Thermal Endurance Tests on Silicone Rubber Specimens

摘要

Thermal endurance tests have been performed on a range of silicone rubber specimens at temperature above 300 exp 0 C. It is suggested that the rubber mix A2426, the compound from which Wylfa sealing rings are manufactured, will fail at temperatures above 300 exp 0 C within weeks. Hardness measurements show that this particular rubber performs in a similar manner to Walker's S.I.L./60. (Atomindex citation 09:354602)
