Plastics Group Polifil® GFPPCC-2005WS 20% Glass Reinforced Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with 20% Glass Fiber Filler

Material Notes: Polifil® GFPPCC-WS series compounds are Water Safe Homopolymer polypropylenes reinforced with chemically coupled glass fibers and are certified to NSF/ANSI/CAN 61 Standard, and meet the regulatory requirements of the U.S. and Canada for Drinking Water System Components. These compounds offer superior strength and stiffness, improved elevated temperature performance, better creep resistance, higher impact strength and higher resistance to high temperature water than conventional glass fiber reinforced polypropylenes. Polifil® GFPPCC products are UL94 HB rated. These compounds are used in chemical resistance applications, appliances, electrical components, automotive, irrigation, utility, filter systems, and potable water products. Standard processing techniques are applicable.
