Abstract

PURPOSE: To obtain a pipe-like polyolefin foam formable into even a small-diameter pipe, having a low shrinkage when exposed to a high-temperature atmosphere, by joining both ends of a bent crosslinked polyolefin foam in the long direction with heat in a compressed state.
CONSTITUTION: The chemically crosslinked polyethylene foam sheet 1 10mm thick having a density of 0.03g/cc is passed through the nip 4mm between the rolls 2a and 2b, then the nip 2mm between the rolls 2b and 2c, and compressed in the thickness direction. The compressed sheet 1 is then passed through the trumpet- shaped molding device 3 having the inside diameter of 18mm, bent in the shape of a cylinder, and joined by blowing hot air from the nozzle 4 on the both ends of the sheet 1. The joined sheet is passed through the driving belts 5a and 5b to fix the joined part completely, thus giving the pipe-like polyethylene foam 6 having the inside diameter of 12mm and a wall thickness of 10mm.
