PPS Plates

Type	Material / Grade	Color	Operating Ambient Temperature
NPPS	PPS / Standard	Natural Color	Ambient Temperature ~ 190°C
NPMS	PPS / Abrasion Resistance Grade - Sliding	Blue	Ambient Temperature ~ 220°C

  PPS Standard Type generates an oxide film on the surface and the color turns to brown when it is exposed to light and heat (direct sunlight, fluorescent light, mercury lamp and high-temperature atmosphere) for long hours. However, it changes little in mechanical properties and physical properties.

   Material: PPSPolyphenylenesulfide
