  • Our polyurethane tank insulation spray coating uses a high closed-cell formula with a closed-cell rate of over 90% and a thermal conductivity as low as 0.022 W/(m·K). This allows it to quickly form a dense, seamless insulation layer on the tank surface, significantly reducing heat loss.
  • The material has a controllable expansion ratio and strong adhesion (≥ 0.3 MPa), maintaining uniform foaming on vertical, horizontal, and large curved tank surfaces without sagging or collapsing.
  • The material has a temperature resistance range of -40℃ to 120℃, is resistant to aging, waterproof, and corrosion-resistant, and maintains stable insulation performance even after long-term use.
  • We also offer customized formulas to better suit customer temperature requirements, construction environments, and tank types, resulting in more efficient and durable insulation.
