USE OF A COMPOSITION FOR THE MANUFACTURE OF A FOAMED ARTICLE

The present invention relates to the use of a composition comprising from 60-98 wt. % of polypropylene, from 2-40 wt. % of aromatic polycarbonate and from 0.1-10 wt. % of compatibiliser for the manufacture of a foamed article, wherein the compatibiliser is a BAB or AB type of block copolymer comprising a polypropylene block A and a polyester or polycarbonate block B, or wherein the compatibiliser is a graft copolymer of the type ABn having a polypropylene backbone A and polyester or polycarbonate block(s) B grafted thereon, with n being at least 1, and wherein the polyester or polycarbonate blocks B have an average M/F ratio from 2-25, wherein M is the number of backbone carbon atoms in the polyester or polycarbonate not including carbonyl carbon atoms, and F is the number of ester or carbonate groups in the polyester or polycarbonate block, and wherein the wt. % is based on the sum of the amount polypropylene, polycarbonate and compatibiliser.

Foamable, insulating-layer-forming multi-component composition having improved storage stability and use of the same

A foamable, insulating-layer-forming multi-component composition contains alkoxysilane-functional polymer, insulating-layer-forming fire-protection additive, blowing-agent mixture, cross-linking agent, and a flame-protection agent that is miscible in water or another compound that is miscible in water. The individual ingredients of the blowing-agent mixture are separated from one another to ensure inhibition of reaction prior to use of the composition, and the cross-linking agent is separated from the alkoxysilane-functional polymer to ensure inhibition of reaction prior to use of the composition. The foamable, insulating-layer-forming multi-component composition can be used as a foam-in-place foam or for production of molded blocks.
