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