Abstract
Предложенный термостойкий уплотнительный материал 130а и 130b согласно изобретению включает в себя 100 мас.ч. тройного фторэластомера, 1-30 мас.ч. углеродных волокон, выращенных из паровой фазы, имеющих средний диаметр более 30 и 200 нм или менее, и углеродную сажу, имеющую средний диаметр частиц 25-500 нм. Термостойкий уплотнительный материал 130а и 130b содержит углеродные волокна, выращенные из паровой фазы, и углеродную сажу в суммарном количестве 20-40 мас.ч. Термостойкий уплотнительный материал 130а и 130b имеет усадку при сжатии, составляющую от 0 до 15%, когда его подвергают испытанию на усадку при сжатии со степенью сжатия 25% при температуре 200°С в течение 70 ч, и динамический модуль упругости при 200°С (Е'/200°С), составляющий от 30 до 100 МПа.
