Somos® 9420 White

Technical DataSheet | Supplied by DSM

Somos® 9420 White is a bright opaque white stereolithography photopolymer grade. Is an easy to use and fast to build grade. Exhibits flexibility, incredible memory retention, toughness and durability. Can be processed be 3D printing method. Produces accurate semi-flexible parts. Parts created from Somos® 9420 are comparable to polypropylene in mechanical properties and offer a good combination of flexibility and toughness. Used as prototypes where polypropylene will be the final production plastic. Recommended for manufacturing of bottle tops and fittings, designing and testing of snap-fits, electronic, automobile components as well as packaging.
