Abstract

Crosslinkable compositions are developed based on an elastomer-containing powder or pelletized material, for instance composed of recycled material such as used tyres, including specific additives, and to elastomer compounds and articles obtainable therefrom, and to methods for the production thereof. The crosslinkable composition includes (a) a powder or pelletized material including at least one elastomer, (b) at least one poly-C5-C15-alkenamer, (c) at least one liquid poly butadiene, and (d) at least one crosslinking agent.

• C08J 3/24 - Crosslinking, e.g. vulcanising, of macromolecules

Abstract

Compacts synthesized by cross-linkable material based on an elastomer-containing powder or pelletized material and a method for producing these compacts show a very good suitability in the further processing of these compacts to form crosslinked elastomer compounds and shaped bodies and for the substitution of raw rubber or raw rubber-containing compositions.

IPC Classes  ?

• C08L 17/00 - Compositions of reclaimed rubber
• B29C 43/00 - Compression moulding, i.e. applying external pressure to flow the moulding materialApparatus therefor
• B29C 43/52 - Heating or cooling
• B29K 21/00 - Use of unspecified rubbers as moulding material
• B29K 23/00 - Use of polyalkenes as moulding material
• B29K 105/00 - Condition, form or state of moulded material
• B29K 105/26 - Scrap
• B29K 507/00 - Use of elements other than metals as filler
• B29K 509/02 - Ceramics

Abstract

The present invention relates to a method for producing pressed products made of a crosslinkable material based on an elastomer-containing powder or granulate, in particular a recycled material such as scrap tyres. The method also relates to the pressed products obtained therefrom and to the furtlier processing thereof. The pressed products are very well suited for further processing to form crosslinked elastomer compounds and moulded bodies formed therefrom, and for the substitution of raw rubber or compositions containing raw rubber.

IPC Classes  ?

• B29B 17/00 - Recovery of plastics or other constituents of waste material containing plastics
• C08L 19/00 - Compositions of rubbers not provided for in groups
