Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

In addition to sound absorption, mineral fiber ceiling boards also offer excellent thermal insulation properties. This quality can contribute to energy efficiency in buildings by helping to regulate indoor temperatures and reduce heating and cooling costs. The R-value is a measurement of thermal resistance, and higher values correspond to better insulating properties. When choosing a mineral fiber ceiling board, it is advisable to look for products with a high R-value to maximize energy efficiency.
