Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.
Labthink Shrinkage tester conforms to the multiple national and international standards:
RSY-R2 Film Free Shrink Tester is designed for the heat shrinkage test and size stability test of films, heat shrinkable pipelines, medical PVC sheets, back sheets and other materials in liquid medium at various temperatures.
Film Thermal Shrinkage Tester (Force Shrinkage Tester) is designed based on the ISO 14616 international standard. It is applicable to the precisely quantitative determination of the shrinking force, contracting force and shrinkage ratio for heatshrinkable plastic films during the thermal shrinkage process.
