Modified PTFE Bags
Bags made from modified PTFE (Polytetrafluoroethylene) offer a low cost alternative to FEP and PFA. Modified PTFE bags is translucent and has many of the same properties of the higher priced PFA and FEP bags.
More Details on Modified PTFE Bags Modified PTFE is a chemically modified version of PTFE with higher permeation resistance, lower creep, smoother surfaces and better high-voltage dielectric properties. Modified PTFE has reduced porosity, improved tensile strength while offering a high degree of weldability. Modified PTFE has the same performance characteristics of standard PTFE.
There are different versions of Modified PTFE ranging from partially modified to fully modified. (This speaks to the amount of a PPVE comonomer that has been added) All versions offer excellent chemical resistance over a wide thermal range as well as excellent anti-stick performance. Modified PTFE is the lowest cost fluoropolymer and is often used as a replacement for more expensive FEP and PFA in thin film applications.
Benefits of Modified PTFE Bags
