EPDM is a M Class Rubber
EPDM has good abrasion and tear resistance to a variety of acids and bases. It is susceptible to attack by oils and is not recommended for applications involving petroleum oils, strong acids or strong bases. It has exceptionally good weather aging and ozone resistance. It is fairly good with ketones and alcohols and has an excellent temperature range. Because it has a negligible absorption rate, it is not susceptible to swelling.
It is the most economical of the elastomers.
EDPM meets CSA standard B137.0-1973 for toxicity.
