Metallocene EPDM is suited to TPVs.

Metallocene EPDM is entering new applications such as TPV compounding, thanks to new gas-phase technology. DuPont Dow Elastomers, Wilmington, Del., has introduced new Nordel MG gas-phase mEPDM grades (47130, 46140 and 47100) that have very high Mooney viscosity (>100) and do not need oil extenders. High-Mooney grades are said to be well suited to formulation of polypropylene-based thermoplastic vulcanizates (TPVs). Their granular form eliminates an entire step in TPV compounding because no bale grinding is needed. Significantly higher throughput in TPV continuous compounding equipment has also been demonstrated. Tel: (800) 853-5515, www.dupont-dow.com
