FST**1 Film Free Shrink TesterÂ
Background
Plastic films and sheets are typically made by melting polymer
material and then shaping it through processes like extrusion or
calendaring. During this production, the material is stretched in
the machine direction, and as it cools, some internal stresses
remain. When reheated, these stresses can cause the material to
shrink, altering its dimensions.Â
This shrinkage is crucial for quality and process control in
plastic manufacturing.Â
It helps assess process consistency, adjust production parameters,
and understand material characteristics. Industries like packaging
rely on shrinkage data to ensure precise fit after heat
exposure.Â
In essence, shrinkage is a key factor in maintaining product
quality and process efficiency in plastic film and sheet
production.
Application
The FST**1 Film Free Shrink Tester is used to measure the
unrestrained linear thermal shrinkage of plastic film and sheets at
specified temperatures in a fluid medium. This device helps assess
how much these materials will shrink when exposed to heat in
real-world applications.
Test Process
1. Temperature Setup and Stabilization: Set the temperature on PID
controller and the fluid is heated to a preset temperature and
temperature is stabilized.Â
2. Specimen Preparation and Submersion: Mount the test specimen
into the free shrink holder. Submerge them together into the liquid
bath.
3. Time Monitoring and Completion: The timer starts to count down
and when the test time is reached, an alarm will beep, signaling
the end of the test.
4. Test Conclusion: Carefully remove the test specimen from the
liquid bath. Press the Stop on the tester to mark the
conclusion of the test.
5. Shrinkage Measurement and Assessment: Treat test specimen in
ambient environment and Measure the linear shrinkage of the
specimen.
Calculation
To calculate the unrestrained linear shrinkage percentage using the
given formula:Â
Unrestrained Linear Shrinkage (%) = [(Lo - Lf) / Lo] x **0
Where:
Lo = Initial length (**0 mm)
Lf = Length of the side after shrinking
Technical FeaturesÂ
1. Precise P.I.D. temperature control
2. High-precision timer
3. Alarm capability
4. Consistent fluid medium heating
5. Inclusion of a standard square metal clamp and a free shrink
holder
6. Equipped with an oil bath cover
