Spectrum Filament S-Flex 85A
Hyper-Flexible TPU | Laser Lime | 0.25-0.5kg Pro Mini Spool
Spectrum S-Flex 85A is a specialized thermoplastic polyurethane (TPU) formulated for applications where maximum flexibility and superior damping are required. With a Shore hardness of 85A, this filament delivers parts that are significantly softer than standard TPUs, offering a tactile sensation similar to high-grade silicone or soft rubber.
The Laser Lime variant provides exceptional visual clarity and high visibility, perfect for safety-critical components or bold artistic prototypes. Despite its softness, S-Flex 85A maintains high tear resistance and impressive chemical durability, making it a robust choice for functional industrial use.
🧸 Unmatched Flexibility
Superior elasticity and a soft durometer allow for extreme bending and twisting without permanent deformation.
🔇 Superior Energy Damping
Engineered to absorb high-impact energy and dissipate vibrations, protecting delicate internal electronics and optics.
🛢️ Robust Chemical Resistance
Resistant to common automotive oils, greases, and many industrial chemicals, ensuring long-term part stability.
🌬️ Hermetic Reliability
Achieves exceptional layer fusion, making it ideal for creating complex, leak-proof gaskets and air-tight bellows.
- Ultra-soft vibration isolators and dampeners
- Custom seals for fluid and air systems
- Wearable medical and sports prototypes
- Non-slip feet and ergonomic grip skins
- Protective bellows and dust covers
- High-flexion hinges and soft robotic grippers
