LOW DISTORTION SILANE-MODIFIED OLEFINIC RESIN MOLDING AND LOW SHRINK SILANE-CROSSLINKED OLEFINIC RESIN MOLDING AS WELL AS MANUFACTURING METHOD FOR THESE, AND HOT WATER RUNWAY TYPE HEATING RADIATOR PANEL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a silane-crosslinked olefinic resin molding which has the low moisture content and the recyclability for the product. SOLUTION: The low distortion silane-modified olefinic resin molding has a shrink ratio, by a hot water treating test as the following, of less than 1%, and a gel fraction of less than 50%, and this molding is manufactured by heat treating a silane-modified olefinic resin molding under a dry atmosphere with a humidity of 80% or less. The low shrink silane-crosslinked olefinic resin molding is formed by crosslinking reaction of this low distortion silane-modified olefinic resin molding in the presence of water. The hot water runway type heating radiator panel material uses this low distortion silane-modified olefinic resin molding and this low shrink silane-crosslinked olefinic resin molding. The above hot water treating test comprises the hot water treatment for the above molding to be kept in a hot water of 80°C and for 8 hours, and thereafter the measuring of the dimensions of the molding respectively before and after the hot water treatment test and finally the determining of a shrink ratio(%) of a dimension Lxafter the hot water treatment to a dimension Lobefore the hot water treatment, by using the formula: a shrink ratio(%)=(Lo-Lx)/Lo×100.
