Is PPS right for the part?

Where PPS works, and where another plastic may suit

General guidance on how PPS behaves. If your drawing specifies a PPS grade, Ryton® or Techtron®, we machine to it.

Where it works

Chemicals
Resists almost all solvents, acids and alkalis.
Size
Takes on almost no water, so it holds close size.
Heat
Stays stiff at high temperatures, including in hot water.
Flame
Resists burning without added flame retardants.

Where another plastic may suit

If the part needs Often used instead
Impact PPS is brittle and can crack under knocks. These are tougher.
Strong oxidizing acids Strong oxidizing acids attack PPS. These resist them.
Lower cost Where the part doesn’t run hot or meet harsh chemicals, these machine well for less.

Precision in PPS

How we machine PPS

±0.002"–±0.005" On critical dimensions, depending on the plastic

PPS is stable, so it machines to close size. Its brittleness is what we control, at edges, thin walls and threads. We confirm the critical dimensions with your quote.

  1. Chipping

    PPS is brittle, so edges and thin walls can chip.

    We use sharp tools and light finishing cuts, and support thin sections.

  2. Glass-filled grades

    Glass wears cutting tools quickly.

    We use carbide or diamond tooling, so size holds across the run.

  3. Holes and threads

    Brittle plastic can crack at holes and threads.

    We drill and thread with care, then deburr every edge.

Grades

PPS grades

PPS comes unfilled, glass-filled and in bearing grades. Name the grade on your drawing, or tell us how the part is used and we’ll suggest one.

Grade Typically used for
Unfilled Insulators and general-purpose parts.
Glass-filled Stiffer, more stable structural parts.
Bearing grade Wear rings, bushings and other sliding parts.
PEEK When the part needs more toughness or higher heat. PEEK

All plastics we machine

PEEK is tougher and handles higher heat. PPS resists most of the same chemicals and costs less. If your drawing specifies one, we machine to it.

Both are brand names for PPS. If your drawing specifies a brand grade, we machine to it. CDS isn’t affiliated with the trademark owners.

Yes. We supply PPS sheet and rod, cut to size when you need it, through our material supply service.
