<p>PURPOSE:To obtain a rubber product excellent in tensile strength, abrasion resistance and the permanent strain in compression and having no burr by a method in which the rubber compound in which 1-7 pts.wt. of coupling agent of silane group, vulcanizing agent and other rubber compounding chemically used generally are added to 100 pts.wt. of rubber, is injected into a mold cavity at a specified temperature, an then is heated and vulcanized. CONSTITUTION:The rubber compound in which 1-7 pts.wt. of coupling agent of silane group, vulcanizing agent and other rubber compounding chemically used generally, are added to 100 pts.wt. of rubber is injected into a mold cavity at 90 deg.C-130 deg.C of injecting temperature, and the cavity is filled therewith. Next, said material is heated at 130 deg.C-190 deg.C and is vulcanized, thereby obtaining the desired rubber product without burrs.</p> |
