| BJB’s FD Series of semi rigid, fast reacting urethane elastomers exhibit great flexibility and excellent durability. These tough, abrasion resistant systems easily process at room temperature and range in hardness from 45 Shore D to 70 Shore D. The FD Series offers superior performance in many applications such as rollers, foundry tooling and high impact semi rigid parts. For longer work times consider BJB’s MD Series of elastomers. RoHS/REACH compliant User friendly 2:1 ratio Ideal for cartridge dispense High tensile and tear strength Exceptional abrasion resistance Cures at room temperature&& |
