Abstract: A thermally expandable composition, including: (a) at least one polymer P, cross-linkable by a free-radical initiator; (b) at least one acrylate A; (c) at least one free-radical initiator; (d) at least one blowing agent; and (e) at least one surfactant, whereby the surfactant is a sulfonate salt. The thermally expandable composition is able to provide sufficient expansion behaviour when used in the form of a thin layer and is especially suitable for baffle and/or reinforcement elements.

Abstract: A thermally expandable composition, including at least one polymer, cross-linkable by peroxide, at least one peroxide, preferably at least one antioxidant, at least one chemical blowing agent, and at least one activator, wherein the activator includes at least one compound selected from formula (I), wherein radicals R1 and R4 represent hydrogen atoms or monovalent alkyl radicals with 1 to 10 carbon atoms which optionally include oxygen atoms; R2 and R3 represent hydrogen atoms or monovalent alkyl radicals with 1 to 10 carbon atoms which optionally include oxygen atoms, nitrogen atoms, and/or aromatic moieties or R2 and R3 together form a divalent alkyl radical with 1 to 10 carbon atoms which optionally includes oxygen atoms, nitrogen atoms or aromatic moieties. The composition shows excellent properties in terms of expansion stability over a wide temperature range, can be expanded at temperatures below 150° C. and is suitable for baffle and/or reinforcement elements.
