Durlon® Virgin PTFE gasket material is a high performance skived pure PTFE product designed for use in piping and equipment in chemical and other general industrial applications where resistance to highly aggressive chemicals (including hydrofluoric acid) is required.
Not to be confused with processed or mechanical grade PTFE, Durlon® Virgin PTFE is a higher grade, pure material with better physical properties. Virgin PTFE retains better flexibility in low temperature applications and exhibits good electrical insulation and high dielectric properties. Durlon® Virgin PTFE is suitable for food contact whereas most mechanical grade PTFE’s are not.
