Impact-Resistant Series

Asahi Kasei's DELPET™︎ Impact-Resistant series is a methacrylic resin that uses special to technology to provide high-impact resistance while maintaining transparency and weather resistance.

Impact-Resistant Series

Achieves high levels of transparency and impact-resistance

Products and parts that may be subjected to impacts from moving parts or drops require impact resistance in addition to transparency. The Impact-Resistant series uses special technompactlogy to improve impact resistance while maintaining transparency and weather resistance, and can be used to match the strength required in the design.
