Remark
Because TF is made from cellulose, it tends to absorb moisture, and depending on circumstances, it might contain 7-10% moisture. When assembling cell with TF, sufficient drying is required. Recommended drying condition is in the range of 100-160 deg C within 24 hours by vacuum drying. After drying procedure, please handle the products under the low dew point environment. Recommended dew point is less than -60 deg C. In the drying procedure, the products may shrink about 1% length-wise and width-wise, so please design your product after taking this shrinkage into consideration.
