Abstract

PURPOSE: To carry out the titled crosslinking within a short time, by immersing the tube or pipe in hot water or steam at a temperature lower than the softening point of the polyolefin and introducing the same water or steam into the tube or pipe from an end.
CONSTITUTION: A long tube or pipe 1 consisting or a water-crosslikable silicone- grafted polyolefin is wound arouns a drum 2 and immersed in, for example, hot water 3 (70°C) or steam. Then, while air is drawn from one end 4 of the pipe or tube by a vacuum pump, air-mixed hot water or steam at a temperature which is below the softening point of the polyolefin is introduced continuously into the tube from the other end. As compared with conventional methods consisting of immersing in hot water or steam, this crosslinking method provides much faster curing.
