Buckman Laboratories, Inc. Successful Applications of BUSAN 11-Ml in Plastic and Rubber Compounds  

Busan 11-Ml 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-Ml are automotive tops and trims, inflatable buildings, pond liners, roofing, and plastic-coated fabrics such as tarpaulins and awnings. 

The effectiveness of Busan 11-Ml 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-Ml 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-Ml 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-Ml which prevents interference in tint and dye requirements and the fungicidal activity that characterizes barium metaborate.
