Polyvinyl chloride resin composition
PURPOSE: The present invention provides a polyvinyl chloride resin composition which is superior in heat stability and processability and has less elution from the composition. CONSTITUTION: a polyvinyl chloride resin composition comprising 100 parts by weight of a polyvinyl chloride resin, 10 to 120 parts by weight of di(2-ethylhexyl)terephthalate, and 0.5 to 20 parts by weight of epoxidized vegetable oil having a peroxide number of 5 or less.
1. A method for producing a medical instrument by forming a polyvinyl chloride resin composition which comprises 100 parts by weight of a polyvinyl chloride resin, 10 to 120 parts by weight of a plasticizer consisting essentially of di(2-ethylhexyl)terephthalate, and 0.5 to 20 parts by weight of epoxidized vegetable oil having a peroxide number of 5 or less; wherein plasticizers other than di(2-ethylhexyl) terephthalate are either not present in the composition or are present in the composition only in trace amounts.
2. The method according to claim 1 , wherein the composition further comprises 0.05 to 10 parts by weight of silicone oil.
3. The method according to claim 1 , wherein the instrument is a medical tube or a medical bag.
