CHLORINATED VINYL CHLORIDE RESIN COMPOSITION FOR EXTRUSION MOLDING |
摘要 |
<p>[Problem] The present invention provides a chlorinated vinyl chloride resin composition for extrusion molding, which can permit long-time stable extrusion molding, particularly, long-time stable extrusion molding of a sash or other long profile having a complicated cross-sectional shape, and which obtains a fire-resistant molded product which is expanded on heating to form a hard heat insulating layer having high mechanical strength. [Solution] A chlorinated vinyl chloride resin composition for extrusion molding, characterized by: containing 100 parts by weight of a chlorinated vinyl chloride resin, 3 to 300 parts by weight of a thermally expandable graphite, 3 to 200 parts by weight of an inorganic filler and 20 to 200 parts by weight of a plasticizer; and containing no phosphorus compound (excluding phosphate plasticizer). A chlorinated vinyl chloride resin having a chlorine content of 60 to 72% by weight can be used as the resin component for extrusion molding.</p> |
