Due to its low level of crystallinity, Ensinger's polycarbonate, marketed as TECANAT natural, has a high level of transparency. The unmodified PC is characterized by high strength, rigidity and hardness, as well as good impact strength. However, as is the case with all amorphous thermoplastics, lower chemical resistance may be a limiting factor in the material selection process.
