Polymer structures (1) having a laminated surface and enhanced physical properties that can be used for packaging, athletic gear (e.g. padding, water sport equipment), gaskets, and protective garments are decribed. The structures (1) include a core (4) of relatively high density material and one or more layers (6) laminated to the surfaces of the core material of relatively low density polymer foam. The structures (1) can be stiff or flexible. The foam layers improve the softness of the surfaces of the core material.
L'invention concerne des structures de polymères (1), possédant une surface stratifiée et dotées de propriétés physiques améliorées, pouvant être utilisées pour des emballages, des équipements de sport (par ex. rembourrage, équipement de sports nautiques), des joints d'étanchéité et des vêtements de protection. Ces structures (1) comprennent un matériau d'âme (4) à densité relativement élevée, et une ou plusieurs couches (6) stratifiées contre les surfaces du matériau d'âme, lesdits couches étant constituées d'une mousse de polymère à densité relativement basse. Ces structures (1) peuvent être rigides ou flexibles. Les couches de mousse améliorent la souplesse des surfaces du matériau d'âme.
