Other ingredients include carbon black, oil and vulcanization systems; however the unique properties of the finished product are generated by the EPDM. The rubber compound is produced in large mixers, shaped into a profile or a molded article through an Extruder, then vulcanized by heating the shaped compound at 240-260 degrees Celsius in a Microwave Oven, resulting in the finished rubber product.

CompuDAS Control & Monitoring Systems are an ideal solution for updating, upgrading or replacing rubber vulcanizing Autoclave & Oven Control Systems. Vulcanization converts natural rubber or related polymers into more durable materials by adding sulfur or other curatives or accelerators. This modifies the rubber into a more stable form by creating cross link between the
Send InquiryEthylene Propylene Diene Monomer Rubber - an overview
A common rubber of this type is called ethylene propylene diene monomer rubber (EPDM), which has a small amount of a third monomer, a diene (two carbon–carbon double bonds in it). The diene monomer leaves a small amount of unsaturation in the polymer chain that can be used for sulfur cross-linking.
