30% LGF PP Compound Resin
LGF30 PP is a structural-grade engineering composite material made from high-performance polypropylene (PP) as the matrix, with 30% long glass fibers added. Through the long fiber impregnation and directional dispersion technology, the glass fibers form a continuous load-bearing framework within the resin matrix. Compared to traditional short fiber reinforced PP, it has a higher rigidity retention rate, better impact toughness, better dimensional stability and lower creep deformation.
LGF30 PP is a type of structural reinforcing thermoplastic composite material. Compared with conventional mineral-filled PP or short glass fiber PP, LGF30 PP compound resin has significant advantages in the "structural load-bearing capacity" dimension, and is particularly suitable for scenarios with complex forces, repeated impacts, and long-term loads.
The Material Structure System of LGF30 PP
Matrix resin system
- High-purity polypropylene (PP)
- Good fluidity stability
- Excellent chemical resistance
- Excellent electrical insulation performance
Long glass fiber reinforced system
Compared to traditional short glass fibers (generally less than 1mm), long glass fibers can maintain a higher effective length after molding, thereby resulting in:
- Three-dimensional enhanced skeleton
- Greater load dispersion capability
- A more effective shock absorption mechanism
- Lower risk of stress concentration

5
The long fiber network of LGF30 PP enables the material to maintain high strength under various loads such as stretching, bending and impact, and also ensures the material's stability under repeated loads and long-term static loads.
The strength and rigidity data of LGF30 PP are excellent. Under the premise of ensuring structural performance, the wall thickness can be reduced to achieve lightweighting, thereby lowering material and transportation costs.

FAQ
Q: How does the long-term creep behavior of LGF30 PP perform?
A: Compared with ordinary PP or short-fiber PP, LGF30 PP exhibits lower deformation under long-term static load conditions. The long-fiber framework can effectively disperse and withstand continuous stress, thus providing higher dimensional stability and long-term reliability in structural support components.
Q: Is the material suitable for high-temperature conditions?
A: The heat distortion temperature of LGF30 PP can typically reach 150°C or above (under 1.8 MPa conditions), which is significantly higher than that of ordinary PP. It is suitable for medium-high temperature applications, but is not suitable for environments where it exceeds its thermal stability limit for an extended period.
Q: Will the long glass fibers be cut during the processing?
A: Under normal injection molding conditions, the fibers will undergo a certain degree of shearing. However, by reasonably controlling the screw rotation speed, back pressure, and nozzle design, the effective fiber length can be maximally retained, ensuring that the performance is fully released.
