Polyurethane Block

Polyurethane Block is a rigid thermal insulation material in block form (rigid foam) made from polyurethane (PU) with a closed-cell structure. This material is produced through a chemical reaction process that results in foam with controlled density and excellent insulation performance.

With its very low thermal conductivity, Polyurethane Block is one of the most efficient insulation materials for low to medium temperature applications, especially in systems that require stable temperature control.

Characteristics & Advantages

  • Very Low Thermal Conductivity – Provides highly efficient insulation performance
  • Closed-Cell Structure – Minimizes water and vapor absorption
  • Lightweight & Strong – Offers a good strength-to-weight ratio
  • Good Dimensional Stability – Resistant to deformation
  • Easy to Process & Shape – Can be cut and customized as needed
  • Moisture Resistant – Suitable for high-humidity environments
  • High Energy Efficiency – Significantly reduces energy loss
  • Available in Various Densities – Flexible for different technical requirements
