ActiveRubber—Determination of 5-ethylidenenorbornene (ENB) or dicyclopentadiene (DCPD) in ethylene-propylene-diene (EPDM) terpolymers
橡胶 乙烯-丙烯-二烯烃（EPDM）三元共聚物中5-乙叉降冰片烯（ENB）或双环戊二烯（DCPD）的测定
Application Summary AI generated
This standard specifies a method for determining the content of ENB or DCPD, the third monomers used in EPDM rubber, to verify polymer composition and quality. It is applied in the rubber and plastics industry for raw material inspection, quality control during EPDM production, and acceptance testing of commercial EPDM grades. The method is relevant for manufacturers, compounders, and testing laboratories to ensure consistent curing behavior and end-product performance.
