摘要:
A flexible pipe body layer and method of producing a flexible pipe body layer are disclosed. The method includes coextruding an inner sub-layer and an outer sub-layer, wherein the inner sub-layer and outer sub-layer comprise a polymer, and wherein the inner sub-layer has a lower modulus of elasticity than the outer sub-layer.
