TPU 70A Filament
TPU 70A Filament is a soft and highly flexible thermoplastic polyurethane designed for applications that require a more rubber-like feel, strong elasticity and repeated deformation. Compared with standard 95A TPU, the softer 70A hardness provides greater flexibility and cushioning performance while maintaining good resilience and durability.

Product Description
TPU 70A Filament is developed for applications that require a softer, more rubber-like material with high flexibility and strong elastic recovery. Compared with standard 95A TPU, the lower 70A hardness allows printed parts to bend, compress and deform more easily, making it especially suitable for products that need cushioning, soft-touch performance or repeated movement.
The material offers good resilience, impact resistance and abrasion resistance while maintaining the flexibility needed for demanding functional parts. Its softer structure makes it a practical option for wearable components, flexible covers, protective pads, seals, grips and other parts that need to adapt to movement or contact surfaces.
With stable extrusion and consistent filament diameter, TPU 70A can be used for both prototyping and customized production where a softer flexible material is required.
For B2B customers, Tecsonar supports bulk orders, private labeling, customized packaging and color development according to project requirements, making TPU 70A Filament a suitable choice for manufacturers, distributors and 3D printing service providers seeking highly flexible TPU solutions.
Choose the Right TPU Hardness
Tecsonar offers a wide range of TPU hardness options for different application requirements. Softer grades provide greater flexibility and a more rubber-like feel, while harder grades offer increased structural support, dimensional stability and resistance to deformation.
TPU 70A Positioning
TPU 70A is one of the softest grades in the Tecsonar TPU portfolio. It is particularly suitable for applications that require substantial deformation, cushioning, repeated bending and a soft-touch surface.

Applications
TPU 70A Filament is especially suitable for parts that need significant flexibility, cushioning and repeated deformation during use. Typical applications include soft protective pads, flexible covers, wearable components, seals, grips, shock-absorbing parts, soft-touch accessories and customized flexible products.
Its softer, rubber-like feel also makes it useful for products that need to conform to curved surfaces or provide a more comfortable contact area, such as wearable accessories, flexible inserts, protective components and ergonomic parts.
