Abstract:
PROBLEM TO BE SOLVED: To produce a foaming material comprising an aromatic polyester and a polyester blend, foamable by a stable foaming process and containing fine and uniform closed cells. SOLUTION: A chain-extending concentrate is used in production of the foaming material comprising the aromatic polyester and the polyester blend. The chain-extending concentrate comprises an ethylene-acrylate copolymer, a high-temperature thermoplastic resin and a multifunctional compound. The preparation process consists of two steps; (1) mixing and melt blending of the multifunctional compound and the HT thermoplastic resin into a matrix of the ethylene-acrylate copolymer in a closed-type mixer and (2) extrusion of the mixture at a temperature below the melting point or reaction temperature of the multifunctional compound.

Abstract:
The insulating piece (11) has the form of a sheet or a hollow cylinder with an external wall (12) and an internal wall (13) from which elastically deformable projections (14) extend. According to the invention, the insulating piece can be applied to a given range of tube external diameters, whereby the hollow cylinder is made from an elastomeric foam based on rubber with a density of 30 to 120 g/dm , the projections (14) are formed in one piece therewith and the cylinder is provided with air channels (16, 17), essentially parallel to the axis thereof, which leads to an unexpected reduction in the apparent heat conductivity of the insulation piece.
