LFT-G® LGF50 HDPE Composite
The Composition of LGF50 HDPE
LFT-G® LGF50 HDPE is a 50% long glass fiber reinforced HDPE compound developed for lightweight structural components requiring high stiffness, strength, impact resistance and excellent environmental durability.
Material Composition
Matrix: High-Density Polyethylene (HDPE)
Reinforcement: 50% Long Glass Fiber (LGF)
Material Form: Long-fiber reinforced pellets
Primary Processing: Injection Molding
The HDPE matrix provides chemical resistance, moisture resistance and toughness, while the long glass fiber reinforcement significantly enhances the structural properties of the base resin.
Why LGF50 HDPE?
LGF50 HDPE is not simply a stronger version of conventional HDPE. Its main value comes from combining the characteristics of an HDPE matrix with the structural reinforcement of long glass fibers.
For applications where unfilled HDPE is too flexible, LGF50 HDPE provides a significant increase in stiffness and strength.
01
Compared with conventional short-glass-fiber compounds,
the long-fiber structure offers improved reinforcement efficiency and better suitability for components subjected to impact, cyclic loading and sustained mechanical loads.
02
Compared with metal,
LGF50 HDPE provides a lightweight thermoplastic solution with corrosion resistance and the ability to manufacture complex geometries through injection molding.
03
Compared with higher-cost engineering plastics,
the HDPE matrix provides an attractive combination of chemical resistance, low moisture absorption, toughness and structural reinforcement.
LGF50 HDPE: Key Features
- High Structural Stiffness：Provides higher rigidity for structural components compared with conventional HDPE.
- High Strength：Long glass fibers enhance load transfer and overall mechanical strength.
- Excellent Impact Resistance：Combines high rigidity with strong impact resistance for demanding applications.
- Chemical Resistance：HDPE offers excellent resistance to many chemicals, acids and alkalis.
- Low Moisture Absorption：Very low moisture absorption helps maintain stable performance in humid environments.
- Lightweight Structural Design：High reinforcement with relatively low density supports lightweight structural applications.
