FIELD: chemistry.

SUBSTANCE: protective element comprises a polymeric material formed by drawing from the thermoplastic composition. The thermoplastic composition comprises a continuous phase comprising a matrix polymer, and in which the microinclusion additive and the nano-inclusion additive are dispersed in the form of discrete domains, and further comprises a phase interface modifier. The material defines a pore network that includes a plurality of nanopores with an average cross-sectional dimension of about 800 nanometres or less. The matrix polymer comprises a polyolefin or a polyester. The microinclusion additive includes a polyolefin (a propylene homopolymer, a propylene/α=olefin copolymer, an ethylene/α-olefin copolymer or a combination thereof, a nano-additive is polymeric (functionalized polyolefin, polyepoxide).

EFFECT: increased necessary protective properties.
