Kettlitz Chemie Mediaplast NB-7

Kettlitz-Mediaplast NB-7 is a special diisononyl dicarboxylic acid ester which can replace existing phthalate plasticizers in compounds based on polar rubbers like NBR, HNBR, CR, ACM, VAMAC etc. Mediaplast NB-7 shows minor volatility at an extremely low setting point. Therefore this plasticizer is suitable to produce rubber articles with high heat resistance and excellent low temperature propertiesas well.

Functions: Plasticizer

Chemical Family: Esters

Compatible Polymers & Resins: Chloroprene Rubber (CR), Nitrile Butadiene Rubber (NBR)

End Uses: Footwear, Housewares, Sporting Goods, Tires, Tubing

Features

Within the rubber compounds mentioned above, Mediaplast NB-7 reacts similar to the known phthalate plasticizers. However, there is no duty of declaration according to the raw material lists of some automotive manufacturers (current regulations, January 2005). Compared to other possible alternatives like DOS and DOA, Mediaplast NB-7 shows a considerably higher compatibility within the polymers mentioned above. Depending on the ACN and filler content, usually more than 30 phr of Mediaplast NB-7 can be incorporated into carbon black filled NBR compounds
