Product Description Polyurethane Spray Blend Polyols - VS-3Product DescriptionVS-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.Product ParametersPhysical PropertiesAppearance Hydroxyl Value mgKOH/gDynamic Viscosity (25 oC) mpa.sSpecific gravity (20 oC ) g/mlStorage Temperature oCStorage Stability monthPale yellow to brown viscous liquid200-300100-2001.12-1.2010-256Recommended Ratio pbwVspray-3 blend polyolsIsocyanate100100-105Reactivity Characteristics(The temperature of the system is 20oC,and the exact value varied depending on processing condition)Cream Time sGel Time s3-56-10Foam PerformancesItemsTest MethodIndexSpray Density Closed-cell Rate Initial Thermal Conductivity(15oC) Compressive StrengthAdhesive Strength Elongation at breakDimentional Stability 24h -20oC 24h 70oC Water Absorption Oxygen IndexGB 6343GB 10799GB 3399GB/T8813GB/T16777GB/T9641GB/T8811GB 8810GB 8624 30-40kg/m3 ≥90% ≤24mW/(m.K) ≥150kPa ≥120kPa ≥10% ≤1% ≤1.5% ≤3% ≥26Products Application1. 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.Our Advantages Packaging & ShippingCompany Profile
