Product Description

Product Description

Polyurethane Spray Blend Polyols 

VS-3  is spray blend polyols, blowing agent is 245fa instead of HCFC-141B, it reacts with isocyanate to produce foam which has excellent performances, which are as follows,
  1) Fine and uniformity cells
  2) Low thermal conductivity
  3) Perfect flame resistance
  4) Good low temperature dimensional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines etc.

Products Application

1. Insulation
   Building Insulation
   Widely used in the insulation of building walls, roofs, and floors. When sprayed, they react with isocyanates to form a rigid polyurethane foam  with low thermal
    conductivity, which can effectively reduce heat transfer and energy consumption for heating and cooling.
2. Sound - Proofing
    Automotive Industry: In cars, PU spray - blend polyols are applied to the interior parts such as the floor, firewall, and door panels. The sprayed foam can absorb and  
    dampen sound waves, reducing engine noise, road noise, and external noise, thus creating a quieter and more comfortable driving environment.
    Building Interior: In buildings, especially in areas where sound - proofing is required, such as recording studios, theaters, and conference rooms, PU spray - blend
    polyols can be used on walls and ceilings. The foam helps to block sound transmission between different spaces and reduce reverberation within the room.
3. Structural reinforcement
    Composite Materials: PU spray - blend polyols can be used in the production of composite materials. When sprayed onto fiberglass or other reinforcing materials, they 
    form a strong and lightweight composite structure. This is widely used in the aerospace, marine, and wind - energy industries.
    Building repair and reinforcement: In building construction and repair, PU spray - blend polyols can be used to reinforce damaged or weak structures. For example,
    spraying the polyols on cracked concrete walls or columns can fill the cracks and form a strong bonding layer, enhancing the structural integrity of the building.
4. Decorative applications
    Art and Sculpture: PU spray - blend polyols can be used in the creation of artworks and sculptures. The sprayed foam can be shaped and carved easily, and then
    painted or treated with other surface - finishing techniques to create unique decorative pieces.
    Interior decoration: In interior decoration, PU spray - blend polyols can be used to create decorative moldings, cornices, and wall panels. The sprayed foam can be  
    formed into various shapes and patterns, providing an alternative to traditional plaster or wood - based decorative elements.
