Frequently Asked Questions: TPU 64D

What is TPU 64D?

TPU 64D is a semi-rigid thermoplastic polyurethane with a Shore 64D hardness rating. It offers greater structural rigidity and wear resistance than typical flexible TPU materials while maintaining controlled flexibility for impact absorption. This material combines the toughness of rigid plastics with strategic compliance, making it ideal for mechanical parts requiring durability with some flex.

How hard is a 64D TPU?

Shore 64D TPU is considered semi-rigid and falls on the Shore D hardness scale, which measures harder materials. It's significantly more rigid than Shore A scale TPU materials like 85A or 95A. Think of it as having rubber-like toughness with substantial structural integrity, harder than a pencil eraser but softer than rigid plastics like ABS or PLA.

Is 64D softer than 85A?

No, 64D is actually harder and more rigid than 85A. The confusion comes from different hardness scales: Shore D measures harder materials while Shore A measures softer materials. Shore 64D translates to approximately 95A-98A on the Shore A scale, making it considerably more rigid than 85A. 85A provides rubber-like flexibility while 64D offers semi-rigid structural performance.

What is the difference between TPU 85A and 64D?

TPU 85A is softer and more flexible with rubber-like elasticity, ideal for grips, cushioning, and applications requiring significant flex. TPU 64D is semi-rigid with greater structural stability, better suited for mechanical parts, gears, and components needing toughness with controlled flex. 64D offers superior wear resistance and dimensional stability under load, while 85A provides maximum flexibility and comfort.
