meter casings, impellers, bicycle frames, snowboards, ground motorcycle pedals, military/civilian safety helmets, safety shoe toe caps, etc., used to replace Fiberglass Chopped Strands reinforced PA, PPO, etc.
