There is no more demanding application of a polymer than medical uses. Polysulfone engineering resins combine high strength with long-term resistance to repeated steam sterilization. These polymers have proven successful as alternatives to stainless steel and glass.
Medical grade polysulfones are biologically inert, display unique long-life under sterilization procedures, can be transparent or opaque in any color and are resistant to most common hospital chemicals.
