Expanded rubber articles (11) and processes for making such, comprising: partially curing an expandable rubber formulation (2) by heating it in a first mould cavity (1) to form a moulded blank (3); releasing the moulded blank (3) from the first mould cavity (1) and allowing the moulded blank (5) to expand to form an expanded moulded blank (4); and further curing and expanding the expanded moulded blank (4) by heating it to form the expanded rubber article (11) comprising an expanded rubber part (6), wherein the expanded moulded blank (4) is heated in a second mould cavity (5). Optionally, the expanded moulded blank (4) is contacted with a further rubber formulation (7) and a substrate comprising a base material (9) and an elastomer bonding layer (8) in the second mould cavity (5) to form an expanded rubber article additionally comprising a solid rubber part (10) and a substrate (8, 9).
