DAMTEC® vibra-hard
Semi-hard decoupling mat made from cellular rubber and recycled rubber granules
DAMTEC® vibra hard is a semi-hard insulation material made from a blend of fine-grained recycled cellular rubber and high-quality recycled rubber. Its upper and lower sides are smooth. DAMTEC® vibra hard is used in applications supporting heavy weights, i.e. compressive stresses ranging from 0.20 N/mm² to 0.30 N/mm².
 |
f₀ ≥ 10,5 Hz Average compressive stress ≤ 0.3 N/mm²
The natural frequency f₀ is dependent on the product thickness and the weight supported.Combined systems (e.g. single, two or even three layers) are possible. |
