It is a two-component rigid polyurethane (PUR system) that is blown by blowing agent 141B. Characteristics and use Typical use: Specially designed for the production of insulated water heaters and ice boxes. Properties of the resulting foam: The resulting foam has good adhesion to the substrate (surface). It has good insulation properties (thermal insulation).
- Uses
- Manufacture of PU/PIR sandwich panels for building and industrial insulation applications.
- Production of insulated wall, roof, and cold storage panels by discontinuous method.
- Suitable for refrigeration units, prefabricated cabins, portable buildings, and HVAC duct panels.
- Can be used in applications requiring high thermal resistance and dimensional stability at elevated temperatures.
Design Features
- Two-component system (polyol and isocyanate) based on 141B blowing agent.
- Forms polyisocyanurate (PIR) foam with superior fire performance (B2 as per DIN 4102) compared to conventional polyurethane foams.
- Excellent adhesion to a variety of facings such as steel, aluminum, and kraft paper laminates.
- Produces foam with high compressive strength and improved thermal insulation efficiency.
- Good dimensional stability under thermal cycling and humidity exposure.
- Optimized cream and gel times suitable for discontinuous panel production lines.
- Low friability and closed-cell structure ensuring minimal water absorption.
- Can be formulated to achieve density ranges from 35–45 kg/m³ as per process requirements.
