Product description

MTPU is microcellular TPU foam, produced using thermoplastic polyurethane (TPU) as the composition with clean supercritical carbon dioxide as blowing agent to form a large number of microcells in the matrix.

Characteristic:

• Light weight
• Clean and environmental friendly
• Good cushion performance
• Excellent low temperature resistance
• Good chemical resistance
• Recyclable
• Outstanding resilience
• High tensile strength
