ABSTRACT:
A brush with a one-piece plastic brush body produced by injection moulding comprises a head covered with bristles and a dimensionally stable handle with a larger cross-section than the head, the brush body being made from an elastomer mixed with a foaming agent and the plastic is foamed in an area of the handle and is solid in the area of the head. The brush is produced by injection moulding in a two-part mould. An elastomer and a foaming agent are mixed during moulding. The mould cross-section for forming the head is smaller than the mould cross section for forming the handle with the elastomer being only foamed in the area of the handle.
