Abstract:
The invention relates to adhesive tape having a support made of a film, an adhesive mass being applied to at least one side thereof. Said film is a monoaxially stretched film which is made up of at least 50 wt. % of a polypropylene homopolymer and 10-25 wt. %, preferably 15% of a copolymer made from ethylene and 2-6 mol % of an α-olefin. The α-olefin is a diene having at least four carbon atoms, the adhesive mass contains a polyisoprene rubber and one or more adhesive resins, the rubber/adhesive resin weight ratio being higher than 1.10.
Abstract:
The invention relates to a bio-based film comprising a composition based on poly(lactic acid), said composition containing the following components: (a) at least one bio-based co-polymer based on at least one lactic acid derivative; (b) at least one plasticizer comprising at least one compound which contains at least one ester group, excluding dimeric and polymeric esters of lactic acid; (c) at least one nucleation agent; and (d) optional additives.
Abstract:
Adhesive tape, in particular for wrapping elongated material such as cable harnesses in an automobile, comprising a carrier material that is provided at least on one side with an adhesive coating, characterized in that the carrier material comprises at least one layer containing at least 75 wt. % of polylactic acid (PLA), wherein the PLA contains a physical blend of at least two PLA polymers, i.e. at least one PLA polymer A and one PLA polymer B, wherein at least 80% of PLA polymer A is produced from 80% D,D-lactide and at least 80% of PLA polymer B is produced from 80% L,L-lactide, and wherein the ratio of D-lactic acid to L-lactic acid in the PLA blend is between 0.4:0.6 and 0.6:0.4.
Abstract:
Substrate in the form of a flat element comprising a composition containing modified polylactic acid and containing the following components: (1) at least one (co-)polymer based on at least one lactic acid; (2) at least one compound comprising at least one carbodiimide group; (3) optionally at least one compound having at least one epoxide group additionally containing at least one ester group and/or at least one aromatic group; (4) at least one phosphorus-containing compound and (5) optionally additives and/or fillers.
Abstract:
The invention relates to a composite for production of an acoustic membrane, wherein the composite comprises an internal carrier layer and at least two adhesive layers on the two surfaces of the carier layer, and wherein the carrier layer is a layer of a polyaryl ether ketone film; and also to a corresponding membrane for acoustic transducers.
