Rubber-Like PU
Rubber-Like
Rubber-Like is a rubber-like pu polyurethane — cast elastomer, pick shore a hardness per application. Typical values: 8 MPa yield, 1.1 g/cm³, rated to 80 °C. Available for Urethane casting at FabDigit.
Properties
Typical room-temperature values in the Shore A 60 condition. Metric first, imperial in gray. The bars show where Rubber-Like sits against the other 9 polyurethane 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.
