A FORMULATION STUDY OF LONG FIBER THERMOPLASTIC POLYPROPYLENE (PART 1): THE EFFECTS OF COUPLING AGENT, GLASS CONTENT RESIN PROPERTIES ON THE MECHANICAL PROPERTIES

摘要

The relationship between the resin and fiber properties in Polypropylene Long Fiber Thermoplastics is presented. The effects of glass content, Maleic anhydride grafted polypropylene additives (coupling agent) and melt flow of the resin are presented. Various samples of Polypropylene Long Fiber Thermoplastics pellets (PP GLFT) were compounded with various coupling agent loadings and using different melt flow homopolymer polypropylene resins. The glass content of the pellets was varied from 30% to 50%. The pellets were then molded and tested for normal mechanical properties. The results of the study are presented.
