Simrit will display its portfolio of silicone materials for the aerospace market at the 49th International Paris Air Show being conducted from 20 to 26 June, 2011 in Le Bourget, France.
The silicone material portfolio comprises fireproof, low density and high temperature silicone materials, which provide innovative solutions at reduced cost. According to Simrit’s Vice President of global sales aerospace, Vinay Nilkanth, silicone is suitable for aerospace applications as it can tolerate ultra low and high temperatures, standard aerospace fluids and environmental hazards.
Simrit's high-temperature, cured silicone rubber material is the latest advanced material designed for numerous aircraft uses, including grommets. The product is highly resistant to aerospace fluids and ideal for temperatures ranging between -55°C and 260°C. It has Die B tear strength of 45 ppi, tensile strength of 600 psi and up to 350% elongation.
The portfolio also includes proprietary silicone materials with low density such as the AMS 3303 and AMS 3302. They reduce weight by 15%-20% in aircraft structures over competitive materials. They have a specific gravity of <1, making them suitable for various sealing purposes, such as airframe seals, without compromising other physical characteristics.
Simrit offers a fireproof silicone material, which offers fire barrier solutions of up to 1094°C. at 15 minutes and eliminates the need for costly fabric layups, including aramid and ceramic. The seal can be produced without fabrics and with a thickness of 6.35 mm down to 0.81 mm by using a single layer of fiberglass fabric.
