PUR is a two-component polyurethane (PUR) system, blown by blowing factor 141B, and is used to produce polyurethane systems with a density of 32 to 35 kg/m³ intended for the insulation of water coolers. Key Properties of Foam When BC 704 Polyol reacts with BC 768 Isocyanate, it forms a rigid highly interlocking polyurethane foam characterized by: dimensionally stable. Good adhesion to metal plates.
- Uses
- Production of rigid polyurethane foam for water cooler insulation.
- Suitable for domestic and commercial water dispensers.
- Ideally designed for insulating cooling tanks, reservoirs, and body shells of water coolers.
- Can be used for thermal insulation applications requiring medium-density rigid foam.
Key Properties / Design Features
- Two-component polyurethane system (BC 704 Polyol & BC 768 Isocyanate).
- Blown with 141B for controlled foam expansion and uniform cell structure.
- Produces rigid interlocking foam with high closed-cell content for superior insulation.
- Density: 32–35 kg/m³, optimized for water cooler insulation.
- Excellent thermal insulating performance, reducing heat gain and improving cooling efficiency.
- Dimensionally stable foam under varying temperature and humidity conditions.
- Strong adhesion to metal surfaces, ensuring structural reinforcement and long-term durability.
- Low water absorption for better insulation life and moisture resistance.
- Smooth and uniform finish suitable for mass-production molding systems.
