SPECTRUM Filament TPU S-Flex 98A black 0.5kg 1.75mm, 36.50 CHF

Spectrum TPU S-Flex 98A 1.75mm 0.5kg Deep Black

Flexibility with very good impact strength and thermal insulation

Spectrum S-Flex 98A is a filament based on a thermoplastic polyether polyurethane. In the area of additive manufacturing, S-Flex 98A is a material characterized by a relatively easy and failure-free 3D printing process. An additional advantage that allows obtaining a perfect printout is very good adhesion of the first layer of the printed part to the working space, regardless of whether it is made of glass, steel, plastic or other material.
Low processing shrinkage and high flexibility significantly reduce the risk of the so-called curling up of the edges of manufactured parts. The distinguishing feature in the filament name 98A – relates to the hardness of the material on the Shore scale and classifies Spectrum S-Flex 98A in the category of hard elastomers. This property from the point of view of the 3D printing process reduces the risk of filament deformation in the insertion system leading the the material to the printing head. This enables a slightly faster printing compared to other, more compliant elastomers.
Parts made of Spectrum S-Flex 98A are characterized by very high resistance to hydrolysis (a kind 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 3D print parts that protect surfaces exposed to impact (bumpers, sharp edge guards), sealing and protective elements with high chemical resistance, as well as thermal insulators.

The filament is delivered vacuum sealed & reeled on a transparent spool.

Applications

manufacturing of seals with a high chemical resistance
production of items, which has to be used as energy adsorbents
functional parts
all kinds of bumpers, vibration dampers
guides
protective cases
snap-fit parts
sleeves
hinges

Storage
Cool and dry (15-25°C) and away from UV light. This enhances the shelf life significantly.

Each desktop 3D printer has its own unique characteristics, you might need to tweak around with your temperature settings a bit to obtain the best results. To obtain optimal results for your prints you need to take into account variables like your 3D printer’s nozzle diameter, your printing speed settings, and layer height.
