Beater-Saturation Materials (below)
The Beater-Saturation process uses a Fourdrinier or cylinder type paper machine to deposit a binder (i.e. SBR, Neoprene, Nitrile) uniformly over individual fibers (i.e. cellulose, synthetic fibers, etc.) while suspended in water. The material is thus passed through a series of calender operations until a uniform quality gasket sheet emerges.
Tensile strength and compressibility are determined by the degree of calendering. Unlike compressed sheets, beater- saturated sheets are relatively short fibers. The two sheets are entirely different both in structure and method of formation.
The paper making method produces a continuous roll form up through 1/16" (1.5mm) thicknesses. Increased thickness is obtained through lamination.
