PFA and Teftek® are resistant PTFE, FEP, PFA and Teftek® explained PTFE is part of a closely related family of fluoropolymers. At times, it is mistaken that PTFE is the one and only fluoropolymer, when FEP, PFA and Teftek® also can be used under the appellation. Though all of the fluoropolymers can be alogued in the same family, they vary in regards to thermal and mechanical properties

An economical alternative to Viton® fluoroelastomer foam, these semi-rigid nylon foam sheets offer good resistance to a wide range of chemicals.
Such resistance however, is a function both of temperatures and concentration, and there are many reagents which can be handled for limited temperature ranges and concentrations. In borderline cases, it will be found that there is limited attack, generally resulting in some swelling due to absorption. There are also many cases where some attack will occur under specific conditions, but for
Parker''s 221FR hose is a transportation hose used for marine fuel and engines that provides fire resistance for gasoline and fuel systems. The 221FR hose is manufactured and tested to meet many agency approvals, such as: USCG, ABS, DNV, LR, and MSHA, for reliability. Sizes range from ¼” to 7/8” in diameter to fit the requirements of
The use of FEP jacket will limit the stability to a temperature range lower than that of the PFA that will remain stable until +260° C,376/5000 having also the property of superior resistance to abrasion and pressure. Encapsulated gaskets of FEP or PFA with Silicone and FKM, are used as gaskets in both O-ring, square, rectangular, oval and
within machinery, minimize the “wear and tear,” and improve energy consumption. PFA is generally used for plastic lab equipment because of its extreme resistance to chemical attack, optical transparency, and overall flexibility. PFA is also often used as tubing for handling critical or highly corros ive processes. Other appliions for PFA are as sheet linings for chemical equipment
30/3/2017· OMEGA-GLYDE ® PTFE Sheet, Rod and Tube is resistant to practically every chemical and has a surface as slippery as ice on ice to which no substance will adhere. Chemically inert up until high temperatures and pressures including being able to perform in harsh UV conditions for long periods, OMEGA-GLYDE ® PTFE is an ideal gasket material. It is completely non-toxic, has unmatched anti
PFA Super Long Length Hose. ProFlex™ PFA offers super long lengths, excellent chemical resistance, and flexibility. PFA has the same chemical and temperature resistance as PTFE and much better flex life than FEP. ProFlex PFA open pitch spiral convolutions aid in draining, flushing, and cleaning of the hose. ProFlex industrial grade PFA was designed for customer appliions that don''t
PFA fluoropolymer resins and Tefzel® fluoropolymers. These materials can be used to make a variety of articles having a coination of mechanical, electrical, chemical, temperature, and friction-resisting properties unmatched by articles made of any other material. Commercial use of these and other valuable properties coined in one
together, e.g. hydraulic seals and gaskets, diaphragms, hoses and roller-skate and skateboard wheels. In all appliions, consideration should be given to hydrolysis and limited heat resistance. 4 EPR/EPDM (Ethylene-Propylene) These rubbers are mainly available in two structures – as the copolymer (EPR), or as the terpolymer (EPDM). The properties for both types of …
