A dairy inflation (10) for use in a milking device, including a flexible sleeve (24) adapted to surround a teat, wherein the flexible sleeve (24) includes a clear polyurethane composition. The clear polyurethane composition can be derived from a polyol mixture including a glycerine-based polyol having an average molecular weight in a range from about 200 g/mol to about 300 g/mol, and a first hydroxyl value; and a glycol-based polyol having an average molecular weight in a range from about 600 g/mol to about 700 g/mol, and a second hydroxyl value; and about 0.65 to about 1.05 stoichiometric equivalents of a cross-linking agent comprising a plurality of isocyanate groups, wherein the stoichiometric equivalents is based on a sum of the first and second hydroxyl values.
