WRS-01 thermal shrinkage tester, also known as thermal shrinkage rate tester, thermal shrinkage tester, etc., is suitable for testing the thermal shrinkage performance of materials. It is suitable for testing the thermal shrinkage performance of various films in liquid media at various temperatures, such as PE thermal shrinkage film for integrated packaging of alcoholic beverages, cans, mineral water, and various beverages, as well as PVC, POF, OPS, PET and other materials with thermal shrinkage performance suitable for various packaging, flexible packaging composite film, PVC polyvinyl chloride hard sheet, solar cell backboard and other materials.

test method

The instrument accurately controls the temperature of the hot oil in the heating tank. The sample is cut to a certain size and placed in the heating tank for a certain period of time. After reaching the specified time, the sample is taken out and cooled to room temperature. The size of the sample is measured and the thermal shrinkage rate is calculated.
