• The VI AB®CDM polyurethane rubber series sound insulation pads are a sustainable type of vibration isolation pad. They can be used in both wet and dry acoustic floating floor constructions. Made from polyurethane and bonded to high-density non-woven fabric with a polyurethane elastomer, these pads come in different densities suitable for varying loads, resulting in different hardness characteristics. CDM is particularly known for its notable stiffness ratio, such as a low dynamic/static stiffness ratio, which makes it an ideal material for vibration and sound insulation. It can effectively absorb vibrations and noise across all frequencies, improving impact sound insulation by 16–35 dB, allowing building floor impact sound insulation to surpass current green building standards and meet or exceed the standards of five-star hotels.

• The VI AB®CDM polyurethane rubber series soundproof mats, due to their thin material thickness and excellent flexibility and adhesion, can closely fit the surface of concrete floors. Tiles or stone can be directly adhered on top using 35mm dry-mix mortar or 10mm special adhesive, with almost no impact on indoor ceiling height or construction process.
  
• The VI AB®CDM polyurethane rubber series sound insulation pads have a high coefficient of friction on the surface, making them difficult to shift after installation, which helps with wind resistance and finished product protection. With a thin thickness and high stiffness, they can significantly improve the foot-feel of various common low-density foam soundproof pad products, completely eliminating quality risks such as hollowing and cracking. At the same time, since the material's upper surface is laminated with a layer of tough geotextile, it helps reduce the product's lateral shrinkage. When combined with the surface mortar, it does not produce hollowing or cracking caused by product shrinkage, as seen with traditional foam sound insulation pads. It effectively prevents damage from foot traffic and wheel compaction, and its mesh-like surface can also enhance bonding with the mortar layer.
  

• The VI AB®CDM polyurethane rubber series soundproof pads offer breakthrough sound insulation performance and excellent construction properties, completely eliminating developers' and designers' concerns about potential quality issues in floor sound insulation systems, promoting the widespread application of floated floor sound insulation, and thereby improving the indoor acoustic environment quality of residential buildings in China.
