Flexibility with excellent impact strength 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 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 printed parts.
The distinguishing mark in the name of the filament, 85A, refers to the material’s hardness on the Shore scale and classifies Spectrum S-Flex 85A among hard elastomers.
This property, in terms of the 3D printing process, reduces the risk of filament deformation in the feeding system leading the material to the print head.
This allows 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, sharp edge guards), 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 tear and tensile resistance - low shrinkage - resistance to many common industrial oils and chemicals - reduced stringing when the printer is idle
Applications:
- production of seals with high chemical resistance - production of items used as energy absorbers - functional parts - all kinds of bumpers, vibration dampers - protective housings - snap-fit parts - sleeves - hinges - bumpers and flexible spacers - sealing components with increased stiffness - spring damping elements for use in mechanical engineering and modeling - flexible belts with high strength - covers and housings for various devices
Filament specifications:
- filament diameter: 1.75mm / 2.85mm - extrusion temperature: 200–230"C - bed temperature: 50–70"C - print speed: 20–70mm/s
