Flexibility with excellent impact resistance and thermal insulation
Spectrum S-Flex 85A is a filament based on thermoplastic polyether polyurethane. In additive manufacturing, S-Flex 85A is a material characterized by a relatively simple and error-free 3D printing process. An additional advantage leading to 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 another material.
Low processing shrinkage and high flexibility significantly reduce the risk of so-called curling of the edges of manufactured parts. The distinctive feature in the filament name 85A is related to the material's hardness on the Shore scale and classifies Spectrum S-Flex 85A in the hard elastomer category. This property, from the perspective of the 3D printing process, reduces the risk of filament deformation in the feeding system that delivers 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 hydrolysis resistance (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 protective elements with high chemical resistance, as well as thermal insulators.
Main features:
- high hydrolysis resistance
- up to 650% elongation at break
- 85 Shore-A hardness
- high tensile and tear strength
- low shrinkage
- resistance to many common industrial oils and chemicals
- reduced stringing while the printer is idle
Applications:
- production of seals with high chemical resistance
- production of items to be used as energy absorbers
- functional parts
- all kinds of bumpers, vibration dampers
- guides
- protective housings
- snap-fit parts
- sleeves
- hinges
- flexible bumpers and spacers,
- sealing parts with increased rigidity,
- spring damping elements for use in machine production and modeling,
- high-strength flexible bands,
- covers and housings for various devices,
Packaging
The filament is wound on the ordered and transparent spool. Each spool contains information on the type of material, diameter and recommended printing temperature. The filament is vacuum-packed with a moisture absorber. The entire product is packed in the original film-coated Spectrum Filaments packaging.
