High wear resistance grade S series
(ESTERAR / TPC)

Features

1. Excellent cold resistance, ozone resistance, and flow characteristics.
2. Excellent resistance to alkaline inorganic chemicals.
3. It can be lighter than cross-linked rubber.
4. It can be integrally molded with polar resins such as PC and ABS.(Excluding some grades)
5. Demonstrates wear resistance equivalent to or better than TPU.
6. There is no bleed and high sliding performance can be achieved.

※1 Softening temperature measurement method: Vicat softening temperature (at temperature rise rate of 50℃/hour and load of 2.5N)was determined with a needle inserted by 1mm.
※2 Shrinkage:A film gate sheet (126mm x 126mm x 2mm)was formed (at mold temperature of 40℃ and cooling period of 40 seconds).
※3 This is a grade that is made to order and sold.
