Compressed materials

Compressed materials are manufactured in a process that combines water, latex, fibers, fillers, and chemicals to form a slurry, which is calendered using a large heated roller and a smaller cold roller. The slurry is layered on the hot roller until it reaches the desired thickness. Compressed materials tend to have a high density and tensile strength, with a tighter compressibility range than Beater-Addition materials. Compressed materials may also be reinforced with wire mesh or expanded metal for additional strength.

Beater-Addition materials

Beater-Addition materials are manufactured in a process that combines water, latex, fibers, fillers, and chemicals to form a slurry which is processed through a system of rollers to form a solid continuous roll of material in various gages. Higher temperature materials typically utilize aramid fibers, while lower temperature grades are usually made of cellulose fiber. Some grades also have a dispersion of fine cork granules.
