发明名称 THIN-WALLED ARTICLE OF PROPYLENE RESIN FOR SUBSTRATE OF RELEASING PAPER
摘要 PURPOSE:To provide the subject thin-walled article having excellent heat- resistance, suitable as a stiff substrate for releasing paper and consisting of a thin-walled article of a propylene homopolymer containing a specific amount of an inorganic filler and having specific physical properties. CONSTITUTION:The objective thin-walled article having a foaming ratio of 1.2-3.5 (preferably 1.2-3.0), a draw ratio of 1.5-7 (preferably 1.5-6) and usually a thickness of 50-1,000mum (preferably 60-500mum) is produced by compounding (A) 100pts.wt. of a propylene homopolymer having a melt flow index of preferably 2.0-15g/10min (especially 2.0-10g/10min) with (B) 3-20pts.wt. of an inorganic filler such as mica, calcium carbonate, clay or precipitated barium sulfate.
