Clear Rubber-Like vs Rubber-Like
Polyurethane · grade comparison
Clear Rubber-Like and Rubber-Like are both polyurethane grades, both rubber-like pu. Rubber-Like is the stronger of the two: tensile strength 16 MPa (2.32 ksi) against 5 MPa (0.725 ksi) for Clear Rubber-Like, about 3.2 times as much. Rubber-Like is the more ductile: elongation 520% versus 180% for Clear Rubber-Like, and Rubber-Like is harder (16 Shore D vs 14 Shore D). Clear Rubber-Like is stiffer (0.01 GPa vs 0 GPa) and Rubber-Like runs hotter in service (80°C vs 65°C continuous). On the shop floor, Rubber-Like machines more easily (25 vs 15 out of 100), Rubber-Like welds better (poor vs not recommended), and Rubber-Like sits in a lower cost tier (budget, $) than Clear Rubber-Like (standard, $$).
Rubber-LikeChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Clear Rubber-Like vs Rubber-Like: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polyurethane grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Clear Rubber-Like vs Rubber-Like — frequently asked
Is Rubber-Like stronger than Clear Rubber-Like?
Yes. Rubber-Like has a typical tensile strength of 16 MPa (2.32 ksi) against 5 MPa (0.725 ksi) for Clear Rubber-Like — about 3.2 times as much.
Which is cheaper, Clear Rubber-Like or Rubber-Like?
Rubber-Like is the lower-cost material: it sits in the budget tier ($) while Clear Rubber-Like is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Clear Rubber-Like or Rubber-Like?
Rubber-Like, by a small margin. Both rate poor for machinability — 25/100 against 15/100 for Clear Rubber-Like; for welding the order is Rubber-Like first (poor, 15/100) then Clear Rubber-Like (not recommended, 5/100).
