ELGIN, Ill.—Simrit, a global supplier of precision-manufactured products for the aerospace industry, has developed a proprietary, low-density silicone material that was successfully used in nacelle systems.
Nacelle systems—housings that contain aircraft engines—are critical to the overall efficiency of aircraft, as well as a key area for weight savings and fuel economy improvements.
Simrit said it developed its cost-effective AMS 3302 and AMS 3303 silicone material to provide a 15 to 20 percent weight savings over similar materials.
With a specific gravity of less than one, it has the same physical properties of traditional silicone materials, but at a reduced weight, the company said.
Simrit said the material can be used for numerous aerospace sealing applications, including airframe seals and pressure and environmental sealing applications of nacelle systems. The material withstands extreme low and high temperatures, is resistant to common aircraft fluids and can be combined into fireproof constructions, according to the company.
