Longyixing Chemicals
This waterproof & moisture permeable TPU adopts hydrophilic solution-diffusion structure, blocking liquid water infiltration while efficiently discharging internal water vapor, featuring high hydrostatic pressure resistance, excellent moisture transmission, great elasticity, wash resistance and stable low-temperature flexibility.
It balances long-term waterproof durability and wearing comfort, available in polyether & polyester grades to match hydrolysis resistance or high mechanical strength demands for different scenarios.
It is widely laminated for outdoor jackets, ski apparel, functional footwear, medical protective clothing, tent fabrics, home textiles and other moisture-wicking waterproof composite fabric applications.
