Vulcanizates that have not been post-cured can be used in numerous applications as post-curing has only little effect on mechanical properties.  To obtain optimum compression set values it is advisable to post cure for 4 h at 200 °C.


The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
