Ensinger: First thermoformable PPS sheet
Ensinger/Penn Fibre has developed what it claims is a first: thermoformable PPS in sheet and roll form. The company says the crystalline material is suitable for thick- and thin-wall forming of parts requiring a high level of heat and chemical resistance, plus hardness and rigidity at elevated temperatures (melt point is 288 to 315 C), good electrical properties, inherent flame retardance, and dimensional stability. Target applications include fluoropolymer replacement, where the sheet can reduce material costs by at least 30%.
The monolayer sheet and roll grades are based on Fortron PPS from Ticona. The line includes neat and glass-reinforced versions and grades containing impact modifiers, tougheners, and other additives. Sheet and roll widths run to 48 in, and thicknesses are between 0.010 and 0.25 in. Optional backings of glass fiber, polyester fabric, and other materials that create a gluing surface are available.
