Principle
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen flows outside.
Standards
This test instrument conforms to the following standards:
ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB00082003
This test instrument is applicable to the determination of oxygen transmission rate of:
| Basic Applications | Films
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others |
|---|
Sheeting
Including various sorts of engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC |
Packages
Including plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. Coke bottles, peanut oil packages, Tetra Pak materials, vacuum bags, metal three-piece cans, plastic packages for cosmetic, soft tubes for toothpaste, jelly and yogurt cups |
| Extended Applications | Package Caps
Test seal performance of different package caps |
|---|
Solar Back-Sheets
Including solar back-sheets |
Plastic Pipes
Including various sorts of pipes, e.g. PPR |
Blister Packs
Test oxygen transmission rate of the whole blister packs |
Contact Lenses
Test oxygen transmission rate of contact lenses in usage situation |
Fuel Tanks of Cars
Plastic fuel tanks are widely used in cars for its light weight, buffering vibration and easy molding characters. But its fuel permeability is the most essential factor, this instrument can be used to test permeability of plastic fuel tanks |
Battery Plastic Shell
Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly dependent on its oxygen permeability. This instrument can be used to test oxgyen transmission rate of battery plastic shell |
Red Wine Bottles
Test oxygen transmission rate of red wine bottles |
Biodegradable Films
The oxygen transmission rate is an essential factor that affects biodegradable film properties and further development |
Soft Plastic Infusion Bottles
Oxygen is the main factor that leads injection to deterioration. It will be very important to lower oxygen content of infusion bottles |
Warm Paste Packages
Once touched with oxygen before usage, warm pastes will lose efficacy, they should be placed in vacuum packages. So it is necessary to test the oxygen transmission rate of warm pastes packages. |
