Is the TPU waterproof layer breathable

The TPU waterproof layer has breathability.

The TPU waterproof layer has breathability, which is achieved through its hydrophilic properties. TPU waterproof breathable film itself has no pores, relying on the difference in steam pressure inside and outside the clothing to transfer steam from high pressure areas to low pressure areas, thereby achieving moisture permeability. This material is commonly used to make waterproof and breathable fabrics, which have good waterproof effect and also have breathable characteristics, making the fabric windproof and warm. ‌

TPU waterproof and breathable film has a wide range of applications, including footwear, pharmaceuticals, and other fields. This material can effectively exchange gases while maintaining waterproof performance, meeting the needs of different fields.
