The Most Revolutionary Innovation In The Field Of Unbreakable Polymer

During the ’90s Simula Technologies develoed NXT for military purpose to satisfy a specific need: a transparent, lightweight and bullet proof material superior to Polycarbonate.

In 1996 Simula Technologies formed a strategic alliance with INTERCAST to futher develop the technology and optimize the material for optical uses.
