Abstract

PURPOSE: A rollable sealing material composition, prepared by incorporating a desulfurized regenerated rubber having a specific viscosity with a high polymeric material consisting of a synthetic rubber and a synthetic resin having a specific strength in a specific proportion, and having improved tackiness.
CONSTITUTION: (A) 20W70pts.wt. desulfurized and regenerated powdered rubber having a Mooney viscosity ML1+4 (100°C) of 20W60, e.g. styrene-butadiene copolymer pulverized to a particle diameter of 20W40 mesh, is incorporated with (B) 30W80pts.wt. high polymeric material consisting of one or two or more synthetic rubber and synthetic resin having a green strength ≥50kg/cm2 and if necessary (C) an additive, e.g. a reinforcing filler, and the resultant mixture is then kneaded by a pressurized kneader, and rolled by three rolls, etc. to give the aimed composition having a penetration ≥20.
