VietnamCF - RUBA
Product Description
Product information
CF-FLEX High Density Acoustic Foamed Rubber is engineered and desighed specifically for sound absorption, and vibration dampening. The complex open cell structure is an excellent barrier of sound frequency ( transmission) and effectively controls noises at a broad range of frequencies. The high density foam structure and asymmetrical pore structure means that it absorbs 50% more sound when compared regular nitrile open cell foams.
CF-FLEX High Density Acoustic Foamed Rubber can replace traditional sound absorbing materials whilst using lower thickness. Available in various sizes, users can customize their applications to suit their own needs.
Environment
CF INSULATION High Density Acoustic Foamed Rubber delivers optimal perfoamance without the use of fibers and wools that can be harmful to your health. The foam also does not contribute to mold or fungal growth in high moisture environments which could lead health and safety issues.
Applications
1. HVAC industries such as duct liners, fan coil units, air handing units and chiller systerms.
2. General industries uses such as pipes, machines, plant rooms, etc.
3. Other uses such as automotive applications and sound proof rooms,etc.
Advantages
1. Easy to install and fabricate.
2. No hassles of fibers and fungal growth.
3. Effective noise control and thermal insulation.
4. Good resistance to abrasions and mineral oils.
5. Wide variety of thickness to suit all applications.
