PTFE Dispersions are milky-white aqueous dispersions of stabilized minute PTFE particles designed for release coatings and impregnation of media. PTFE is extremely resistant to weathering and can be used for architectural applications where 20 years and longer service is required. PTFE impregnation improves the chemical stability, heat resistance, chemical resistance, low friction properties, release properties, and dielectric characteristics of the media. PTFE Dispersions are used for impregnating yarns, packing materials, glass cloth and other media, release coatings for cookware and industrial applications, circuit board laminates, belting, filter bags and media and flexible ductwork. If you want to know more about polytetrafluoroethylene PTFE and bulk cost, please do not hesitate to contact FLUORINCHEM PTFE fluoroplastic resin manufacturer.

Conventional dip or flow techniques can be used for coating or impregnating high temperature fabrics, fibers, and other products with PTFE Dispersion. It also can be used in coatings for metal surfaces applied by spray, roll coating, or curtain coating techniques. Other solid or liquid ingredients can be added to PTFE Dispersion to provide specific processing or finished product behavior.
PTFE Dispersion must be properly stored to maximize the stability of the dispersion. The PTGE dispersion must be protected from freezing, which will cause irreversible settling. The optimum storage temperature range is 7–24 °C (45–75 °F). If the PTFE dispersion is to be stored for extended periods, lower-temperature storage is desirable. For optimal performance, PTFE Dispersion should be gently mixed or rolled monthly and prior to use.
