Mechanical Properties Of EM⁺21
Tear Strength
Tensile Strength
Shore A Hardness
Elongation at Break
EM+21 is a high-performance elastic material with superior resilience, tear resistance and bending resistance. EM+21 cooperates with LEAP ultra-fast 3D printing technology and parametric design, the model size is controlled accurately, and the details are perfect. It is widely used in sports shoe midsoles, industrial cushioning, personal wear and other high-rebound cushioning and multiple bending fields. EM+21 passed the "ISO 10993-10:2010 Biological evaluation of medical devices-Part 10:Tests for irritation and skin sensitization"
