Section XXV Miscellaneous & Multipurpose Compounds Miscellaneous & Multipurpose Compounds 111 Claude Bamberger Molding Compounds Corp.: BAMBERKO ULTIMAX Purging Compound: Hi-molecular Ultimax is formulated to purge all types of engineering and thermoplastic materials. It will not damage or scratch injection cylinders and extrusion barrels. It is recommended for use in swift color or resin changeovers and to clean equipment of carbonized residue Ultimax will not melt completely, and is designed to purge hi-heat and high temperature engineering plastics and other difficult purging jobs. While most purging compounds work best in a 350-450F (176 to 230 Celsius) range, Ultimax is designed for use in purging high heat engineering plastics in the 450-525F (230 to 275 Celsius) range. Compared to other purge compounds, Ultimax will clean equipment more quickly and more efficiently in a considerable saving of a manufacturer’s ‘downtime’. In most instances it will work without the need to change temperatures. Produced from prime resin, Ultimax is recommended for use in FDA approved food contact items as well as for manufacturing medical products Ultimax minimizes unpleasant odors and fumes, making it environmentally friendly. 112 Plastics Additives Buckman Laboratories, Inc.: Successful Applications of BUSAN 11-M1 in Plastic and Rubber Compounds: Busan 11-M1 is a multifunctional barium metaborate pigment used as a fire retardant, fungus inhibitor, and UV light stabilizer in polyvinyl chloride and other plastic and rubber compounds. Typical of PVC products compounded with Busan 11-M1 are automotive tops and trims, inflatable buildings, pond liners, roofing, and plastic-coated fabrics such as tarpaulins and awnings. The effectiveness of Busan 11-M1 as a fire retardant is restricted to polymers containing a halogen donor or to which one can be combined. Bromine compounds are somewhat more effective than other halogens but chlorinated paraffin and chlorindic anhydride have performed very well. Experience has indicated that Busan 11-M1 can replace antimony trioxide in most fire retardant formulations. Subject to the degree of halogenation and the degree of fire resistance required. Replacement can be 50 to 100%. In addition to providing after-flame resistance, Busan 11-M1 also reduces the time of afterglow (i.e., flameless combustion) and in many formulations reduces the amount of smoke generation. Other advantages over antimony trioxide are the low refractive index of Busan 11-M1 which prevents interference in tint and dye requirements and the fungicidal activity that characterizes barium metaborate. Busan 11-M1 is well known as a fungicide for coatings and plastics. Its advantages in plastics and plastic-coated fabrics over conventional organic fungicides are longevity in the film and efficacy unaffected by UV exposure. Products particularly susceptible by fungal disfigurement and/or deterioration include pond liners, tarpaulins, awnings, and shower curtains. Busan 11-M1 provides UV light stabilization to most polymeric materials including PVC and glass-reinforced polyester. Its durability in these materials is outstanding and thus extends the performance of UV absorbers.
