Enhance Building Safety & Efficiency with B2 Fire-Retardant PU Foam Boards

In the realm of modern construction, selecting the right insulation material is critical for energy efficiency, structural integrity, and, most importantly, safety. The B2 Fire-Retardant Polyurethane Foam Board from Langfang stands out as a premier solution for commercial and industrial roofing applications. Manufactured by Xinzhixingyuan, this board combines exceptional thermal performance with reliable fire-resistant properties, making it an ideal choice for demanding projects.

Unmatched Technical Specifications for Robust Performance

This polyurethane insulation board is engineered to deliver consistent and high-level performance. With a remarkably low thermal conductivity coefficient of 0.035 W/(m·K) at room temperature, it provides superior insulation, significantly reducing heat transfer and energy costs. Its mechanical strength is equally impressive, featuring both compressive and flexural strength of 177 kPa, ensuring durability under load. The material exhibits a low-temperature flexure of ≤9% and a断裂伸长率 (elongation at break) of 8%, indicating good flexibility and resistance to cracking in varying climates.

Superior Fire Safety: B2 Grade and Self-Extinguishing

The core feature of this product is its enhanced fire safety. Classified as a B2-grade fire-retardant material, it is designed to resist ignition and slow flame spread. A key safety characteristic is its 离火自熄 or self-extinguishing property; when the flame source is removed, the material will cease to burn. This trait is crucial for roof insulation, providing valuable time in case of a fire and enhancing overall building safety compliance. The microporous structure of the polyurethane芯材 (core material) contributes to this effective fire resistance.

Versatile Application and Customization Options

Primarily designed for XPS外墙保温系统 (XPS exterior wall insulation systems), this rectangular board (1200*600*70mm) is perfectly suited for roof insulation projects. Its application ensures a continuous thermal barrier, preventing thermal bridging. The product is offered with OEM services, allowing for customization in尺寸 (dimensions) and specifications to meet specific architectural plans. With a service temperature of up to 200°C, it remains stable under a wide range of environmental conditions.

Quality Assurance from Langfang Manufacturer

Produced in Langfang by Xinzhixingyuan, a一般纳税人 (general taxpayer) company, this foam board is a testament to reliable manufacturing standards. While the listed price excludes taxes and logistics (which are calculated based on order volume), it represents a cost-effective investment in long-term building performance and safety. The product is identified by货号 (item number) YC2023040603, ensuring traceability and consistent quality.

Conclusion: The Smart Choice for Insulation

For architects, contractors, and builders seeking a high-performance, fire-safe insulation board, the B2 Fire-Retardant Polyurethane Foam Board is a compelling option. It successfully bridges the gap between excellent thermal insulation (功能:保温) and critical fire safety requirements (防火定做). By choosing this product, you are not just insulating a building; you are investing in enhanced safety, reduced energy consumption, and durable construction quality.
