Film Free Shrink Tester FST-01
Shrinkage Films Background
A film or sheet is formed by heating a polymer to a molten state. The process is most often extruded or calendared. In the process, the molten film is pulled under tension, thus caused a stretching in the machine direction. Then the film is cooled to form into a given thickness, width etc. Some undesirable stressed are locked in. When a plastic film or sheet is reheated, it can change in linear dimension. This is typically referred to as shrinkage.
Shrinkage is a crucial indicator of the plastic’s manufacturing process, serving purposes such as quality and process control. The FST-01 Film Free Shrink Tester is designed to assess the unrestrained linear thermal shrinkage of plastic film and sheeting at specified temperatures in a fluid medium.
Film Free Shrink Tester Application
The FST-01 Film Free Shrink Tester is specifically designed to determine the degree of unrestrained linear thermal shrinkage in plastic films and sheeting within a fluid medium. This makes it an essential tool for industries such as packaging, food, medicine, and beverage, offering precise insights into the characteristics of materials used in diverse applications.
Film Free Shrink Tester Test Process
- A temperature probe is located to fluid heating area.
- Mount the test specimen on the free shrink holder and place in the liquid bath when desired temperature is reached.
- When time is up, the alarm beeps.
- Remove test specimen and press Stop button to finish the test.
- Treat the specimen at ambient environment and measure the shrinkage.
