This ozone compatibility chart shows how ozone relates to other materials when exposed to them, please remember that this chart is only meant to be for reference and as such is a general guide. This page contains a guide to selecting O-ring materials based on chemical compatibility requirements. The chemical compatibility data can be presented in one of two ways. First, you can select a specific O-ring material to view its compatible chemicals. Or second, you can select a specific chemical to view all its compatible O-ring materials.
What Chemicals are Compatible with PTFE and Teflon®*? PTFE is the most versatile plastic in terms of chemical compatibility Highly resistant to most acids, alcohols, detergents and solvents Ideal for use with reactive and corrosive chemicals Neural tissue compatibility of Teflon as an implant material for microvascular decompression.
304L stainless steel, a low-carbon variant of 304 steel, is used for ultra-high vacuum systems. 316L stainless steel a low-carbon and low-magnetic stainless steel, used in accelerator technologies.
(foreign object debris/damage) if left in layup. Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints , and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals. Teflon can be machined to close tolerances, letting Vanderveer Industrial Plastics deliver the exact PTFE / FEP machined parts you need. Vanderveer Plastics' PTFE machined parts meet several ASTM requirements, including ASTM D 1710 or ASTM D 4894, for military and commercial specifications. 2018-07-25 · Contact Ozone Solutions to determine if your material is compatible.

Or second, you can select a specific chemical to view all its compatible O-ring materials. Ozone Material Compatibility. The following chart provides general guidelines on ozone material compatibility.
B – Good. PTFE/Teflon™ Description: Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and is a fluorocarbon solid. It has a high-molecular-weight, and consists only of carbon and fluorine. PTFE is best known by the brand name Teflon™ by Chemours. PTFE was discovered by DuPont in 1938.
Before handling or using neat biodiesel (B100) contact the equipment vendor to determine compatibility with fatty acid methyl esters. Teflon, Viton, and Nylon have very little reaction to biodiesel and are among the Non-production materials such as Teflon, Airweave Breather and the bag itself would be considered F.O.D. (foreign object debris/damage) if left in layup. Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints , and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals.

The original PTFE resin was invented by DuPont in 1938 and called Teflon®. PTFE is a crystalline polymer with a melting point of about 621° F (327° C). Nonstick: Few solid substances adhere permanently to a Teflon™ industrial coating.
Actual performance depends on the environment (dry or moist air, water, concentration of ozone, whether the materials have been modified for ozone service, etc.) and application (polycarbonate is stable in the presence of ozone but yellows over time which reduces its utility where
Several in vivo and in vitro studies demonstrated the good tissue compatibility of Teflon [7, 8, /0-13, 23,24,25,28].The mechanical properties of shredded Teflon favor it over several other materials as implants in microvasular decompression (MVD) operations for treatment of trigeminal neuralgia, hemifacial spasm, disabling positional vertigo, glossopharyngeal neuralgia, and spasmodic
material for the pump seals. As corrective actions, the licensee is performing a material compatibility review and will restrict the use of Teflon®. The licensee replaced the affected pump seals prior to startup. In addition to the recent experience at Fort Calhoun, the potential for Teflon® material
2021-04-22 · Published information on the compatibility of materials with vapor-phase hydrogen peroxide (VHP), low-temperature peracetic acid vapor gas plasma sterilization (Plazlyte), and other new processes is limited. 3 However, one common theme is a shift toward processes that are more oxidizing.
