Enhancing Building Safety & Efficiency with B2 Fire-Retardant PUF Boards

In the realm of modern construction, the demand for high-performance insulation materials that prioritize both thermal efficiency and fire safety is paramount. Among the leading solutions available, the Langfang B2 Fire-Retardant Polyurethane Foam Board stands out as a premium choice for architects, contractors, and builders. Manufactured by Xinzhixingyuan in Langfang, this board is engineered to deliver exceptional performance in demanding applications, particularly within XPS外墙保温系统 (XPS External Wall Insulation Systems).

This board, with货号 YC2023040603, is specifically categorized as a防火板 (fireproof board) and保温板 (insulation board). Its core competency lies in its unique material composition and certified properties. The material is rigid polyurethane foam in a微孔状 (microcellular) structure, crafted into a standard长方形 (rectangular) shape measuring 1200*600*70mm. This specific规格 (specification) offers excellent coverage and ease of installation for large surface areas like roofs and external walls.

Key Technical Specifications and Performance Advantages

The technical data of this polyurethane board reveals why it's a superior insulation product. A critically low导热系数（常温） (thermal conductivity coefficient at room temperature) of 0.035 W/(m·K) signifies outstanding thermal resistance, ensuring minimal heat transfer and leading to significant energy savings for heating and cooling. Its mechanical strength is robust, with both抗压强度 (compressive strength) and抗弯强度 (flexural strength) rated at 177 kPa, providing durable structural support and resistance to deformation under load.

Beyond insulation, the defining feature is its fire safety credentials. Classified with a防火等级 (fire rating) of B级 (B2 grade), this board is阻燃型 (flame-retardant). The 离火自熄 characteristic means it is self-extinguishing; upon removal of an ignition source, the flames will cease, dramatically improving a building's passive fire protection. Additional material properties include a断裂伸长率 (elongation at break) of 8% and a低温弯折 (low-temperature bending) rating of ≤ -9%, indicating good flexibility and cold-temperature durability.

Application and Customization Potential

The primary应用范围 (application scope) for this board is within XPS外墙保温系统, making it an ideal component for comprehensive exterior wall and屋顶保温板 (roof insulation panel) projects. Its ability to withstand a使用温度 (service temperature) of up to 200°C further broadens its suitability for various climatic and operational conditions. For businesses looking to develop their branded line, the manufacturer offers OEM services, allowing for custom branding and packaging.

It is important to note commercial details: this product is supplied by a一般纳税人 (general taxpayer) entity and is currently not designated as a是否跨境出口专供货源 (cross-border export-specific supply). The listed price is税运说明 (tax and shipping说明):不含税运 (excluding tax and freight). These costs are calculated separately based on the具体的货量 (specific order quantity), ensuring transparent and scalable pricing for bulk procurement.

Conclusion: A Smart Investment for Modern Construction

The Langfang Polyurethane Foam Board from Xinzhixingyuan represents a fusion of safety, efficiency, and reliability. Its B2 fire-retardant certification, combined with excellent thermal insulation and structural properties, makes it a compelling choice for any project where building performance and occupant safety are non-negotiable. By choosing this product, you are not just selecting an insulation material; you are investing in a safer, more energy-efficient, and compliant building envelope.
