Enhancing Building Safety & Efficiency with Langfang B2 Fire-Retardant Polyurethane Foam Boards

In the world of construction and insulation, finding materials that offer both exceptional thermal performance and vital fire safety is paramount. This is where specialized products like the Langfang B2 Fire-Retardant Polyurethane Foam Board, manufactured by Xinzhixingyuan, truly excel. Designed for high-performance applications, this board sets a new standard for roofing and exterior wall insulation systems.

Unmatched Thermal Performance for Maximum Energy Savings

The core strength of this insulation board lies in its outstanding thermal properties. With an impressively low thermal conductivity coefficient of just 0.035 W/(m·K) at room temperature, it acts as a powerful barrier against heat transfer. This means buildings stay cooler in summer and warmer in winter, leading to significant reductions in energy consumption for heating and cooling. The board's microporous structure is key to this efficiency, trapping air within its polyurethane core to minimize thermal bridging.

Superior Fire Safety: The B2 Fire-Retardant Advantage

Safety is non-negotiable, and this product is engineered with that principle at its core. Classified as a B2 grade fire-retardant material, it features a self-extinguishing property. This means the board will cease to burn once the external flame source is removed, a critical feature for slowing the spread of fire and enhancing overall building safety. It is specifically indicated as a fireproof custom solution, making it an ideal choice for projects with stringent safety regulations.

Robust Physical & Mechanical Properties

Durability meets performance in this high-specification board. It boasts a compressive strength of 177 kPa and a matching flexural strength of 177 kPa, ensuring it can handle structural loads and resist deformation. With a low-temperature flexure of ≤9% and an elongation at break of 8%, the material maintains its integrity and flexibility even under stress or in varying temperature conditions, up to a service temperature of 200°C.

Specifications & Ideal Applications

This rectangular-shaped board comes in a standard specification of 1200*600*70mm, making it easy to handle and install. Its primary application scope is within XPS exterior wall insulation systems, where it performs excellently as both a roof insulation board and a general thermal insulation panel. Sourced directly from Langfang (Item#: YC2023040603), it represents a reliable domestic supply chain option for contractors and builders.
