New EPDM grade can replace NR in auto, industrial applications

German specialty chemicals company, Lanxess introduces its newly commercialised, ultra-high molecular weight EPDM grade Keltan 9565Q, at the 2014 International Rubber Expo held from 14-16 October in Nashville, Tennessee, US.

At the show, the new EPDM grade is offered as substitute for natural rubber (NR) in dynamic applications, says Lanxess.

Increasingly sophisticated automotive and industrial applications require improved high temperature performance, which NR, known to degrade quickly at elevated temperatures, cannot provide.

Keltan 9565Q with its tailored molecular structure matches the strength and resilience of NR, while also maintaining these superior properties after high temperature exposure, according to Niels van der Aar, Head of Technical Service & Application Development for Lanxess Keltan Elastomers business.

He adds that the high temperature resistance also enables Keltan 9565Q to be processed at elevated temperatures, thus improving moulding productivity and reducing costs.

The saturated polymer backbone gives EPDM its superior ozone, UV, and heat resistance properties. Keltan 9565Q also offers the strength, fatigue resistance, and resilience achieved by NR at lower temperatures.

The Keltan-brand EPDM is used for the manufacture of door sealants, hoses, belts or anti-vibration parts. The product is also used in plastic modification, wire and cable, construction and oil additives.
