METAL PROCESSING INDUSTRY
Woolen penumbra is a type of textile material made of wool fibers that have been processed and pressed. This non-woven material is primarily famous for its softness, warmth and insulating properties.
Wool felt can be made in different thicknesses and densities, which allows it to serve different purposes. In the metal processing industry, material is preferable, since it has a high burning threshold of 320 degrees Celsius.
