Abstract
A gasket material comprised of fibrillated aramid fibers, diatomaceous earth and either a polyethylacrylic or polybutylacrylic latex alone or in combination with conventional curatives, antioxidants and pigments. The constituent materials are combined in a beater-addition process, and the pliable gasket material is then formed on conventional paper making equipment.
