Abstract
A diaphragm (20) for a diaphragm valve is described. The diaphragm (20) has a body (22) comprising a first elastomer and a resistant layer (24) comprising a second elastomer having a different composition or formulation. Diaphragms described in examples have good flexibility with a high level of chemical resistance and low surface adhesion. A fixing attachment for fixing the diaphragm in the valve is also described.
