Product Description

Product Description

Our nitrile rubber elastomeric foam insulation board is manufactured from premium closed-cell NBR foam material, tailored for thermal insulation in HVAC ducts, refrigeration equipment, pipelines and building projects. Fully compliant with ASTM C534 and ASTM E84 standards, it boasts excellent thermal insulation, fire resistance, moisture-proof and anti-condensation performance. With a wide service temperature range, rich specifications and multiple surface options, it effectively cuts energy loss and serves as a reliable, cost-effective solution for diverse thermal management demands.

This rubber plastic foam insulation board delivers exceptional thermal efficiency and reliable fire safety strictly meeting ASTM standards. Its thermal conductivity is ≤0.034 W/m·K at 23℃, which significantly minimizes heat transfer and reduces long-term energy consumption. Rated ASTM E84 Class A, it features self-extinguishing properties with ultra-low flame spread and smoke emission. The ≥95% closed-cell structure brings ≤0.5% water absorption, delivering excellent moisture resistance to prevent condensation, mold growth and material degradation in high-humidity environments.

We provide flexible product solutions and full-range support to match varied project requirements. The board is available in thicknesses from 10mm to 30mm and widths of 1m/1.2m/1.5m, with plain, self-adhesive and aluminum foil faced surface types, and custom length is also supported. With rigorous quality control throughout production, we ensure stable and consistent product performance. We also offer OEM & ODM services, competitive pricing, fast delivery, along with professional technical consultation and comprehensive after-sales service.

Product Applications

Our elastomeric foam insulation board is widely applied across industrial, commercial and construction scenarios. It is an ideal choice for HVAC air ducts and central air conditioning systems, reducing cold and heat loss during air transmission, improving system operating efficiency and preventing condensation on duct surfaces. For refrigeration equipment, cold storage facilities and low-temperature pipelines, it maintains stable low-temperature environments, avoids frost formation and lowers refrigeration energy costs. It also fits industrial cold & hot water pipes and chemical pipelines, protecting pipes from temperature fluctuation and corrosion. In building construction, it is used for roof, wall and floor insulation, enhancing building thermal performance while providing sound absorption. Additionally, it serves in mechanical equipment rooms for noise reduction and anti-condensation projects, extending the service life of equipment and pipelines.
