Abstract
A barrier layer assembly is useful as a barrier component in articles subjected to repeated deformations. The barrier layer assembly has a support layer and a film layer. The barrier layer assembly has a bi-directionally corrugated surface. The surface may be an external or internal surface and is defined by non-sulcate furrows.
Claims15
A barrier layer assembly, the assembly comprising a support layer and a film layer bonded thereto, wherein the assembly has a bi-directionally corrugated surface, wherein the film layer of the barrier layer assembly comprises a dynamically vulcanized alloy comprising a vulcanized elastomer dispersed in a thermoplastic continuous phase.
A barrier layer assembly, the assembly comprising a support layer and a film layer bonded thereto, wherein the assembly has a bi-directionally corrugated surface, and wherein the support layer is comprised of an elastomeric composition;
- wherein the bi-directionally corrugated surface comprises a three-dimensional structure arranged about a central plane comprising a first curvilinear shape oriented in a first direction along the central plane combined with a second curvilinear shape oriented in a second direction along the central plane non-parallel to the first direction, the curvilinear shape in each direction being the same or different;
- and
- wherein at least a portion of the three-dimensional structure is represented by the equation:
- z=a(sin(bx+sin(cy)))
- wherein z is the distance orthogonal to the central plane between the structure and the central plane;
- x is a relative distance in the first direction along a length of the central plane;
- y is the relative distance in the second direction orthogonal to the first direction and orthogonal to the central plane along the width of the central plane.
