Abstract:
1. A flexible tube comprising a thermoplastically processible composition with a heat conductivity greater than 0.5 W/mK, comprising: a thermoplastically processible molding material selected from the group consisting of TPE-U (thermoplastic elastomer on a polyurethane base), TPE-A (thermoplastic elastomer on a polyamide base), TPE-E (thermoplastic elastomer on a polyester base), TPE-O (thermoplastic elastomer on a polyolefin base), styrene block copolymers, EPDM/PE-mixtures, EPDM/PP mixtures, and PEBA (polyether block amide); and inorganic filler particles, wherein said inorganic filler particles comprise heat-conducting pulverized metals selected form the group consisting of aluminium, copper, and silver, said inorganic filler particles have a trimodal particle size distribution, and said composition is a flexible thermoplastically processible composition in that said tube has a bending radius less than 5 cm without fracture or kinking, a fracture elongation greater than 20% and a bursting pressure of greater than 20 bar.
