PP Compound is made of polypropylene (PP) resin mixed with various additives and reinforcements in specific formulas to meet characteristics of each end product. Siddh Chemiplast offers a series of PP compounds, includ- ing: PP glass fiber compound (PP-GF) PP glass bead compound (PP-GB) PP talc powder compound (PP-TALC) PP BaSO4 compound (PP-BaSO4 PP conductive compound (PP-Conductive) PP flame retardant compound (PP-FR) PP compound for laser marking
Thanks to the use of glass fiber as the reinforcement, PP-GF compound increases stiffness, reduces shrinkage, improves impact strength and enhances heat resistance of end products.
