Bionic Face Shield

Bionic Face Shield

Description

WeeTect bionic face shield (WBFS) is a custom injection molding face shield with bionic design which can realize the design from customer. It has an outstanding 180 degree field of vision with no distortion and is complaint with EN166 and ANSI Z87.1 2003 which can applies to grinding face shield, chemical face shield and other mechanical work protection.

WeeTect bionic face shield (WBFS) has excellent optics combined with increased visibility. It boasts the following qualities: fog-free, scratch resistant, optical clarity (class 1), high impact resistant (resists a 6 mm, 0.86 g ball at 120 m/s).

Having a sustainable performance increases the longevity of the product and reduces significant product manufacturing cost, WeeTect bionic face shield (WBFS) is popularly used in head protection. It provides great protection against flying debris from cutting, grinding, woodworking, lawn care and hazards from mechanical work, do it yourself projects, hobbies, liquid chemical splash; any task where you need to protect your eyes and face.
