| Popis: | Elastomeric sealants employed in thermal solar collectors are subjected to extremely harsh conditions. In order to function properly for long periods of time, they must exhibit good resistance to environmental factors such as high and low temperature extremes, oxygen, ozone, water, and ultraviolet radiation. Several types of candidate elastomers consisting of fluorocarbon, silicone, acrylic, ethylene-acrylic, ethylene-propylene terpolymer, and butyl and chlorosulfonated polyethylene were subjected to extensive testing. Results are reported on outgassing characteristics during thermal aging and on retention of such physical properties as compression set, elongation, and tensile strength. Relative hydrolytic stabilities of these materials are also discussed. 1 ref. |
