® BTC has been authorized as exclusive agent of this material in China market. 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. NXT’s Oringin ®
