Flexa W
Flexa W: Polyproplyene-Like
Flexa W is a flexible plastic ideal for snap fit assemblies, vacuum casting master patterns, and for durable prototypes where it recreates the effect of molded polypropylene (PP). It 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.
Advantages
Flexible, High level of elongation, Durable, Very bright white, Easy to process and finish
Application
Snap-fit parts and casings, Any durable prototype.
