Spectrum Filament S-Flex 85A 250g, bloody red

Flexibility with very good impact toughness 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 a material characterized by a relatively easy and trouble-free 3D printing process. Another advantage that enables achieving a perfect print is the very good adhesion of the first layer of the printed part to the build platform, regardless of whether it is made of glass, steel, plastic, or another material. Low processing shrinkage and high flexibility significantly reduce the risk of so-called edge warping of manufactured parts. The distinguishing feature in the filament name 85A refers to the material hardness on the Shore scale and places Spectrum S-Flex 85A in the category of hard elastomers. This property reduces the risk of filament deformation in the feed system leading the material to the print head during the 3D printing process. This allows for slightly faster printing compared to other, more flexible elastomers.

Parts made from Spectrum S-Flex 85A are characterized by very high resistance to hydrolysis (a type of degradation caused by the presence of water), good recyclability, and very good resistance to dynamic forces. Thanks to these properties, it is possible to print 3D parts that protect surfaces exposed to impact (bumpers, edge protectors), sealing and protective elements with high chemical resistance, and also thermal insulators.

Key features:
High resistance to hydrolysis. Up to 650% elongation at break. Shore A hardness 85. High resistance to tearing and tension. Low shrinkage. Resistance to many common industrial oils and chemicals. Reduced chain breakage during printer inactivity.

Applications:
Production of seals with high chemical resistance. Production of items that must be used as energy absorbers. Functional parts. All kinds of bumpers, vibration dampers. Protective housings. Snap-fit parts. Sleeves. Hinges. Bumpers and flexible spacers. Sealing parts with increased stiffness. Spring damping elements for use in machinery manufacturing and modeling. Flexible belts with high strength. Covers and housings for various devices.

Filament specifications:
Filament diameter: 1.75 mm / 2.85 mm. Extrusion temperature: 200–230 "C. Bed temperature: 50–70 "C. Print speed: 20–70 mm/s.
