Metsa Fibre s Joutseno mill in Finland started up the world s largest single polysulfide
Among the selected elastomers are natural rubber, fluoroelastomer, silicone, fluorosilicone, urethane, nitrile, butyl, EPDM, polybutadiene and polysulfide
Among the elastomers listed are natural robber, synthetics in common usage such as EPDM, silicone, urethane and polysulfide
, and some of today's more exotic synthetic rubbers, such as fluoroelastomer and fluorosilicone.
Hydrin epichlorohydrin elastomers are said to offer mechanical properties similar to those of natural rubber, along with many of the desirable properties of nitrile, polychloroprene, polysulfide
and polyacrylic elastomers.
NXT LowV silane and NXT Ultra-LowV silane coupling agents are said to help decrease ethanol emissions by up to 90% compared to polysulfide
The TESPT has a polysulfide
chain with S ranking of about 3.
