Silicon and EPDM made sponge rubbers are well known for their excellent acoustic attribute and strong anti vibration level. Rectangular in shape, these rubber profiles are accessible in 20 Shore A to 90 Shore A hardness range. Gaskets made of sponge rubbers possess high shock absorption capacity and strong compression rate. Open cell structure of this range of rubbers is useful to develop electrocardiogram pads, sterilization products etc. Light in weight, this range of rubber has excellent buoyancy level. Strong thermal insulation level and accessibility in different density level are undoubtedly some of the key features of this range of rubber.
