PP-LGF granules

【 Main ingredients 】
Contains long glass fiber and polypropylene resin, glass fiber compatibilizers, antioxidant additives and other additives.

【 Product features 】

1. It has excellent mechanical properties, which can effectively improve the rigidity, impact strength, creep resistance and dimensional stability of products.
2. Compared with ordinary glass fiber reinforced polypropylene, it has improved fluidity, can be integrated with a variety of parts and has a thinner forming thickness.
3. The enhancement of long glass fiber and the addition of high crystalline polypropylene resin make the material have better durability and reliability, and high temperature fatigue strength.
4. The ultra-low viscosity components form a thick plastic layer on the surface of the product, which can prevent the glass fiber from being exposed to the surface of the product, beautify the appearance, and eliminate the process of treating the surface of ordinary glass fiber reinforced plastics with paint.
5. According to different functional requirements, can be customized general grade, flame retardant grade, toughened grade, heat resistant grade, anti-UV grade, high surface grade and other professional performance
6. LFT particles with glass fiber content of 10%, 20%, 30%, 40%, 50% and 60% can be customized according to different requirements
7. According to the requirements can be customized black, natural color, yellow, green, gray and other color particles

【 Technical index 】

1. Glass fiber length: usually about 10mm to ensure that the glass fiber length in the product is more than 3.1mm.
2. Bending modulus, bending strength, impact strength and other mechanical properties: the same performance as glass fiber felt reinforced polypropylene (GMT).
3. Fluidity: 30% higher than ordinary glass fiber reinforced polypropylene (FGPP).

【 Application field 】
Widely used in the automotive field, such as automotive front-end modules, door modules, instrument panels, body bottom components, etc. It can also be used in electronic and electrical parts, sports equipment, packaging parts, tools, furniture and other fields.

【 Usage method 】

1. Injection molding: Long glass fiber reinforced polypropylene particles can be made into products of various shapes by injection molding process. During the injection molding process, it is necessary to pay attention to improving the geometry of the screw, such as deepening the screw groove, widening the screw tooth spacing, optimizing the screw, and expanding the hot run, so that the glass fiber reinforced resin can flow gently, reduce the high shear force in the plasticizing process, and reduce the length of the glass fiber.
2. Extrusion molding: suitable for the production of some specific extrusion products.

【 Note 】

1. Storage conditions: Should be stored in a dry, ventilated environment, avoid direct sunlight and humidity, to prevent the material from moisture or other pollution.
2. Processing temperature: According to the specific production process and equipment, the processing temperature is set reasonably to ensure the performance and molding quality of the material.
3. Mold design: When designing the mold, it is necessary to consider the fluidity of the material and the length of the glass fiber to ensure the quality and performance of the product.
4. Creep resistance: under high temperature and long-term low load conditions, the material will not produce significant creep, but the specific use environment still needs to be evaluated according to the actual situation.
5. Product design: Reasonable design for the generated stress to partially offset some drawbacks that may be caused by fiber orientation
