Abstract
An elastomeric seal (), such as a shaft seal for automotive vehicle applications, includes an elastomeric compound () chemically coupled to a metal sealing ring () and is formed without an oven post curing step. The elastomeric seal () provides exceptional physical properties, similar to those of elastomeric seals of the prior art formed with an oven post curing step. The elastomeric seal () has an elastic modulus of 6.0 MPa to 13.0 MPa and a tensile strength of 11.1 MPa to 14.8 MPa. The elastomeric compound () includes 52.0 to 68.0 wt. % fluoroelastomer, 20.0 to 35.0 wt. % calcium silicate, and 5.0 to 15.0 wt. % diatomite. The elastomeric compound () is fully cured and chemically coupled to the metal sealing ring () during the compression or injection molding step, and thus an oven post curing step is not required.
