At a time when building safety is crucial, polyurethane sandwich panels of Yanghu Board Industry become reliable fire barriers in the construction field with excellent B1 fire rating, which protects the fire safety of various buildings.

Accurate standards, in line with authoritative norms

According to GB8624 - 2012 "Classification of combustion performance of building materials and products" this strict standard, Yanghu board polyurethane sandwich board by professional institutions, all indicators are accurately in line with the requirements of B1, that is, the grade of flame retardant materials.In the combustion performance test, the flame propagation rate is effectively controlled, the flame spread range within the specified time is small, the fire can be quickly extinguished after the fire, and the fire will not continue to burn, thus reducing the fire risk from the source and laying a solid foundation for building safety.

Performance to meet fire challenges

In the actual application scenario, the B1 fire resistance of the polyurethane sandwich panel of Yanghu Plate Industry is fully demonstrated.In case of fire, the polyurethane sealing layer will quickly carbonize at high temperature to form a dense carbonized layer.This carbonized layer is like a solid armor, which can not only effectively prevent the flame from spreading further inward and deep into the interior of the sandwich panel, but also block the rapid transmission of heat and slow down the damage of the fire to the overall structure of the plate.

Multiple advantages, balance safety and practicality

Compared with ordinary fire rated sheets, the B1 fire rating of Yanghu polyurethane sandwich panels gives them many significant advantages.In the process of building design and construction, B1 fire performance allows designers to have a broader creative space, which can meet the needs of diversified architectural modeling, whether it is complex commercial building appearance or office space pursuing flexible layout, which can be easily adapted without sacrificing design aesthetics due to fire protection restrictions.At the same time, from the long-term use point of view, B1 fire rating means higher safety and reliability, reducing the building maintenance cost and potential economic loss caused by fire hazards, which is the ideal choice for building projects in the pursuit of safety guarantee and economic value balance, and building safety defense lines for the whole life cycle of buildings.
