2.2 For medical tape and film

Silicone materials can help surgical films (and incision membranes) in the skin to better fixation, thereby reducing the risk of infection in the patient during the surgical incision process. Its efficient bonding performance and repeatable adhesive properties make this product ideal for the manufacture of medical tapes and films.

Silicone technology solutions are used to reduce pain and irritation to wounds. Adhesive bandages using silicone flexible skin adhesives can be firmly attached and easily removed, reducing skin irritation. At the same time, this series of products can make the adhesive bandage repeat application, which helps doctors observe the recovery of the patient's wound during treatment.
