PU Spray Applications
From building insulation to chemical-resistant tank linings, polyurethane and polyurea spray systems power some of the most demanding industrial applications. Below: five primary use cases, the JYYJ machine series we recommend for each, and project case studies from real customers.
By Industry
Each industry vertical has its own pressure, hose-length, and chemistry requirements. Our machine lineup spans all three.
Construction & Insulation
Building envelope, roofing, attic, wall, cold storage. Continuous closed-cell PU foam delivers R-6.5 to R-7 per inch with full air-sealing in a single application.
Industrial Coatings
Tank linings, secondary containment, chemical-resistant flooring, marine and offshore. Polyurea and high-density PU systems handle aggressive chemistries and thermal cycling.
Cold Chain & Refrigeration
Cold storage panels, freezer rooms, vaccine logistics. -40°C service temperature with closed-cell stability and food-contact compliance paths.
