Thermoformable PPS Sheet

Magee Plastics Company has broken new ground in the use of polyphenylene sulfide (PPS) by developing commercial procedures for pressure-forming and vacuum-forming PPS sheet. This work was based on the use of Ensinger/PennFibre’s 1/8” PPS sheet, which is made with thermoformable Fortron® PPS resins from Ticona, the technical polymers business of Celanese AG.

The sheets used involved Fortron PPS unfilled, glassfilled and impact-improved thermoformable grades. These grades have high strength-to-weight ratios and continuous service temperatures up to 450°F (232°C) depending upon composition. Magee Plastics has completed its first commercial thermoformed PPS end use, which involved elements for a defense-related application.

Ensinger/PennFibre thermoformable PPS is sold as monolayer sheets. The company also offers five grades of sheet and rolls made from Fortron PPS for fabrication in widths to 48 inches (122 cm) and thicknesses between 0.01 and 0.25 inch (0.25-6.3 mm). Its PPS sheet is available with optional backings of glass fiber, polyester fabric and other materials that create a gluing surface for strong adhesion in multilayer structures.
