BASF's new Ultraform® E3120 BM allows hollow objects with demanding requirements to be made of polyoxymethylene (POM) by means of extrusion blow molding. When compared to containers made of polyethylene (PE), they display considerable better barrier properties against gases such as oxygen, hydrogen and carbon dioxide. Ultraform E3120 BM is resistant to many types of media such as alcohol, oil and hydrocarbons. It can be sterilized with hot steam, is easy to process, translucent and chemical-resistant
A very high melt stiffness makes the material ideal for processing by means of extrusion blow molding. Due to the optimized crystallization behavior the material offers a wide processing window, so that the blow molding process can be cost-efficiently automated. The high stretchability of the plastic melt gives access to applications with thin-walled sections. Since this translucent material accurately replicates the mold surfaces and is easy to dye, bottles for nail polish removers and other cosmetics, cans for solvents and paints, tanks for coolants and brake fluids as well as pressurized containers such as spray cans now can be smartly designed. Another option would be to add barrier layers to co-extruded films. The hollow objects made of the new POM grade are cost-effective to manufacture and actually weigh less than containers made of metal or glass. Furthermore, BASF experts can support customers when it comes to the design and construction of blow molded parts.
