摘要： The invention relates to a process for the production of a non-fibrous drawn polymer tape, said process comprising the steps: a) compacting a polymer powder in a press to form a compacted polymer bed; b) calendering said compacted polymer bed to form an oriented polymer tape; and c) drawing said oriented polymer tape to form a highly oriented polymer tape; characterized in that step a) comprises compacting the polymer powder at a temperature and pressure such that from 0.1 to 20 wt. % of the polymer powder as measured by DSC is melted. The invention also relates to a tape obtainable by the above process, and a monolayer, multilayered material sheet and ballistic resistant article comprising such a tape.

摘要： Composite panel comprising at least one layer containing at least one tape comprising a thermoplastic polymer selected from the group consisting of polyolefins, polyesters, polyvinyl alcohols, polyacrylonitriles, polyamides or polyketone, wherein the tape has a tensile strength of at least 1.2 GPa and an areal density of between 5 and 150 g/m2, and an adhesive in contact with said layer, whereby the amount of the adhesive in contact with one side of the at least one layer is between 0.2 and 15 g/m2, wherein the adhesive is a plastomer wherein said plastomer is a random copolymer of ethylene or propylene and one or more C2 to C12 a-olefin co-monomers and wherein said plastomer has a density as measured according to 1801183 of between 860 and 930 kg/m3. In a preferred embodiment the tape comprises an ultra high molecular weight polyethylene. The composite panel is used in a ballistic resistant article.
