Beschreibung
Zusammenfassung:	Heat insulating material of the syntactic type comprising a filler of hollow glass microballs embedded in a matrix, and fabrication method. The matrix is selected from the family of elastomers such as natural rubber, polychloroprene, styrenebutadiene copolymers (SBR), butadiene-acrylonitrile copolymers (NBR), polynorbornenes, ethylene-propylene-diene monomers (EPDM), butyle rubbers and the like. For the fabrication of the material, hollow glass microballs are incorporated into a matrix in liquid or pulverulent phase, and the microballs and the matrix are mixed together without applying large shearing efforts and finally a cross-linking treatment is operated. The material is usable particularly for insulating underwater pipelines for the transportation of gas or oil from off-shore oil fields or urban heating conduits.
