PROBLEM TO BE SOLVED: To provide a composition for a rubber mat, usable as a dustproof mat or a dustproof sheet mat resistant to the dissolution of components even by washing with a strongly alkaline detergent and free from the generation of wavy deformation, breakage caused by insufficient strength, shrinkage, etc. SOLUTION: The composition for a rubber mat at least contains a synthetic rubber and a plasticizer. The plasticizer has a solution viscosity of 0.6-1.2 Pas and is composed of an adipate-based polyester having molecular terminals modified with isononyloxy group. The content of the plasticizer is 20-40 pts. based on 100 pts. of the synthetic rubber and the composition has a Mooney viscosity of 25-45. COPYRIGHT: (C)2004,JPO
