產品特點：
Product features:
指試樣的初始厚度與在規定時間、規定溫度下壓縮后，經過規定恢復時間的試樣zui終厚度差異。差異的大小與初始厚度有關。
The initial thickness and in the specified time, the prescribed temperature compressed specimen, specimen thickness difference after the prescribed final recovery time. The size difference is related to the initial thickness.
主要用途：
Main uses:
用夾具及定位塊將海綿壓陷至原始厚度的50%、75%、90%，放置在規定溫度的恒溫箱內，待至22小時、72小時之后從中取出壓縮器，將試樣從壓縮器中取出放置30min后，測量厚度，計算其變形量。
With a clamp and a positioning block will sponge indentation to the original thickness of 50%, 75%, 90%, were placed at a prescribed temperature in the oven temperature, after up to 22 hours, 72 hours out of the compressor, the sample from the compressor out after insertion of 30min, thickness measurement, calculation of the deformation.
