Function: Reduce vibration and noise during the operation of mechanical equipment.
The core advantages of ETPU
Performance | ETPU Characteristics | Comparison with Traditional Materials (such as EVA, PU) |
---|---|---|
Elasticity | High resilience (over 60%) | EVA resilience is only 40% - 50% |
Durability | Compression - resistant deformation (permanent deformation ≤20%) | PU is prone to hydrolysis, EVA is prone to collapse |
Weight | Ultra - light (0.1 - 0.3g/cm³) | 50% lighter than rubber |
Temperature Adaptability | Stable use from -40°C to 90°C | EVA becomes brittle at low temperatures |
Environmental Protection | Recyclable, pollution - free | PU is difficult to degrade |
