Relleno largo de fibra de vidrio Muestra de plástico personalizada de color natural de polipropileno

Información del Producto

plastico pp

Como uno de los materiales plásticos generales, el PP tiene excelentes propiedades integrales, buena estabilidad química, mejor rendimiento de moldeo y precio relativamente bajo. Pero el PP tiene las desventajas de baja resistencia, módulo, dureza, resistencia al impacto a baja temperatura, contracción de formación, fácil envejecimiento, etc.

En términos generales, la resistencia a la tracción del material PP está entre 20M y 30MPa, la resistencia a la flexión está entre 25M y 50MPa, y el módulo de flexión está entre 800M y 1500MPa. Por ello, se modifica para que se adapte a la demanda del producto. Hoy en día, cada tipo de PP modificado tiene un gran número de aplicaciones en el campo de los electrodomésticos y vehículos.

fibra de vidrio larga

It is a kind of inorganic non-metallic material with excellent performance. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittle and poor wear resistance. One of the main uses of glass fiber is to reinforce composite materials. Long glass fiber generally refers to the length of more than 10mm glass fiber.

PP-LGF

Long Glass Fiber reinforced PP plastic refers to the modified PP composite material which contains the glass fiber length between 10 and 25mm. After injection molding and other processes, the three-dimensional structure of the glass fiber length is larger than 3.1mm. It is also called Long Glass Fiber polypropylene, or LGFPP.

The material can not only effectively improve the rigidity, impact strength, creep resistance and dimensional stability of the product, but also can make complex products.

Why use LGF instead of SGF

Compared with short fiber reinforced thermoplastic composites, LFT has the following advantages:

• Long fiber length, significantly improve the mechanical properties of products.

• High specific stiffness and strength, good impact resistance, especially suitable for automotive applications.

• Improved creep resistance, good dimensional stability, high component forming accuracy.

• Excellent fatigue resistance.

• Better stability in hot and humid environments.

• The fiber can be relatively moved in the molding mold during the molding process, and the fiber damage is small

Product application
