Fluoroseal joint sealant tape is manufactured from 100% expanded PTFE. The material offers good creep and cold flow resistance. Fluoroseal possesses excellent chemical resistance.  It is also weather resistant and will not deteriorate with age. The sealant tape is supplied with a self adhesive strip and is available in a range of widths from 3mm (1/8”) to 25mm (1”).  It conforms easily to irregular shapes and can be pushed into narrow openings effortlessly.  As a guide the width of the tape selected should be between one third and one half of the flange contact area.
