ABSTRACT:
The invention relates to a rubber-elastic composition which comprises a polyether material, and which in the completely vulcanized and completely polymerized form, contain 0.1 to 15 wt. %, relative to the total weight of the composition, of at least one hydrophilic nature imparting agent selecting from the group consisting of a hydrophilic silicone oil having one or more siloxane groups as a hydrophobic part and one or more ether groups as a hydrophilic part, a fluorinated hydro-carbon, a block copolymer of ethylene oxide/propylene oxide, a fatty alcohol derivative, an alkyl phenol derivative, a fatty amine, an amine oxide, a fatty acid glycol and glycerin derivative, a fatty acid, and a fatty acid monoester. The composition is suitable as dental impression composition and has, in the completely polymerized state, even with multiple disinfections in an aqueous disinfecting solution, a continuing good ability to flow on (small wetting angle) and an unchanged dimensional stability.
