Flexibility with very good impact resistance and thermal insulation. Spectrum S-Flex 85A™ is a filament based on thermoplastic polyether polyurethane. In the field of additive manufacturing, S-Flex 85A™ is characterized by a relatively simple and trouble-free 3D printing process. An additional advantage is the excellent adhesion of the first layer of the printed part to the build plate, regardless of whether it is made of glass, steel, plastic, or another material. Low processing shrinkage and very high flexibility reduce the risk of warping edges in the produced parts. The filament name – 85A – refers to the hardness of the material on the Shore scale. The risk of deformation of the filament in the area of the filament feed to the print heads has been reduced, allowing for slightly faster printing compared to other, more vulnerable elastomers. The additively manufactured parts made from S-Flex 85A™ exhibit very high hydrolysis resistance, good recyclability, and excellent resistance to dynamic forces. Thanks to these properties, it is possible to print 3D parts for the protection of impact-prone surfaces, sealing and protective elements with high chemical resistance, as well as thermal insulators. Application areas include bushings, vibration dampers, protective covers, snap-fit parts, edge protection against impacts, bumpers, and flexible spacers, sealing parts with increased rigidity, spring-damping elements for use in machinery and model building, flexible bands with high strength, covers, and housings for various devices.
