What is GF40 PP UV Grade?
LFT-G® NG04V PP GF40 is a 40% long glass fiber reinforced Polypropylene composite with UV resistance performance Homo-polymer. This advanced glass reinforced plastic is engineered for superior outdoor durability and structural integrity. By reinforcing a polypropylene homopolymer with 40% long glass fiber and a specialized UV-stabilizer package, this reinforced polymer delivers exceptional mechanical strength that is maintained even after prolonged sun exposure. Unlike short fiber versions which offer limited strength, the interlocking long fiber network provides superior impact resistance and stiffness. This PP GF40 grade is ideal for automotive exterior parts, outdoor furniture, and sporting equipment where both performance and weatherability are crucial.

Processing Information
To achieve optimal performance and surface finish from LFT-G® PP GF40, precise control over the injection molding process is key. The higher 40% fiber loading requires careful management of screw speed, back pressure, and injection velocity to preserve the integrity of the long glass fiber network, which is fundamental to the material's superior strength and impact properties.

FAQ
1.What is the benefit of UV resistance in this PP GF40 grade?
A: The primary benefit is long-term durability for outdoor applications. The UV stabilizer package in our LFT-G® PP GF40 protects the polymer from degradation caused by sunlight, preventing brittleness and color fade over time.
2.How does this compare to standard PP GF40?
A: This grade offers all the high strength and stiffness of our standard PP GF40 material, but with the significant added benefit of long-term weatherability. It is specifically designed for parts that need to maintain both mechanical integrity and aesthetic appearance after prolonged outdoor exposure.
3.Can this composite be used for car exterior parts?
A: Yes, the enhanced UV stability of this reinforced polymer makes it an excellent choice for a variety of automotive exterior parts. Components such as mirror housings, rocker panels, and other trim pieces made from this LFT-G® grade will resist environmental stress cracking and fading.
