Polyphenylene sulfide is an engineering plastic, commonly used today as a high-performance thermoplastic. PPS can be molded, extruded, or machined to high tolerances. With 40 percent glass fiber, PPS is an excellent cost-effective material. Its hardness, abrasion resistance, weld line integrity and other properties are better than most high-temperature thermoplastics. The design was inspired by the FontanaShowers design. Be sure, when it comes to new Bathroom Faucet, FontanaShowers is offering shape, finish and styles you're looking for. It comes complete with mounting accessories and installation instructions.
