Abstract: The present application is a composition including abase resin comprising between about 4% and about 15% acrylic acid monomer and an oligomer additive comprising (a) one of an acrylamide or meth(acrylamide) copolymer and (b) a high glass transition temperature monomer. The oligomer additive has a molecular weight range of between about 20,000 and about 1,000,000 and a glass transition temperature of between about 70° C. and about 115° C. The composition has a blending ratio of base resin to oligomer additive of between about 7 to about 30 parts per hundred of resin.

Abstract: Stretch-release adhesives are provided which are derived from mixtures comprising: a) a tackified styrenic block copolymer comprising: i) one or more tackifiers; and ii) one or more styrenic block copolymers; wherein the weight ratio of i) to ii) is not more than 1.0:2.0; and b) one or more (meth)acrylate polymers. In some embodiments, the weight ratio of a) to b) is between 0.4:1.0 and 5.0:1.0 and in some between 1.0:1.0 and 3.9:1.0. In some embodiments, the one or more styrenic block copolymers comprise at least 90 wt % linear block copolymers. In some embodiments, the tackifiers are miscible with rubbery blocks of the styrenic block copolymers and not miscible with the (meth)acrylate polymers. In some embodiments, the mixture is crosslinked. Tapes comprising stretch-release adhesives according to the present disclosure are also provided.

Abstract: A non-halogen flame retardant adhesive composition and tape comprises the same are disclosed. The non-halogen flame retardant adhesive composition comprises an adhesive and a flame retardant composition. The flame retardant composition comprises a phosphoric acid ester compound and a flame retardant material selected from one or more elements of a group consisting of melamine cyanurate, melamine pyrophosphate and phosphinate salt. The ratio of the adhesive and the flame retardant composition is in a range from 1:0.7 to 1:1.2, and the non-halogen flame retardant adhesive composition has 180 degree peeling strength above 1.0 kg/in based on ASTM-D3330 and achieves a UL 94 VTM flame resistance capability.
