Abstract: The present invention relates to a high melt flow thermoplastic resin filled with long fibers, such as long glass fibers, stainless steel fibers, carbon fibers, aramid fibers, or other like fibers, and having high melt flow properties. The high melt flow properties of the thermoplastic resin contribute to its ease of production, allowing for the production of long fiber-reinforced thermoplastic compositions having good dispersion and wet-out in the pellet and molded article, and characterized by low levels of loose fiber in the pellet and/or compound. Although any concentration of fibers may be present in the fiber-reinforced thermoplastic composition, the high melt flow thermoplastic resins are especially suitable for high concentrate long glass fiber-reinforced thermoplastic compositions.

Abstract: Malleable thermoplastic composite materials are provided. More specifically, malleable thermoplastic composite materials made from thermoplastic polymers having low molecular weight and particulate material are provided for malleable composites having high compression set. Alternatively, malleable composite blends of two or more thermoplastic polymers are provided wherein at least one thermoplastic polymer has a low molecular weight. Further, the malleable thermoplastic composites may be blended with high specific gravity particulate material to form high specific gravity composites that exhibit malleable characteristics.
