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.
