It has been found that this material can keep rubber elasticity even at low temperatures blow -70℃, though it is somewhat inferior to the other two materials as to strengths such as stress-at-break and tear; and hence, it is considered as quite worthy of a practical test under equipped for a snow vehicle in the Antarctic area.}, pages = {398--409}, title = {南極大型雪上車 (SM100S) の開発 IV. ゴム履帯の低温特性}, volume = {36}, year = {1992}, yomi = {マエカワ, エツジ and テラヤマ, ヨシヒデ} }
