Abstract
A method of manufacturing crosslinked polyolefin foams, with a very thin closed cell structure, which consists in heating a mixture of a polyolefin, a crosslinking agent and a foaming agent at a temperature higher than that of decomposing said foaming agent or irradiating a mixture of a polyolefin and a foaming agent by ionizing radiation whereby said polyolefin mixture is crosslinked, and heating said mixture thus treated to a temperature above the decomposition temperature of said foaming agent, each agent having a temperature of thermal decomposition more high that the melting point of said polyolefin, characterized in that said foaming agent has an average particle size of 10 to 30 microns in diameter.
