This invention relates to a composition comprising a mixture of: (A) an elastomeric material having a modulus at 100% elongation of 0.1-10 MPa; and (B) a non-reactive silicone fluid having a viscosity of 1,000-3,000,000 mPas at 25°C. The elastomer is preferably a silicone elastomer. The invention also provides an impact-resistant material comprising the composition and a shaped article, e.g. a moulded article, made therefrom. The composition provides impact resistance.
