Barium Metaborate, Busan

There are no data available to me on barium metaborate application in WPC materials. Though it might be considered for this purpose, its required effective level might reach 5-10%. This can be affordable only if besides its antimicrobial effect, barium metaborate would add more value to the composite material, due to its other useful properties.

This zinc borate is a more effective flame retardant and smoke suppressant than barium metaborate (Busan 11M1).43 For example, in flexible PVC, a combination of antimony trioxide and the zinc borate results in much better fire test performances than the antimony trioxide and barium metaborate combination (Table 9.4). In contrast to flexible PVC, this zinc borate alone improves both fire retardancy and smoke suppression in rigid PVC.48...

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. 

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.
