Spectrum S-Flex 85A Polar White, 1.75mm / 250g

Flexibility with very good impact strength and thermal insulation

Spectrum S-Flex 85A is a thermoplastic polyether polyurethane-based flexible filament that features a relatively simple and trouble-free 3D printing process.

One advantage is the very good adhesion of the first print layer to the work surface, regardless of whether it is on glass, steel, plastic or other material. Low shrinkage and high flexibility significantly reduce the risk of so-called curling of the edges of printed parts.

The 85A shore hardness places Spectrum S-Flex 85A in the category of hard elastomers. This property reduces the risk of filament deformation and allows for a slightly faster print compared to other, more compliant elastomers.

Spectrum S-Flex 85A parts are characterised 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.
