Spectrum 3D filament, S-Flex 85A, 1,75mm, 250g, 80568, lime green

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 ensures a perfect print is the excellent adhesion of the first printed layer to the build surface – 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 designation "85A" refers to the Shore hardness of the material and classifies Spectrum S-Flex 85A as a hard elastomer. This property reduces the risk of filament deformation in the feed system leading to the print head, allowing slightly faster printing compared to softer elastomers.
Parts made from Spectrum S-Flex 85A exhibit very high resistance to hydrolysis (a type of degradation caused by water), good recyclability, and excellent resistance to dynamic forces. These properties allow for the 3D printing of parts that protect surfaces from impact (such as bumpers, edge protectors), sealing and protective elements with high chemical resistance, and thermal insulators.

Key properties:

high resistance to hydrolysis

up to 650% elongation at break
