  • Polyacetal lighter body resin
    Patent number: 4942208
    Abstract: A novel polyacetal resin blend provides for dimensionally stable rib-reinforced tubular bodies upon injection molding of the blend. The blend comprises a major proportion of an oxymethylene copolymer having a melt index of 27.0 grams/10 minutes and a minor proportion of an oxymethylene copolymer having a melt index of 9.0 grams/10 minutes to provide hydrolytic stability to the molded article. Each of the oxymethylene copolymers are formed from recurring oxymethylene units interspersed with alkylene oxide units in which the alkylene group contains at least two adjacent carbon atoms. The blend is particularly useful in forming cigarette lighter bodies.
