Description
Inslogic TPU 90A Filament
Industrial grade flexible plastic filament (Shore 90A), tough, durable, and easy to print, for engineering and wearables applications.
Product description
A perfect balance between softness and engineering strength, Inslogic TPU 90A is a thermoplastic polyurethane (TPU) filament with a Shore hardness of 90A. It's designed to be softer and more flexible than typical TPU 95A, making it ideal for applications requiring rapid elastic memory and excellent shock absorption.
Key features that make the Inslogic TPU 90A stand out:
-
Superior flexibility and recovery: With an elongation at break of over 1000%, the material can be stretched or bent without breaking and returns to its original shape with up to 92% accuracy.
-
Skin-Friendly: The special zinc-based formula minimizes skin irritation, making it ideal for printing wearables, watch straps, or device handles.
-
Environmentally resistant: Features UV protection and heat resistance, reducing problems such as yellowing or cracking of items after prolonged use or outdoor exposure.
-
Tear and chemical resistant: Resistant to abrasion, oil, and many chemicals, making it suitable for machine parts and various seals.
-
Easy and smooth printing: Designed for consistent line flow, reducing stringing problems and ensuring strong interlayer adhesion.
Proper usage:
-
Wearable devices such as smartwatch straps and protective cases.
-
Vibration dampers and rubber bushings.
-
Seals, gaskets, and flexible joints.
-
RC car tires and soft-touch tool handles.
