PP Long Glass Fiber Reinforced Composite (PP-LGF)
Long glass fiber reinforced polypropylene (PP-LGF) has become one of the most popular lightweight composite materials due to its low cost, excellent mechanical properties, and environmental advantages.
Compared with short glass fiber reinforced polypropylene (PP-SGF), PP-LGF offers superior:
-
Strength and stiffness
-
Fatigue resistance
-
Impact resistance
-
Warp resistance
-
Dimensional stability
These advantages allow manufacturers to achieve lightweight designs while reducing production costs.
The PP-LGF pellets produced by our company are generally 8–15 mm in length, with glass fiber content ranging from 20% to 60%.
The retained fiber length inside the pellets can reach 1–3 mm, significantly longer than conventional PP-SGF materials (0.2–0.4 mm).
Due to the internal three-dimensional fiber network structure, PP-LGF provides the following advantages:
1. Lightweight Performance
Replacing metal with long glass fiber composites effectively reduces product weight.
2. High Strength & Rigidity
Excellent mechanical strength and impact performance make it suitable for structural applications.
3. Cost Reduction
Complex parts can often be molded in one step, simplifying manufacturing processes.
4. Excellent Impact Resistance
The material absorbs impact energy efficiently and provides effective buffering performance.
5. Corrosion Resistance
Outstanding resistance to acids, alkalis, and salts compared with traditional metals.
6. Design Flexibility
Supports customized colors and complex injection molded shapes.
