Polyurethane Spraying
Wanhua Energy-Saving Spray Rigid Polyurethane Insulation Material features microporous penetrating self-adhesive foaming. Thanks to its closed-cell structure, this insulation material offers low thermal conductivity, dimensional stability, and a wide range of applications.
Polyisocyanurate (PIR) Insulation Sandwich Panel
Wanhua Energy-Saving Polyisocyanurate (PIR) Insulation Sandwich Panels are composed of two layers of color-coated steel plates or other pressed metal sheets as surface materials. They integrate load-bearing, insulation, fireproofing, and waterproofing functions, offering quick and convenient installation along with high energy efficiency.
Spacers
Polyurethane cold storage spacers made from Wanhua's specially formulated high-rigidity polyurethane composite material, these spacers create a thermal break between steel column bases and ground concrete foundations. They are waterproof, anti-condensation, corrosion-resistant, and non-degradable.
Moisture Barrier and Vapor Barrier Materials
Wanhua Energy-Saving cyanate ester is available in single-component and dual-component forms. It reacts with water molecules to form polyurea or cures into a film through self-reaction. The film is highly compatible with polyurethane foam, offering excellent bonding strength, moisture resistance, vapor barrier properties, and chemical resistance.
