▶ Comparison Test of Appearance of Compressed 50% High-temperature Oil Separation
(1) Attach a layer of filter paper to the top and bottom of the conventional WT5935C-500-85 and WT5935C-500-A90 (low oil separation) thermal pads, and use the filter paper to evenly adhere them to both sides of the product. Then, use a fixture to clamp and compress the sample to about 50% and maintain it;
(2) Place the fixture with the sample in a constant temperature drying oven at 120 ℃ and maintain it for 48 hours;
(3) After 48 hours, take it out and leave it at room temperature for 30 minutes. Then, remove the filter paper and observe the oil print under the measuring display mirror.
