Specifications and Details of Kynar Bag
These bags manufactured by using polyvinylidene fluoride (PVDF) film.These bags manufactured by using polyvinylidene fluoride (PVDF) film. The commercial name PVDF is Kynar; hence, these bags are also known as a Kynar bag worldwide. It is robust, sturdy, and has excellent resistance to chemicals like acids, bases, halogenated solvent, hydrocarbons, alcohols, salts, etc. These bags are also resistant to UV radiations, moisture, and Heat. The maximum operating temperate is 73-degree Celsius.
The Kynar gas sampling bags come in a variety of sizes ranges from 500ml to 10 liters. It can be customized up to 1000 liter capacity. The thickness of the PVDF film is 3mil or 0.0762mm. The dimensions of the bags vary as per their allocated capacity. It is heat-sealed adequately from all four sides to prevent leakage. Generally, the Polypropylene (PP) valve used in the Kynar bag, but customization can be possible as per client requirement. It is 2 in 1 combo valve with 7mm hose for sample inlet.
