PURPOSE:To obtain the title composition which is applied to rubber materials, such as tire, before vulcanization for discriminating the rubber materials in the manufacturing process so that misuse of the material can be prevented, by mixing a rubber with a specified white waxy powder. CONSTITUTION:The title composition is obtained by mixing 100 pts.wt. rubber with 200-5,000 pts.wt. white waxy powder having a melting point of 40-160 deg.C and a value K defined by the formula of at least 75, preferably 75 to 95. |
