Elastomers<br />
The following profiles are offered as a general guide and indication of the suitability of various elastomers in use<br />
today for service with these chemicals and fluids. The ratings are based, for the most part, on published<br />
literature of various elastomer suppliers and rubber manufacturers, but, in some case, they are the opionion of<br />
experienced compounders. We cannot guarantee their accuracy nor assume responsibility for use thereof.<br />
