In the first part of this blog series we compared the flexibility of acrylic and polycarbonate. We showed that 0.47″ Polycarbonate is 20-25% more flexible than the same thickness Acrylic under simulated hockey player impact conditions. This increased flexibility could potentially lead to a reduced number of player concussions and reduce concussion severity. In this […]
