Distributor of Ryton Plastic in Sheet, Rod, Bar and Brushing
 PolyPhenylene Sulfide (PPS) offers the broadest resistance
to chemicals of any advanced engineering plastic.
They have no known
solvents below 392°F (200°C) and are inert to steam, strong bases, fuels and acids.
Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components.

40% Glass Reinforced
This product is the most recognized filled grade of PPS. It
offers better dimensional stability and thermal performance than unfilled
Techtron ® PPS and maintains its strength to above 425°F (220°C).

Bearing Grade
Bearing grade PPS is internally lubricated and carbon fiber reinforced
offering a low coefficient of thermal expansion and uncompromised chemical
resistance. It is well suited for thrust or wear applications or when an
electrically conductive material is required.
