Spectrum S-Flex 85A 1.75mm 0.50kg filament

Flexibility with excellent impact resistance and thermal insulation

Spectrum S-Flex 85A is a filament based on a thermoplastic polyether polyurethane. In the context of additive manufacturing, S-Flex 85A is a material characterized by a relatively simple and error-free 3D printing process. An additional advantage that allows for a perfect print is the excellent adhesion of the first layer of the printed part to the workspace, regardless of whether it is made of glass, steel, plastic or other material.

Low processing shrinkage and high flexibility significantly reduce the risk of so-called edge curling of the produced parts. The distinguishing feature in the name of the filament 85A is related to the hardness of the material on the Shore scale and places Spectrum S-Flex 85A in the category of hard elastomers. This property from the perspective of the 3D printing process reduces the risk of deformation of the filament in the feed system that leads the material to the print head. This allows for slightly faster printing compared to other, more compliant elastomers.

Parts made of 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 excellent resistance to dynamic forces. Thanks to these properties, it is possible to 3D print parts that protect surfaces exposed to impacts (bumpers, sharp edge protectors), sealing and protection elements with high chemical resistance, as well as thermal insulators.

Main features:

• high resistance to hydrolysis
• up to 650% elongation at break
• Shore-A hardness of 85
• high tensile and tear resistance
• low shrinkage
• resistance to many common industrial oils and chemicals
• Reduced string formation while the printer is idle

Applications:

• production of gaskets with high chemical resistance
• production of articles which are to be used as energy absorbers
• functional parts
• all types of bumpers, vibration dampers
• guides
• protective cases
• snap-fit ​​parts
• sleeves
• hinges
• bumpers and flexible spacers,
• sealing parts with increased rigidity,
• spring damping elements for use in machine manufacturing and modelling,
• high resistance flexible bands,
• covers and housings for various devices,

Packaging

The filament is wound on the neat and transparent spool. Each spool contains information about the material type, diameter and recommended printing temperature. The filament is vacuum packed with a moisture absorber. The entire product is packaged in the original Spectrum Filaments foil-lined packaging.
