Principle
The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.

FUJI developed the first infrared gas analyzer in Japan to use mass-flow sensors. Since then, we have supplied customers with various types of gas analyzers to support environmental preservation and control efforts. These efforts include measurements of atmospheric pollution and detection of low density of SOx and NOx, generated by incinerating facilities and boilers. FUJI's gas analyzers are widely used to monitor the atmosphere to help maintain a cleaner natural environment.

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1
Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.
GBPI Film Shrinkage tester conforms to the multiple national and international standards:
ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of
shrinkage stress and contraction stress
DIN 53369 - Testing of plastic films determination of the shrinking stress
Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on.
Principle
This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23 to cool down.
The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film.
