PPA
PPA is a technical polyamide for custom components requiring load capacity and tailored sliding behaviour.
Typical applications
PPA is suitable for functional prototypes, sliding and guide elements, gears and custom assembly aids.
Why PPA?
The unfilled grade combines engineering stiffness with greater deformability than fibre-filled grades.
Performance profile
- Heat deflection temperature (HDT)
- up to 81 °C
- Hardness
- 82 Shore D
- Tensile strength
- up to 72 MPa
- Elongation at break
- up to 10.5 %
Ideas for your application
Mechanical engineering, device development and automation, for example guides, adapters and development parts.
Surface and appearance
An opaque surface with a visible, geometry-dependent layer structure.
Designing your part to fit
For gears and guides, allow sufficient material at load transitions. Radii and defined clearances help maintain a good fit over time.
Finishing and post-processing
Mating surfaces and holes can be post-processed. Final dimensions are checked in the agreed moisture condition.
