Enhancing Building Safety and Efficiency with B2 Grade Flame-Retardant Polyurethane Foam Boards

In the demanding world of construction and insulation, finding a material that perfectly balances thermal performance with critical fire safety is paramount. Sourced from Langfang, the Langfang Polyurethane Factory presents its premium B2 Grade Flame-Retardant Polyurethane Foam Board (Product Code: YC2023040603), a solution engineered for excellence in external wall insulation systems and beyond.

Unmatched Core Properties for Superior Performance

Manufactured under the Xin Zhi Xing Yuan (鑫智兴源) brand, this board is crafted from high-quality polyurethane芯材 in a微孔状形态. This structure is key to its exceptional capabilities. The standout feature is its low导热系数 of 0.035 W/m·K at常温, ensuring outstanding thermal insulation that significantly reduces energy loss in buildings.

Commitment to Fire Safety: B2 Grade and Self-Extinguishing

Safety is non-negotiable. This board is rigorously classified as a B2级 (Grade B)防火板 with a specific阻燃型 formulation. Its most critical safety feature is its ability to be离火自熄 (self-extinguish upon removal of fire source). This dramatically reduces flame spread risk, providing crucial time for occupant evacuation and firefighting, making it an ideal choice for enhanced building safety codes.

Robust Mechanical Strength for Durable Applications

Beyond insulation and fire resistance, this长方形 board is built to last. It boasts impressive mechanical properties, including an抗压强度 and抗弯强度 of 177 kPa. With a断裂伸长率 of 8% and a低温弯折≤ rating of 9%, it demonstrates reliable flexibility and durability under stress and varying temperatures, with a使用温度 range up to 200°C.

Specifications and Versatile Application

This versatile保温板 comes in a standard规格 of 1200*600*70mm, a common and workable size for various projects. Its primary应用范围 is withinXPS外墙保温系统 (XPS External Wall Insulation Systems), where it performs as a critical component for cladding, roofs (聚氨酯屋顶保温板), and other insulated assemblies. The manufacturer also providesOEM services and防火定做 (custom fire-proof manufacturing) to meet specific project requirements.

Ideal for Professional Procurement

Targeted at professional and commercial buyers, this product is supplied by a一般纳税人 (general taxpayer) entity. It's important to note that pricing is税运说明:不含税运，税运需按货量进行核算 (exclusive of tax and shipping; these are calculated based on order volume). Currently, it is not designated as a是否跨境出口专供货源 (cross-border export-specific supply).

In summary, the Langfang B2 Grade Flame-Retardant Polyurethane Foam Board represents a smart, safe, and efficient choice for modern construction. It combines low thermal conductivity with vital fire-retardant properties and solid structural strength, all from a reliable manufacturing source. For your next insulation project demanding safety and performance, this product offers a compelling technical solution.
