Abstract
A conductive rubber composite coating can be provided from both an aqueous or non-aqueous formulation which includes a mixture, preferably a homogenous mixture, of a nitrile butadiene rubber (NBR), a polyester and at least one conductive filler. In some embodiments, and after coating and vulcanization the formulation to a substrate, a conductive rubber coated article of manufacture (e.g., rubber coated material gasket) is provided that has conductivity and electromagnetic interference shielding suitable for use in EV applications.
Claims20
A formulation comprising:
- a mixture of from about 20 weight percent to about 90 weight percent of nitrile butadiene rubber, from about 5 weight percent to about 50 weight percent of a polyester, and from about 5 weight percent to about 40 weight percent of at least one conductive filler.
A conductive rubber composite coating comprising:
- an elastomeric polymer blend of a nitrile butadiene rubber and a polyester, wherein the elastomeric polymer blend has at least one conductive filler contained therein, and a conductivity of about 10E−4 Siemens/centimeter or greater.
