BMC Composites have demonstrated more than 20 years of success in replacing die cast metals in engine sealing applications. BMC’s high strength, and ability to maintain the required properties under long term exposure to high temperatures and hot engine oil make it the perfect choice to reduce cost and weight in applications such as cylinder head covers, oil pans, engine front and rear covers.

The stiffness of the material allows for less ribbing and total material use compared to Polyamide thermoplastics. Its inherent creep resistance allows for larger bolt spans, improved multi-planar sealing and/or added safety factor in maintaining constant surface pressures on the sealing flange preventing oil leakage and potential engine fires.

BMC materials are specified as thermal barriers based on the high temperature properties to protect and/or insure the proper long term function for fuel pumps, tanks, injectors as well as other components located close to exhaust systems such as spare tires. With the proliferation of turbo chargers in more consumer transportation applications, engine covers are being employed to protect consumers from the hot turbo and/or EGR components located near the top of engines. These localized high temperatures exceed the capability of traditional engineering thermoplastic materials.
