Frequently Asked Questions
What hardness range is available for TPU?
TPU spans 60 Shore A (soft as a pencil eraser) to 75 Shore D (hard as a skateboard wheel). The polyester-based grades offer better oil/chemical resistance; polyether-based grades offer better hydrolysis resistance for medical and underwater applications.
