DARLYN 1100 CB & ULTRACHEM
CB or Chemical Barrier was developed for superior corrosion resistance. A multilayer PTFE cast
film is thermally and chemically welded to DARLYN 1100 and ULTRACHEM assuring an even
greater protection from corrosion due to exposure in the most extreme conditions. This
isotropic film (identical physical properties in all directions) is built up through multiple
operations assuring a uniform thickness, nonporous, chemically inert barrier. Further, when
combined with the DARLYN and ULTRACHEM isotropic fabric, the result is a uniform membrane
which can flex without stress concentrations, distributing the load equally throughout the belt.
HIGH TEMPERATURE APPLICATIONS
■
Superior strength retention, even after repeated flexing.
■
Fast, easy field splicing
■
Outstanding corrosion resistance
■
Less than 1/4 the weight of 100% fluoroelastomer fabrics, resulting in lower installed costs
ULTRACHEM fluoroplastic
coated fiberglass fabric
FLEXON-700 A composite belt designed
to provide continuous reliable service at
700°F (371°C). A tightly woven fiberglass
insulation is thermally bonded to the
FLEXON material. This composite design
provides insulating properties at elevated
temperatures and prevents separation of
the insulation.
