Flexa W

Material Overview

Flexa W is not only a highly flexible material, it also has good strength and is resistant to high humidity. By having a high degree of elongation but remaining robust and stable, this plastic is perfect for various forms of clip or snap fit products. It simulates PP well and is used widely in consumer electronics, as well as the automotive industry and dentistry. The bright white color is extremely attractive and eye-catching, which really helps prototypes stand out.
