Keltan 6950C is suitable for automotive sponge applications, dense profiles, building/construction, insulation sponge, industrial/machinery, rollers, hoses, insulation sponge, tires, sidewalls and wiper blades.
KELTAN 6950C has a shelf life of 36 months.
Amorphous ethylene-propylene rubber with high ENB (ethylidene norbornene) content and a medium Mooney viscosity.
The very low ethylene content ensures excellent low temperature properties.
The high ENB content contribute to an ultra fast curing of the compound.
Keltan 6950C is very suitable for automotive sponge applications, dense profiles and wiper blades.
Keltan 6950C has the broadest portfolio of premium EPDM grades in the world.
Keltan 6950C's grades are used in a wide variety of everyday products, ranging from wire & cable to household appliances, tire & tube, roofing & geo-membranes, and other miscellaneous rubber articles.
Keltan 6950C products are globally the choice of automotive component designers, replacing much less heat-stable natural rubber.
Keltan 6950C is primarily used in the automotive industry for automotive body sealing, radiator hoses, brake parts and belts or engine mounts, including windshield wipers.
They exhibit very low density and are highly resistant against oxygen, ozone, heat and irradiation.
Cross-linked EPDM rubbers also have good mechanical and elastic properties.
Keltan 6950C grades have exactly the same specifications as their conventional counterparts, they are 'drop-in' equivalents with one important difference: up to 70% of the content is bio-based.
Thus they offer an environmentally friendly alternative for any type of EPDM application.
Today these new bio-based EPDM grades are commercially applied in applications, such as low-weight, micro porous automotive solid seals, recyclable TPV's, the official soccer World Cup match ball, flooring and window seals.
