Next, we discuss the 40% figure, which can denote the allowable leakage rate for particular types of oil seals. Leakage can severely impact the overall performance of mechanical systems, leading to reduced lubrication and increased wear on components. A reputable oil seal must minimize leakage to a level that is often benchmarked at around 40% of the maximum allowable threshold for that system. Manufacturers pour significant resources into developing materials and designs that can achieve this standard, as minimizing leakage not only conserves lubricant but also enhances the efficiency and longevity of the machinery.

Fire resistance is another critical attribute of mineral and fiber boards. With increasing regulations regarding fire safety in construction, materials that can withstand high temperatures and limit fire spread are in high demand. The mineral content, particularly gypsum, endows these boards with excellent fire-resistant qualities, ensuring improved safety in buildings while offering peace of mind to both manufacturers and consumers.
