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.

Perguntas frequentes

P. A fibra de vidro longa e a injeção de fibra de carbono longa têm requisitos especiais para máquinas de moldagem por injeção e moldes?

R. Certamente existem requisitos. Especialmente a partir da estrutura de design do produto, bem como o bico do parafuso da máquina de moldagem por injeção e o processo de moldagem por injeção da estrutura do molde devem considerar os requisitos de fibras longas.

P. As causas e soluções para fibras flutuantes para produtos de fibra de vidro longa e fibra de carbono longa.

A. Devido à baixa temperatura do sol ou à baixa temperatura do molde e à baixa pressão de moldagem por injeção, a fibra de vidro e a resina podem não ser bem compatíveis e difundidas. A temperatura irregular do molde da superfície do molde causará o problema da fibra flutuante e pode ser resolvido aumentando a temperatura do sol, a temperatura do molde e a pressão de injeção.

Q. O PP reforçado com fibra de vidro longa reduzirá a tenacidade do material e aumentará a fragilidade. Existe alguma maneira de resolver este problema?

A. A fibra de vidro longa e a fibra de carbono longa aumentam muito o impacto e a resistência à tração do substrato.
