Spectrum Filament S-Flex 98A
Premium TPU Elastomer | 0.25kg-0.50kg Precision Spool
Spectrum S-Flex 98A is an advanced thermoplastic polyurethane (TPU) filament designed for users who require both mechanical durability and ease of use. With a Shore hardness of 98A, it sits at the perfect intersection of flexibility and structural integrity, making it one of the most printable elastomers on the market.
The striking Lime Green color is not just aesthetic—it provides high visibility for industrial safety components, prototypes, and creative designs. S-Flex 98A is exceptionally resistant to abrasion and tearing, ensuring that your functional parts can withstand harsh environments and repeated dynamic stress.
⚡ Exceptional Elastic Recovery
Highly resistant to permanent deformation; parts return to their original shape quickly after compression or stretching.
🧪 Chemical & UV Resistance
Outstanding resistance to oils, greases, and common industrial solvents, combined with good stability against UV radiation.
🛠️ Easy Printing (98A)
The higher hardness compared to ultra-soft TPUs allows for higher printing speeds and better compatibility with Bowden extruders.
💧 Waterproof Seals
Excellent interlayer bonding creates airtight and watertight structures, perfect for gaskets, seals, and protective cases.
- Industrial gaskets, seals, and spacers
- Vibration dampeners and shock absorbers
- Protective housings and impact bumpers
- Flexible hinges and snap-fit components
- Custom footwear inserts and wearable prototypes
- Safety-marked industrial tool grips
