Introduction
Our Water-Based Flexible PU Foam stands out as an eco-friendly innovation, utilizing water as the blowing agent. This sustainable solution boasts remarkable features such as low density (10-12 kg/m³), open-cell structure, and flame retardancy (B3 grade), making it an ideal choice for environmentally conscious applications.
During the on-site spray application, the foam breathes through its small open cells filled with air, ensuring no toxic gases are emitted that could harm the ozone layer. Unlike traditional blowing agents like F-11 and HCFC-141B, our PU foam is a pioneering material for eco-friendly, low-carbon construction solutions.
This advanced spray PU foam offers exceptional qualities including thermal insulation, gas resistance, moisture protection, waterproofing, and
sound absorption, ensuring buildings that are quieter, healthier, and more energy-efficient.
