Keltan® 4460D
Amorphous ethylene-propylene rubber with medium DCPD (dicyclopentadiene) content and a medium Mooney viscosity. The broad molecular weight distribution of this product facilitates fast incorporation of carbon black. The highly branched structure of this product results in high levels of collapse resistance fast extrusion rates.
