LFT-G® LGF40 PP LFT Polypropylene For Auto Part

The PP LGF40 material has become increasingly popular in the industry, especially for parts that require high durability and strength. LFT-G® PP LGF40 stands for Polypropylene Long Glass Fiber 40%. This means that the material is made up of 40% long glass fiber and 40% polypropylene. The long glass fibers are what give the material its strength and durability, while the polypropylene provides flexibility and resistance to heat and chemicals.

Through the effect of different lengths of granules on the mechanical properties of glass fiber reinforced polypropylene composites, it was found that the impact strength of the composites increases with the increase of the original length of glass fibers (many experiments show that the fiber length in 10-12mm performance has better), this is due to the increase in fiber length, the probability of the fiber shear and fracture in the impact process increases, which will absorb more impact This is due to the fact that as the fiber length increases, the probability of fiber shear and fracture increases during the impact process, which will absorb more impact energy and thus enhance the ability of the composite material to resist impact.

Long glass fibers have excellent properties such as high temperature resistance, high strength, high impact energy absorption, low water absorption, good processability, inexpensive, and good bonding with resin. Commonly used LFTPP is a composite material of long glass fibers and polypropylene, which combines the advantages of glass fibers and polypropylene, and can effectively enhance the tensile and impact strength of polypropylene materials, as well as enhance the dimensional stability of PP materials, which has a very good prospect of application in automotive lightweight technology.

The matrix material of LFT composites in automotive industry is usually polypropylene(LFT PP Composite), which is widely used in automotive industry with obvious weight reduction effect, mainly used for bumpers, pedals, hoods, floors, guards, spare tire racks, etc., which can reduce weight by more than 20% compared to the original material, and reduce the cost of the material by more than 20%, which is a very good application of automotive light weighting and low-cost.

Xiamen LFT-G® Ltd has prepared LFT-PP pellets with 20%, 30%, 40% and 50%-70% glass fiber mass fractions using an LFT test line and molding equipment, and has successfully applied pellets with a 40% glass fiber mass fraction to automotive wing panels.
