TPE
TPE is an elastomer polymer — rubber-like flexibility. Typical values: 5 MPa yield, 1.1 g/cm³, rated to 80 °C. Available for Injection molding at FabDigit.
Properties
Typical room-temperature values in the Shore A 30 to Shore A 90 condition. Metric first, imperial in gray. The bars show where TPE sits against the other 74 polymer grades in the catalog.

Property data is compiled from published supplier and standards handbooks and normalised for comparison; hardness values on non-Brinell scales are converted approximately for charting only. Manufacturability limits are FabDigit quote-engine defaults and may be relaxed by engineering review. Nothing on this page is a certification — request mill certs, CoC or material test reports with your order.
