MATERIAL FOR MAKING LONG FIBER FILLED THERMOPLASTICS WITH IMPROVED ADDITIVE EVENNESS AND PHYSICAL PROPERTIES
摘要
<p>A material and method for making long fiber filled thermoplastics with improved additive evenness and physical properties that includes a fiber-filled thermoplastic resin and a coating layer that contains the one or more additives to eventually be dispersed in the molded article. The coating layer is added in a manner such that the coating does not substantially intermix with the thermoplastic resin to form the long fiber-filled thermoplastic material. The long fiber-filled thermoplastic material may then formed into a molded article using the long glass fiber-filled thermoplastic material. Since the long fiber-filled thermoplastic material is not formed into pellets prior to formation into the article, the problems associated with prior art methods regarding dispersion of the additives are avoided and the resulting molded article has improved additive evenness and characteristics as compared to prior art molded articles formed from a dry blend of pellets.</p>
