Abstract
Abstract A silicone rubber composition mainly comprising an organopolysiloxane of the average compositional formula: R 1 n SiO (4-n)/2 wherein R¹ is a substituted or unsubstituted monovalent hydrocarbon group and n = 1.98 to 2.02 can be rendered antibacterial and antifungal by blending a zeolite containing 0.1 to 15% by weight of a silver ion.
