Kynar® Bag CELScientific
Kynar® Bag
CEL Scientific Kynar gas sampling bags are made of 3mil or 4mil Kynar PVDF
(PolyVinyliDene Fluoride) film. Kynar is transparent, tough, durable, and has
excellent chemical resistance because of its unique properties. We can offer Kynar
bags in all sizes up to 1000L. All of our stock bags feature an eyelet and our
patent-pending single 2-in-1 fittings that combine the valve and septum into one.
We offer polypropylene, stainless steel, and PTFE fittings (please specify
preference when ordering). Contact us for custom sizes and requirements.
More about Kynar:
Kynar® is the registered trademark of Arkema Inc.'s polyvinylidene fluoride
(PVDF) resin. PVDF is a fluorinated polymer, or fluoropolymer, that is dissolved,
dispersed, foamed, and melt processed for use in a wide range of industrial and
architectural applications.
Strength and Toughness: Kynar® is extremely strong and tough by offering
an ambient temperature tensile strength at yield of 35-55 MPa (5,000-8,000 psi)
and an unnotched impact strength of 800-4270 kJ/m (15-80 ft-lbs/in).
Chemical Resistance: Kynar® resins are resistant to a wide range of chemicals,
including most acids and acid mixtures, weak bases, halogens, halogenated
solvents, hydrocarbons, alcohols, salts, and oxidants. At ambient temperatures,
PVDF homopolymers are generally resistant to chemicals with a pH up to 12. Click
