Precimid1130 88A
Precimid1130 88A | TPU Powder (Natural White)
Precimid1130 88A is a natural white TPU powder with a Shore A hardness of 88–90 for SLS 3D printing. It is flexible, impact resistant and fatigue resistant, and reliably returns to its shape after deformation – ideal for cushioning and moving parts.
- Flexible: Shore A hardness of 88–90 and elongation at break up to 270%.
- Elastic: High rebound resilience of 63% and low compression set.
- Fatigue resistant: No cracks in the Ross flex test, even at −10 °C.
- Durable: Resistant to water, heat and mold.
