due to radiation from beam loss. In a search for radiation resistant seals suitable for vacuum systems, nine elastomer samples were obtained from Minnesota Rubber Company and irradiated with gamma rays. Materials Tested The samples tested were: Compound W 559N EPDM (Ethylene Propylene Diene) 559EQ 366T 514AD 71417
In fact, EPDM compounds have good results of compression set after radiation exposure and Silicone rubber does not have good results. It had been predicted that breakage and crosslinking of elastomer chemical structure caused by radiation would have been more serious on Silicone rubber.
Oct 31, 2016· EPDM rubber is classified as radiation-resistant, because EPDM structure includes in its principal chain totally saturated bonds, and consequently is able to absorb more energy without cracking polymeric chain. The purpose of this work was studying radiation influence on rubbers compounds used in wires and electrical cables installed in Nuclear ...

EPDM rubber (ethylene propylene diene monomer rubber), is a type of synthetic rubber, which can be used in a wide range of applications.This is an M-Class rubber where the 'M' in M-Class refers to its classification in ASTM standard D-1418; the M class comprises elastomers having a saturated chain of the polyethylene type (the M deriving from the more correct term polymethylene).
Flame and radiation resistant modification of ethylene-propylene-diene rubber with brominated acenaphthylenes ... The biggest problem is that the radiation resistance of the base rubber becomes lower when it is mixed with conventional flame retardants This paper outlines the results of small scale performance tests of new flame retardants which ...
Self-adhesive and root-resistant EPDM membrane. RESITRIX ® SK W Full Bond is a fully self-adhesive, hot air-weldable and root-resistant EPDM waterproofing membrane with FLL test certificate and approval according to DIN EN 13948.
