Select the correct elastomers based on operating environment and final product properties required. The combination of high quality base polymers and chemicals supply a wide range of effective rubber compounds. These specially designed compounds allow us to meet the most stringent standards. The table shows a selection of Elastomers with their typical properties. Rating: 1 = Very Good 2 = Good 3 = Satisfactory 4 = Adequate 5 = Poor 6 = Inadequate Legend: mm = Millimeter in = Inch N = Newton daN = Deca Newton KN = Kilo Newton kg = Kilogram N/mm = Newton/Millimeter lbs/in = Pound/Inch
