        Engineers evaluate essential differences between tpu and pvc when designing critical healthcare components. Standard TPU provides superior durability, elasticity, and plasticizer-free biocompatibility for high-performance products. Conversely, standard PVC offers lower upfront material costs for budget-driven short-term medical products. Material selection directly impacts overall product service life, patient safety, and strict regulatory compliance.
