60 SHORE D POLYURETHANE ELASTOMER RoHS
BJB s MD Series of semi rigid, medium work time urethane elastomers exhibit great flexibility and excellent durability. These
tough, abrasion resistant systems easily process at room temperature. The MD Series is perfect for larger or more complex parts
and offers superior performance in many applications such as rollers, foundry tooling and high impact semi rigid parts. For faster
work times consider BJB s FD Series of elastomers.
