The effect of medical TPU waterproof and breathable film as medical protective clothing

The application effect of medical TPU waterproof and breathable membrane in medical protective clothing is very significant. With its unique polymer structure, this material achieves a good balance between waterproof and breathable properties. In terms of waterproofing, the TPU membrane has a dense structure and can effectively block the penetration of harmful substances such as blood, body fluids, droplets, viruses and bacteria, and provides a reliable protective barrier for medical staff. In terms of moisture permeability, the TPU film utilizes the movement of polymer chain segments and the conduction of water molecules between chain segments, allowing water vapor emitted by the human body to be discharged through the film, significantly reducing the feeling of stuffiness and humidity inside the protective clothing, allowing the wearer to stay dry and comfortable during long hours of work.

Compared with traditional polyethylene film protective clothing, the comfort of protective clothing using TPU film is greatly improved, reducing physical exertion and the risk of collapse caused by excessive sweating, and also reducing the possibility of cross-infection during the process of taking off protective clothing. In addition, the TPU material itself is soft and elastic. When combined with non-woven fabric, it feels comfortable to the touch, has high tensile strength, is resistant to folding and friction, and is not easily damaged during strenuous activities such as bending down and lifting arms, ensuring the integrity of the protection. TPU also has good chemical resistance and can withstand daily disinfection treatments such as alcohol wiping. Its environmentally friendly and non-toxic characteristics also meet the safety requirements of medical supplies. Taken together, TPU waterproof and breathable membrane allows medical protective clothing to reach a high level in terms of protection, comfort and durability, and is one of the important development directions in the current field of medical protective materials.
