PP-LGF Among many composite materials, long glass reinforced polypropylene material (PP-LGF) has gained more popularity for its low price, excellent mechanical properties and environmental friendliness.Compared with short glass fiber reinforced polypropylene material (PP-SGF), PP-LGF has more advantages in strength, stiffness, warpage, fatigue resistance, notch impact strength and dimensional stability, so products produced with PP-LGF can further achieve weight and cost reduction. The length of PP-LGF particles produced by our company is generally 8mm~15mm, in which the content of glass fiber can reach 20%~60%, and the retained length of glass fiber in the particles can reach 1mm~3mm, compared with PP-SGF materials whose retained length of glass fiber is only 0.2mm~0.4mm, PP-LGF can guarantee the following characteristics due to the three-dimensional network structure of its internal fiber.  1. Low density: The use of long glass fiber reinforced composite material instead of steel is an effective way to reduce the weight of the product.  2. High strength: The composite material with modified resin and different length of fiber has high mechanical strength, good rigidity and impact performance, which can replace steel plate to make coverings or structural parts. 3. Low cost: The use of long glass fiber reinforced composite materials instead of metal materials can simplify the design of complex metal parts and achieve the purpose of forming complex parts at one time. 4. Impact resistance: The elastic deformation property of resin makes long glass fiber reinforced composite materials have certain function of absorbing collision energy, and have a large buffering effect on the impact of certain speed. 5. Corrosion resistance: The composite material has strong corrosion resistance, and its corrosion resistance to acid, alkali and salt is better than that of metal. 6. Beauty: most resins have good colorability, and can be made into various colors by adding masterbatch or spraying paint on the surface; through injection and molding, various irregular curvature shapes can be realized.

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.

HPP material It is made by polymerization of a single propylene monomer. The molecular chain does not contain ethylene monomer, so the regularity of the molecular chain is very high, so the crystallinity of the material is high and the impact performance is poor. In order to improve the brittleness of PP-H, fiber modification is used to improve the properties of PP-H. Advantages: Good strength. Disadvantages: poor impact resistance (brittle), poor toughness, poor dimensional stability, easy aging, long-term heat resistance and stability performance. HPP-LGF material 1. Long glass fiber belongs to high temperature resistant material, therefore, the heat resistance temperature of glass fiber reinforced PP is much higher than before without long glass fiber. 2. After adding long glass fiber, the mutual movement between polymer chains of plastic is limited, therefore, the shrinkage rate of glass fiber reinforced plastics decreases a lot, and the rigidity is greatly improved. 3. After long glass fiber reinforcement, PP plastic will not stress cracking, anti-impact performance improved a lot. 4. Long glass fiber is a high strength material, which also greatly improve the strength of PP, such as: tensile strength, compression strength, bending strength, improve a lot. 5. After adding long glass fiber, the combustion performance of PP plastic decreases a lot, and has a certain flame retardant effect. Short glass fiber (SGF) VS Long glass fiber (LGF) 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 (strength and rigidity) is increased by 0.5-1 times. Datasheet for reference Application Why choose Long glass fiber compounds? Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properties of engineering polymers, and increase the durability by forming long fibers to form a long-fiber-reinforced internal skeleton network.
