    Clean Room Lightweight Melamine Foam Pipe Insulation

    Limit contaminants in clean rooms and sanitary environments. The jacket on this insulation meets ISO Class 5 and Fed. Spec. Class 100 clean room standards, so it won’t shed particles. It’s also washable, making this insulation good for stainless steel process piping and clean steam distribution systems that undergo frequent cleaning. In addition, the lightweight melamine won’t overload supports on overhead piping and long runs.
