Polypropylene microfoam has a unique "sandwich" structure, which consists of a dense surface layer and a fine and uniform core layer, which can significantly reduce the weight of the part and achieve weight reduction. It has been found that glass fiber has a large aspect ratio and a large surface area, and can be a cell nucleation point. It is an ideal cell nucleating agent, which imparts fine and uniform cells to polypropylene.
XIAMEN LFT COMPOSITE PLASTIC CO.,LTD. successfully developed micro-foamed long glass fiber reinforced polypropylene composite material with a cell diameter of about 70um. The product has the characteristics of fine and uniform cells, and realizes micro-foaming technology and long glass fiber. The perfect combination of technology. Uniform micropores eliminate residual stresses inside the material and improve the warpage of the fiberglass parts, resulting in a flatter, straighter and more dimensionally accurate product. The micro-foamed long glass fiber reinforced polypropylene composite material can not only meet the requirements of polypropylene micro-foaming lightweight, but also greatly improve the mechanical strength, impact resistance and heat resistance of the material, and can be widely used in automobile dashboards and front ends. Plastic parts inside and outside the car such as brackets, underframes and seats
