Americhem says they are well-suited for use in sanitary applications for the kitchen and bathroom, and in other areas. It is targeting Asian markets in particular, but the products do also comply with regulations in Europe and the US. Their active ingredient suppresses the growth of bacteria, algae, fungus, mould and mildew. The masterbatches possess excellent compatibility
with transparent polymers like polycarbonate, acrylics and styrenics, says Tom Ellefsen, chief executive of Life Material Technologies (and an ex-Microban director). “In addition to sanitary ware, our antimicrobial additive technologies are appropriate as antifungal agents in high-temperature and transparent polymers, as well as plastics used outdoors. Products are also available for nylon and polyester fi bres as well as products that allow for an ultra-low let-down rate.”
Vaman Kulkarni is Americhem’s expert on antimicro- bials in Cuyahoga Falls, Ohio. He says the company’s nShield range now includes organic and inorganic materials based on various technologies and from various companies. Its original focus was on silver- based products for polyester and polyamide fi bres with processing temperatures of over 280°C; but it has since expanded its market coverage. “The key thing we bring is our ability to create very fi ne dispersion of the additive, which is very critical in fi bres, especially those
