Shanghai Daoqin Plastics Co., Ltd.

         glass fiber reinforced plastics is in has pure plastics upper, add glass fiber and its it additives, from improve/increase material use scope/range.

         generally 说, large separation glass fiber reinforced material more use in product structure parts upper, is types structure engineering material;如: PP ABS PA66 PA6 PC POM PPO PET PBT PPS

         advantages:

        1. glass fiber reinforced rear, glass fiber (GF) is high temperature resistance material, therefore, reinforcement plastics heat resistant temperature degree ratio add glass fiber (GF) front improve/increase very more, especially is nylon type plastics;

        2. glass fiber reinforced rear, due to glass fiber (GF) add 入, made plastics polymer/macromolecule versus 互移动, therefore, reinforcement plastics shrinkage rate decline very more, rigid property large large improve/increase;

        3. glass fiber reinforced rear, reinforcement plastics 不会应 force cracking, meanwhile, plastics impact resistant property can improve/increase very more;

        4. glass fiber reinforced rear, glass fiber (GF) is high strength material, from large plastics strong/high degree, 如: tensile strength, pressure shrink strong/high degree, flexural strength, improve/increase very more;

        5. glass fiber reinforced rear, due to glass fiber (GF) and its it additives add 入, reinforcement plastics property can decline very more, large separation material can 点燃, is types flame retardant material.

         disadvantages:

        1. glass fiber reinforced rear, due to glass fiber (GF) add 入, add glass fiber (GF) front is transparent, 都会变 formed transparent;

        2. glass fiber reinforced rear, has plastics tough property reduce, property increase;

        3. glass fiber reinforced rear, due to glass fiber (GF) add 入, has material melt viscosity increase large, flow property 变差, injection molding pressure ratio add glass fiber (GF) need increase very more;

        4. glass fiber reinforced rear, due to glass fiber (GF) add 入, flow property 差, is positive injection molding, has reinforcement plastics injection molding temperature degree need ratio add glass fiber (GF) front improve/increase 10℃-30℃;

        5. glass fiber reinforced rear, due to glass fiber (GF) and additives add 入, reinforcement plastics wet property can large add strong/high, pure plastics water 也会变 吸 water, therefore, injection molding need dry.
