That is, TPU generally has poor friction coefficient stability, and conversely, if modified to improve the friction coefficient stability, wear resistance becomes poor, resulting in poor take-up and transportability of paper sheets. It is.

重量部に限定したのは次の理由のためである。In the present invention, TPU / TPS =
For 100 parts by weight of the blend rubber of 98/2 to 30/70, 0.1 to 100 parts by weight of PPE and 1 to 200 parts by weight of oil
The reason for limiting to parts by weight is as follows.

なわれる為である。First, as the base rubber, TPU / TPS =
The blend rubber of 98/2 to 30/70 is made of TP
If the U content is 2% by weight or less, the compression set is large and the practicality is poor. On the other hand, if it exceeds 70% by weight, the wear resistance is impaired.

The reason why PPE was limited to 0.1 to 100 parts by weight with respect to 100 parts by weight of the blend rubber of No. 70 is that if it is 0.1 part by weight or less, the compression set is large and the practicality is poor.
If the amount exceeds 0 parts by weight, the coefficient of friction becomes low.

The reason why the amount is limited to 00 parts by weight is that if it is less than 1 part by weight, the compression set is large and practicality is poor, and if it exceeds 100 parts by weight, the friction coefficient becomes low.
