    New Delhi - Safety systems manufacturer Simula Inc. has filed a patent application for a process for preparing a polyurethane material, the US-based company said in a 28 July statement.

    Simula supplies human safety and survival systems for all branches of the US military, major aerospace and defence contractors, as well as consumer markets.

    The inventor of the PU process is Edwin Slagel, Simula said. The company filed the patent application on 30 Oct 1998, with patent application number 3206/DEL/1998 A.

    According to the controller general of patents, designs & trade marks, "The present invention is an optically clear, high hardness, impact resistant polyurethane which provides exceptionally high heat distortion temperatures and excellent chemical resistance."

    The invention can be used in transparency applications that require excellent impact resistance with high heat-distortion temperatures, such as riot shields, aircraft canopies, face masks, protective eyewear, and transparent armour, according to the application.
