Yoline Lab offers a complete TPU hardness range spanning from ultra-flexible 85A to engineering-grade 72D, covering five distinct performance grades. Each grade is formulated for specific applications, allowing users to select the precise balance of flexibility, strength, and printability their project requires.

Why a Complete Hardness Range Matters

Most filament brands offer one or two TPU hardness options — typically a generic 95A. But flexible material applications are incredibly diverse. A phone case, a drone landing pad, an industrial roller, and an automotive gasket all need different mechanical properties from their material.

Yoline Lab developed a full hardness spectrum so users can select the right material for the application — not compromise on whatever happens to be available.

The Complete Yoline Lab TPU Lineup

TPU85A — Ultra-Soft Flexibility

Feel Reference: Soft sports protection pads

TPU85A is the softest material in the Yoline Lab TPU lineup, offering exceptional flexibility, elasticity, and comfort.

Key Characteristics:

• Maximum softness and flexibility in the TPU range
• High elasticity and stretch capability
• Excellent comfort for skin-contact applications
• Softest printing experience

Recommended Applications:

• Wearable products and accessories
• Soft-touch consumer goods
• Phone cases prioritizing grip and cushioning
• Sports protection equipment
• Flexible cushioning and padding components

Best for users who prioritize softness and elasticity above all else.

TPU90A — High Elasticity and Fatigue Resistance

Feel Reference: Traditional phone case material

TPU90A delivers excellent elasticity while providing improved structural strength compared to TPU85A. It offers one of the best balances between flexibility and durability in the lineup.

Key Characteristics:

• High elasticity with excellent rebound
• Improved structural strength over 85A
• Strong fatigue resistance for repeated flexing
• Good vibration dampening properties

Recommended Applications:

• Drone landing gear dampers
• RC model components
• Shock-absorbing parts
• Flexible connectors and hinges
• Vibration isolation components

Best for users who need elastic performance with structural integrity.

TPU95A — The All-Round Flagship

Feel Reference: Sports shoe sole

TPU95A is the most versatile TPU in the Yoline Lab portfolio and the grade recommended for most users and general-purpose applications.

Key Characteristics:

• Excellent printability and ease of use
• High-speed printing capability up to 500mm/s
• Strong layer adhesion for durable parts
• High abrasion resistance
• Balanced flexibility and strength
• Stable feeding without auxiliary extrusion

Recommended Applications:

• Functional parts across multiple categories
• Robotics projects and components
• Consumer electronics accessories
• Industrial fixtures and tooling
• General-purpose TPU applications

Best for users who want the best all-around flexible material — and the safest choice if you're unsure which TPU to select.

TPU98A — High-Rigidity Flexible Material

Feel Reference: Shopping cart wheel

TPU98A provides significantly higher rigidity while retaining TPU toughness and impact resistance. It's the choice when you need strength and dimensional stability without giving up TPU's signature durability.

Key Characteristics:

• High rigidity for a flexible material
• Excellent impact resistance
• Good dimensional stability
• Suitable for long-duration production runs
• Retains TPU toughness and wear resistance

Recommended Applications:

• Rollers and wheels
• Protective housings and covers
• Durable functional parts
• Industrial components
• Long-duration production printing

Best for users who need strength and stability but still want TPU's impact performance.

TPU72D — Engineering-Grade TPU

Feel Reference: Engineering plastic

TPU72D bridges the gap between traditional flexible TPU and rigid engineering materials. Although technically a TPU, its performance and feel are much closer to engineering plastics than traditional flexible filaments.

Key Characteristics:

• Highest tensile strength in the TPU series
• Exceptional impact resistance
• Excellent oil resistance
• Excellent weather resistance
• Outstanding dimensional stability
• Closest feel to rigid engineering plastics

Recommended Applications:

• Industrial jigs and fixtures
• Mechanical components
• Automotive applications
• Manufacturing aids and tooling
• Engineering prototypes

Best for users who need engineering-grade performance with TPU's unique toughness and impact properties.
