Simrit supplies emergency door seal to China's first commercial aircraft

Simrit – the industrial sealing products division of Freudenberg-NOK Sealing Technologies – is supplying a customized silicone seal for the emergency door application in China's first commercial aircraft. Specifically designed for the precise requirements of the emergency door application, the seal offers low abrasion and reduced friction characteristics to meet the demanding needs of the global aerospace industry. These requirements were critical to the success of the seal, as they result in increased durability when opening and closing of an emergency door is necessary.

"The technology resources at our Tillsonburg, Ontario, Canada facility and Malaysia Technology Center did an excellent job in designing and validating the customer's proposed design," said Vinay Nilkanth, vice president global sales aerospace, Simrit. "Not only did this global collaboration develop a solution that met the customer's final requirement, but the seal design also outperformed the competition's seal."

The single-piece seal met the customer's technical requirements, as well as general door requirements, which included ease of opening and accessibility during service and maintenance. Additionally, the seal provides low temperature capability and successfully satisfied the customer's load deflection and closure force conditions.

The Tillsonburg plant – Freudenberg-NOK Sealing Technologies' oldest manufacturing facility – designs and manufactures aerodynamic seals and sealing products, including engine seals, thrust reverse seals and door and window seals, for commercial aircrafts and jet engines. The facility was named a United Technologies Corp. Supplier Gold Award winner for three consecutive years (2009 - 2011). Opened in 2005, the Malaysia Technology Center is an engineering development facility that provides vital technical around the clock support to improve turnaround times both locally and globally.
