PP fill Long glass fiber Advantages of glass fiber reinforced PP material in modified PP material. 1、The heat resistance temperature of glass fiber reinforced PP is much higher. 2、The shrinkage of glass fiber reinforced PP decreases a lot, and the rigidity is greatly improved. 3, glass fiber reinforced PP plastic, will not stress cracking, impact resistance improved a lot. 4、After glass fiber reinforced, the burning performance of PP plastic is reduced a lot. 5、After glass fiber reinforcement, the strength of PP is improved, such as: tensile strength, compressive strength, bending strength. The disadvantages of glass fiber reinforced PP material in modified PP material. 1、After glass fiber reinforcement, the transparency of the material decreases. 2、After glass fiber reinforced, the toughness of PP decreases and the brittleness increases. 3、After glass fiber reinforced, the hygroscopic property of PP is greatly enhanced, therefore, it should be dried when injection molding. 4、After glass fiber reinforcement, the melt viscosity of PP increases, the fluidity becomes worse, and the injection pressure increases a lot. 5、After glass fiber reinforcement, the fluidity of PP material is poor, and the injection temperature of reinforced plastic is increased by 10℃-30℃. 6、After glass fiber reinforced, attention should be paid to the surface corrosion treatment and surface hardness treatment of the equipment. 7、After glass fiber reinforcement, during the injection process, glass fiber can enter the surface of plastic products, making the surface of the products become rough. It is necessary to use the mold temperature machine to heat the mold when injection molding, so that the plastic polymer can enter the surface of the products and obtain a higher surface quality.

Does long glass fiber and long carbon fiber injection have special requirements for injection molding machines and molds? A. There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber. Q. The causes and solutions for floating fibers for long glass fiber and long carbon fiber products. A. Due to the low temperature of the sol or the low temperature of the mold and the low injection molding pressure, the glass fiber and the resin can not be well compatible and diffused. The uneven temperature of the mold surface mold will cause the floating fiber problem, and can be solved by increasing the sol temperature, mold temperature and injection pressure. Q. Long glass fiber reinforced PP will reduce the toughness of the material and increase the brittleness. Is there any way to solve this problem? A. Long glass fiber and long carbon fiber will greatly enhance the impact and tensile strength of the substrate.

PP filling Long glass fiber PP (polypropylene), as one of the general-purpose plastic materials, has a large production volume and low price, as well as excellent comprehensive performance, good chemical stability, and better molding and processing performance. However, the shortcomings of PP, such as low strength, low service temperature, low hardness, and poor low-temperature impact strength, have seriously limited its application areas. Therefore, engineers by adding glass fiber, calcium carbonate and other reinforcing materials in PP, and when the length of the glass fiber and other lengths exceed the critical size, the mechanical properties are improved by leaps and bounds! Long Glass Fiber Reinforced PP (LFT-PP) is a very typical thermoplastic composite material, which is generally a column of particles with a length of 12 mm to 25 mm and a diameter of about 3 mm. In these particles, the glass fibers have the same length as the particles, the content of glass fibers can vary from 20% to 70%, and the color of the particles can be matched according to customer requirements. PP-LGF advantages 1. longer fiber length, significantly improve the mechanical properties of the products. 2. high strength, good impact resistance, especially suitable for furniture, automotive parts. 3. high creep resistance, good dimensional stability, high precision parts molding. 4. excellent fatigue resistance. 5. better stability in high temperature and humid environment. 6. molding process fiber can be in the molding mold relative movement, fiber damage is small.
