# TPE

## Material Info
### About

Thermoplastic Elastomer, or TPE, is an industry-standard flexible, rubber-like polymer material that is great for elastic end-use products. Printed using Selective Laser Sintering (SLS), a robust process that solidifies material layer-by-layer, TPE (SLS) parts are durable with high rebound properties and can include interlocking features. The material is skin contact safe with cytotoxicity (ISO 10993-5) and skin irritation and sensitization (ISO 10995-10) certifications.

### Color & Finishes

White

Available in Standard finish & Smooth

Black

Available in Natural finish

**Standard - Shotpeened**  
Our standard finish comes with a shotpeened smooth and slight glossy surface

**Smooth -By Request**  
Vapor-smoothed finish is available via our [sales team](/content/business/additive-manufacturing#contactsales/index.html). This finish has a smooth surface and slight shine, created using a physio-chemical process to vapor smooth the surface.
