High Strength and High Toughness
TPU (thermoplastic polyurethane) exhibits exceptional tensile strength and tear resistance, enabling it to withstand repeated compression and impact without fracturing. For example, TPU airbags can rapidly inflate during collision tests while maintaining structural integrity, effectively dissipating impact forces to protect lumbar safety.
Superior Wear Resistance
TPU significantly surpasses conventional rubbers and plastics (e.g., PVC, EVA) in abrasion resistance, making it ideal for long-term use. The lumbar cushion airbag resists wear from daily friction, extending its service life.
Elasticity and Resilience
TPU combines the elasticity of rubber with the rigidity of plastics, offering excellent rebound properties to swiftly return to its original shape. The lumbar cushion airbag provides soft support when inflated and quickly regains its shape after deflation, ensuring lasting comfort.
Broad Hardness Range
By adjusting the formulation, TPU hardness can be tailored from 60A (soft) to 85D (rigid) to meet diverse support requirements. For instance, soft-grade TPU suits users prioritizing a gentle tactile experience, while rigid-grade TPU delivers firmer support.
