Rubber foam is a flexible, closed-cell insulation material known for its softness, bendability, and resistance to extreme temperatures, flame, and moisture. With low thermal conductivity, it effectively reduces heat loss in pipes and containers across industries such as HVAC, construction, chemical, textile, metallurgy, automotive, and electrical. It is easy to install, offers a clean appearance, and is dust-free, mold-resistant, and durable, making it a versatile insulation solution.
