... is used with Saret SR-522 coagent (Sartomer, Exton, PA/USA), a diacrylate ester, for applications such as radiator hoses. Similar trends can be seen with other manufacturers’ products, for example Nordel 1040 (HD grade from DPPE). DPPE has added to its Nordel MG range of metallocene gas phase products. These grades have ethylene contents from 50 to 80% and Mooney viscosities from 60 to 200 and complement the IP grades and conventional EPDM grades. Nordel MG delivers a 5 to 10% increased mixer f...

... a new oil-extended EPDM with a well-balanced microstructure, which is claimed to permit high heating rates and excellent extrudability, even for extremely difficult profiles. The Nordel IP grades unveiled by DuPont Dow Elastomers (DDE) at K’98 were complemented at K’01 with Nordel MG metallocene gas-phase grades, which are produced by the process originally presented by Union Carbide [3] in 1995. With ethylene contents of 50 to 80% and Mooney viscosities from 60 to 200, they provide a complemen...

...lass-fibre-reinforced polyarylamide PAMXD6 GF50 (grade: IXEF1022; Fig.3) [4]. The tyre manufacturer Cheng Shin Rubber Industry Co. Ltd., Taiwan, makes bicycle inner tubes and tyres from a hydrocarbon rubber (grade: Nordel-IP) from DuPont Dow Elastomers. The tyre treads and flanks are made of a Nordel MG blended with natural rubber (NR) and styrene-butadiene rubber (SBR). The tyres and inner tubes now improve the severe demands that mountain bike races, such as the “Maxxis International Cup” make...

... With the introduction of single-site catalysts with fixed geometry (CGC), a new class of polyolefin elastomers was born [1, 2, 3]. Following the success of Engage ethylene-octene copolymers, and the completion of DuPont Dow Elastomer's range of Nordel IP EPDM polymers, further ethylene copolymers based on metallocene technology are now poised for market launch. Nordel IP is the first mass-produced EPDM based on this catalyst. For the first time it is possible to selectively control the mole...
