Safety is paramount in any construction project, and the fire resistance of building materials is a critical consideration
. Mineral fiber ceiling boards generally exhibit excellent fire-rated properties, with many products classified as Class A materials according to ASTM E84 testing standards. This classification indicates that the boards have a low flame spread index, which is crucial for reducing the risk of fire in commercial and residential spaces....

- The superiority of NBR as a sealing material stems from its molecular structure, which combines the durability of butadiene with the chemical resistance of acrylonitrile. This blend creates a resilient elastomer that can operate effectively in applications spanning from automotive engines to hydraulic systems in heavy machinery. Its elastic properties ensure a tight fit, preventing leaks and prolonging the lifespan of machinery by minimizing maintenance requirements.
