Vibration blocking materials are widely required from OA, precision instruments and home appliances to machinery equipments. The VBRAN Dynaox is offering converts and absorbs noise, vibration and shock into thermal energy. In comparison with the traditional asphalt or rubber and non-vulcanized IIR, VBRAN is suitable for light weight applications due to its lighter specific gravity and also applicable for various purposes because of its wide material availability and excellent processing flexibility with an example of large width (1M) and length (10M) which can contribute to cost reduction.
