AOFENG One-component Spray Polyurethane Foam Sealant – Multi-scenario High-performance Filling & Sealing Material

Driven by the rising global demand for building energy conservation, door & window sealing and home renovation filling, Aofeng Group has invested deeply in R&D of polyurethane new materials. Our one-component spray polyurethane foam sealant stands out as a mainstream filling & sealing consumable for construction, home decoration and equipment manufacturing industries worldwide, featuring easy operation, high expansion rate, thermal insulation and sound insulation. The product is widely exported to Southeast Asia, South America, the Middle East and other overseas regions.

1. Core Product Performance Advantages

This aerosol-type single-component PU foam requires no on-site mixing. It can be directly sprayed with a matching professional spray gun as shown in the picture, enabling simple one-person operation:

High Expansion Rate & Dense Filling The foam expands rapidly after spraying to fully fill gaps and cavities without hollow spaces, eliminating air leakage and water seepage risks. The cured foam features strong flexibility and resists cracking under minor deformation, compatible with wood, metal, plastic, concrete and most substrates.
Excellent Thermal & Acoustic Insulation for Energy Saving The solidified foam delivers outstanding heat insulation and sound absorption. Filling gaps around doors, windows and walls blocks heat transfer to cut building energy consumption, while reducing external noise transmission to meet energy-saving standards for houses and factories.
Waterproof, Moisture-proof & Weather-resistant Closed-cell structure prevents water absorption and mildew growth. The foam resists extreme temperatures and aging, avoiding pulverization or shrinkage during long-term outdoor use, suitable for tropical South America and cold northern areas.
High-efficiency Spraying Construction Pressurized aerosol cans with extended spray guns support long-distance and large-area filling. Compared with straw-type foam, spraying mode doubles construction speed, saves labor time and reduces overall engineering costs.

2. Wide Application Fields

Construction Door & Window Projects Gap filling between window frames and walls, curtain wall joint sealing, exterior wall hole repair; fixes window structures and integrates sealing & thermal insulation.
Interior Home Renovation Ceiling cavity filling, pipe wall gap blocking, cabinet gap sound insulation to improve indoor thermal and acoustic performance.
Cold Chain & Equipment Manufacturing Insulation filling for cold storage panels, air conditioning pipe sealing, heat insulation for container gaps to reduce equipment energy loss.
Industrial & Infrastructure Maintenance Wood panel joint filling, steel structure gap sealing, roof small hole repair for quick waterproof sealing.
Custom OEM Export Service Custom can printing, foam hardness and flame retardant formulas are available to meet local construction standards. We provide full export certifications including CE and flame retardant test reports.
