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.

What is the PP materials?  Polypropylene (PP) is often referred to as the "steel" material of the plastics industry because it can be modified and customized to meet unique application requirements by adding additives to PP or by manufacturing it in unique ways. What is the Copolymer PP materials? Compared with PP homopolymer, copolymer polypropylene has improved optical properties, improved impact resistance, increased flexibility, lower melting temperature and thus also lower thermal fusion temperature; meanwhile, it is basically the same as homopolymer in terms of chemical stability, water vapor barrier properties and organ sensory properties. COPO-PP VS HOMO-PP COPO-PP Advantages: good overall performance, high strength, high rigidity, good heat resistance, good dimensional stability, excellent low temperature toughness (good flexibility), good transparency and good gloss. Disadvantages: Less heat resistant than homopolymer PP HOMP-PP Advantages: better strength. Disadvantages: poor impact resistance (more brittle), poor toughness, poor dimensional stability, easy aging, poor long-term heat stability performance. Both of them we can provide, just contact us if you need.
