Kynar® PVDF Sampling Bag 10 liter with PTFE fitting (10 bags)
The Kynar® PVDF sample bags are made of 3mil Kynar® PVDF (PolyVinyliDene Fluoride) film. Kynar® PVDF is transparent, tough, durable, and has excellent chemical resistance because of its unique properties.
The bags are delivered with an eyelet and the patent-pending single 2-in-1 fittings that combine the valve and septum into one.
Kynar® PVDF 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 of Kynar® PVDF foil
Kynar® PVDF 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).
Kynar® PVDF 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.
