Fortron PPS

Fortron® polyphenylene sulfide (PPS) is often chosen over metals and thermosets, it’s a dimensionally stable, hard and rigid polymer that withstands temperatures to 200°C.  It has excellent chemical, creep and moisture resistance and is flame retardant.

Product Properties      

• Service temperature up to +240 °C 
• Very good resistance to chemicals and solvents
• Very hard and rigid
• Very low moisture absorption
• Inherently flame retardant (UL 94 V-0, some grades 5VA)
• Suitable for lead-free soldering
• Excellent creep resistance even at elevated temperatures

Fortron Linear PPS Offers Superior Properties vs. Branched and Semi-Linear PPS

• Toughness
• Outperforms semi-linear by 10−30%, branched by 25−45%
• Strength
• Especially at knit lines – beats semi-linear by 20−30% and branched by 85−170%
• Colorability (Available in a variety of standard colors; branched only available in brown and black. Note - cannot “color-match”.  Light colors will darken with heat / light exposure; dark colors lose gloss –not ideal for “appearance” parts.
• Processing Consistency
• More consistent viscosity vs. branched or semi-linear
• Broader viscosity range
• Wider available product offerings for blow-molding / extrusion
