HPP 一般グレード充填 ガラス長繊維 LGF ポリプロピレン改質プラスチック強化材料

HPP素材

単一のプロピレンモノマーの重合によって作られます。分子鎖中にエチレンモノマーを含まないため、分子鎖の規則性が非常に高いため、材料の結晶性が高く、衝撃性能が劣ります。

PP-Hの脆性を改善するために、繊維改質によりPP-Hの特性を改善します。

メリット：強度が良い。

欠点：耐衝撃性（脆性）が低い、靱性が低い、寸法安定性が低い、老化しやすい、長期耐熱性と安定性能が低い。

HPP-LGF材質

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.

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. Performance is preserved in a wide range of environments.
