Vila Rock Wool Pheno Felt: High-Strength, Flexible Insulation for Complex Industrial Surfaces

The optimal solution for insulating curved surfaces, tanks, and irregular equipment – heat resistant up to 750°C

Product Technical Introduction:

Vila Rock Wool Pheno Felt is manufactured from basalt stone fibers bonded with a specialized, heat-resistant phenolic resin. The presence of this binder significantly enhances the product’s mechanical strength, structural integrity, and resistance to vibration. Its uniform yet flexible composition allows for easy and seamless installation on surfaces with complex geometries, ensuring a tight fit and eliminating thermal gaps.

Key Advantages of Vila Rock Wool Pheno Felt:

High Flexibility: Easily wraps around curved and irregular surfaces without cracking or breaking.

Excellent Mechanical Strength: Resistant to vibration, compression, and mechanical stress.

Efficient Thermal Insulation: Low thermal conductivity coefficient minimizes energy loss.

Fire Resistance: Non-combustible (Class A1) and can withstand continuous temperatures up to 750°C.

Quick and Easy Installation: Can be cut and shaped with simple tools, reducing installation time.

Chemical Resistance: Resists degradation from industrial vapors and most chemicals.

Long Service Life: Maintains its structural and thermal properties in harsh operating conditions.

Main Applications:

Steel and Smelting: Insulation of induction furnaces, ladles, and molten metal transfer channels.

Refineries & Petrochemicals: Insulating spherical tanks, reactors, and distillation columns.

Power Plants: Wrapping turbines, boilers, and high-pressure steam systems.

Cement Industry: Insulating rotary kilns and preheaters.

Industrial HVAC: Insulating large-diameter ductwork with complex shapes.

Marine & Shipbuilding: Insulating ship hulls, bulkheads, and floating vessels.
