Food-contact compliant PPS for food machinery and potable water system parts.
Food-Grade PPS is a Food Grade grade within PPS (Polyphenylene Sulfide), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.
PPS grade compliant with food-contact regulations, suitable for food machinery and potable water system parts.
Food-Grade PPS grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.
Food-Grade PPS demonstrates the following core advantages in CNC machining and end-use applications.
The following are key process points when machining PPS (Polyphenylene Sulfide) material, to ensure part quality and machining efficiency.
PPS is relatively brittle; use sharp tools with positive rake angles and smaller depths of cut to prevent edge chipping at exit.
Glass-fiber/carbon-fiber-reinforced grades are highly abrasive; use diamond-coated (CVD) or PCD tools.
Air cooling or MQL is recommended; avoid coolant jet impact that can cause localized stress concentration.
Reinforced grades exhibit anisotropy; align machining paths with material flow direction and maintain consistent orientation across batch parts.
Besides Food Grade PPS, PPS (Polyphenylene Sulfide) offers several other grades with different characteristics. Click to view details.
