Superior Roof Insulation: Discover the B2 Fire-Retardant Polyurethane Foam Board

In the demanding world of construction and insulation, finding a material that balances exceptional thermal performance with critical fire safety is paramount. Enter the Langfang B2 Fire-Retardant Polyurethane Foam Board from Xin Zhi Xing Yuan. This premium insulation board is engineered to meet rigorous standards, offering an ideal solution for modern XPS外墙保温系统 (XPS exterior wall insulation systems) and beyond.

At its core, this board utilizes high-quality polyurethane as its芯材 (core material), processed into a微孔状 (microcellular) structure. This advanced morphology is key to its impressive thermal conductivity coefficient of just 0.035 W/(m·K) at常温 (room temperature). Such low conductivity translates directly into superior energy efficiency, significantly reducing heat loss in buildings and leading to substantial cost savings on heating and cooling.

Engineered for Safety and Strength

Safety is non-negotiable. Classified as a B级 (Grade B)防火板 (fireproof board), this product is specifically designed as a阻燃型 (flame-retardant type) material. Its 离火自熄 (self-extinguishing) property means the board will cease burning once the flame source is removed, a critical feature for enhancing building safety and compliance.

Beyond fire resistance, the board boasts remarkable mechanical integrity. With both抗弯强度 (flexural strength) and抗压强度 (compressive strength) rated at 177 kPa, it can withstand significant structural loads. Coupled with a断裂伸长率 (elongation at break) of 8% and a低温弯折≤ (low-temperature bending) rating of 9%, this insulation board demonstrates excellent durability and flexibility under various environmental stresses, ensuring long-term performance.

Specifications and Reliable Supply

Supplied in a convenient长方形 (rectangular) shape measuring 1200*600*70mm, this保温板 (insulation board) is ready for efficient installation. It operates effectively within a使用温度 (service temperature) range of up to 200°C. As a product proudly manufactured in廊坊 (Langfang) with货号 (item number) YC2023040603, it represents reliable industrial sourcing.

The manufacturer,鑫智兴源 (Xin Zhi Xing Yuan), supports OEM services and provides防火定做 (custom fireproofing solutions). They operate as a一般纳税人 (general taxpayer), ensuring professional business transactions. Note that税运 (tax and shipping) are not included in the base price and are calculated based on order volume. This product is currently designated as非跨境出口专供货源 (not a cross-border export exclusive supply).

Ideal Applications

This versatile polyurethane foam board is primarily designed for XPS外墙保温系统 (XPS external wall insulation systems), making it a top-tier choice for architects and builders focusing on external cladding and roofing projects. Its combination of insulation, fire retardancy, and strength also makes it suitable for various other commercial and industrial insulation applications where safety and efficiency are priorities.

Conclusion

The Langfang B2 Fire-Retardant Polyurethane Foam Board is more than just insulation; it's a comprehensive building solution. By integrating top-grade thermal resistance (0.035 thermal conductivity) with proven fire-retardant (B2 grade, self-extinguishing) properties and robust physical strength (177 kPa), it delivers unmatched value for professional construction projects. Choose this board for reliable performance, enhanced safety, and energy-efficient outcomes.
