The reason why polyurethane foam is suitable as the main material for medical foam dressings is that it has many excellent properties, making it play a key role in wound management.
Polyurethane foam has excellent elasticity and softness and can closely adhere to the wound surface. This good fit can not only reduce the contact between the wound and the external environment, reduce the risk of infection, but also effectively prevent the wound from further damage. At the same time, the softness of polyurethane foam also provides patients with a more comfortable experience and reduces discomfort during wound care.
Polyurethane foam has excellent absorbent properties. It quickly absorbs fluid from wounds and keeps them dry, helping to reduce the risk of bacterial growth and infection. At the same time, the polyurethane foam that absorbs exudate can form a moist environment to help promote wound healing.
Polyurethane foam also has good air and moisture permeability. It allows air and moisture to circulate on the wound surface and maintains appropriate humidity in the wound environment, thereby aiding wound recovery. At the same time, this breathability also helps reduce discomfort and odor at the wound site.
The most important point is that polyurethane foam has good biocompatibility and is non-toxic and harmless to the human body. It undergoes rigorous manufacturing and sterilization processes to ensure there is no additional risk of infection to the wound during use.
