Tecatron® (Ensifide) PPS
PolyPhenylene Sulfide
| Tecatron ® PPS (formerly known
as Ensifide ®) 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.
As an unfilled PPS material, Tecatron® is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a lower-temperature replacement for PEEK. Tecatron® is off-white in color. Tecatron ® GF 40 (40% Glass Reinforced) This product is the most recognized filled grade of PPS. It offers better dimensional stability and thermal performance than unfilled Tecatron ® PPS and maintains its strength to above 425°F (220°C). Tecatron ® PVX (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. |
