Product Information
Tecknit Allycarbonate shielded windows are manufactured by casting a woven EMI shielding mesh into a glass like substrate.

The window offers a lightweight, cost-effective alternative to traditional glass laminates, and is a more flexible solution to machine, making it more suited to meet the changing design demands that are part of modern electronics.

Each window is machined using a 3 axis CNC machining centre, and can be supplied with or without conductive gasket.

Allylcarbonate is scratch resistant, and resists most acids and solvents, making it ideal for both military and harsh industrial applications.
