1.The Breathable PU is mainly applicable to production of insoles, with good physical properties(elasticity, tear, compression ratio, air permeability, etc.), which have the propertise of traditional perfusion PU, and the air permeability of PU foam. The product overcomes the impenetrability of traditional perfusion PU, and compares the physical propertise of PU foam. 2.This material is suitable for forming any style insoles, with clear lines, good fluidity, compression ratio, rebound rate, tear, elongation,etc.
