> Chemical and corrosion resistance > Tight tolerance requirements How Our Meldin® Family Started and Evolved Historically, Omniseal Solutions (formerly Dixon Industries Corp.) focused on the production of fluoropolymer compounds. Beginning in 1957, our well-known Rulon® solution was used in a new plastic saddle design and was quickly adapted for wider use. In the 1970s, we developed the Meldin® 2000 product line (based on thermoset polyimide) primarily as a filler for Rulon®. We launched the Meldin® family of thermoplastic products in 1980, starting with the Meldin® 1000 and 5000 series. The...
