Milking teat liner of particular plastics material with pre-determined hardness, Young's modulus, tensile strength and minimum elongation

摘要

The disclosure is of devices and components for milking apparatus, in particular to milk extracting devices. Especially it relates to components of such devices such as liners (20). The devices comprise a material, selected from the group consisting of thermo-plastic elastomers, as defined in ISO 18064, plasticized PVC, Vinyl TPE, said material exhibiting the following properties: a hardness between 25 shore A and 50 shore D; a Young's modulus between 0.1 MPa and 50 MPa; a tensile strength above 0.5 MPa; and a minimum elongation of 50% without breakage.
