Kynar - PVDF Sampling Bag – 0,5 Liter PP Fitting – 3mil (pkg 10)
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).
Chemical Resistance
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.
