Advanced compounds deliver superior performance

Utilising state-of-the-art facilities, unmatched material knowledge and a scientific approach, Pioneer Weston originates advanced elastomers and high performance engineered thermoplastics that unlock new performance possibilities.

Pioneer Weston Elastomer Materials

NBR

N-70-18

Developed specifically for rotary seals, N-70-18 Nitrile grade is formulated to ensure excellent compatibility with mineral and synthetic oils and greases. By reducing friction compared to general purpose Nitrile grades, the Pioneer Weston proprietary grade enhances service life and performance across an operating temperature range between -35°C and 110°C. At dedicated Rubix facilities, the Pioneer Weston technical team develop elastomeric and PTFE seal designs for field trials, supporting the expansion of our core range and the creation of new designs.

FKM

V-75-27

V-75-27 FKM is a black A-type fluorocarbon that features the inherent oil and grease compatibility of NBR, but with increased suitability for higher speed, higher temperature applications. FKM has an operating temperature range of -20°C to 200°C.

HNBR

H-80-40

H-80-40 HNBR offers an improved abrasion resistance and operating temperature range compared to NBR, reliably performing between -40°C and 180°C. HNBR provides a long service life in extreme environmental conditions, which makes the material popular in off-highway applications.

Several factors affect material selection for a dynamic rotary seal. To help narrow your selection, it’s always best to talk to one of our experts.
