Wholesale Kingflex foam rubber pipe insulation Supplier, Factory

What is Elastomeric Foam Insulation? Essentially, elastomeric foam insulation is a synthetic rubber composed of a closed-cell structure available in factory-made tubes, sheets, or rolls. The outside edge consists of a smooth surface or “skin” which serves as a built-in vapor retarder. Due to elastomeric foam’s flexible nature, it is less susceptible to cracks, breakage, and material loss when compared to rigid insulation options such as cellular glass, polyiso and phenolic foam. Finally, it’s also fiber-free and low-VOC for chemical emissions.阿
