Abstract
Polymer compositions contain a polyoxymethylene polymer combined with a plasticizer and impact modifier. In accordance with the present disclosure, the plasticizer can have a relatively high boiling point, such as greater than 300° C. In one embodiment, the plasticizer may comprise a dibenzoate or hexanoate. Plasticizers made in accordance with the present disclosure are resistant to evaporative loss while increasing physical properties. The polymer composition can be molded into various different articles, such as tubes, fasteners, clips, cable ties and sporting goods.
