Frequently Asked Questions
Is PPS safe for food contact?
Some PPS grades are FDA-compliant for repeated food contact. However, PPS can contain residual oligomers that migrate at high temperatures. For food processing equipment above 150°C, PEEK is preferred despite higher cost. For room-temperature chemical processing, PPS is acceptable and widely used.
