1. Medical devices and coating materials
Silicone has become a core material for medical device manufacturing due to its excellent biocompatibility, chemical stability and corrosion resistance. In medical coatings such as surgical instruments, dental instruments and sutures, silicone coatings can significantly improve the wear resistance, antibacterial and corrosion resistance of the instruments while avoiding allergic reactions. For example, Elkem Silicones' bio-grade and drug delivery-grade silicone rubber solutions are used in airway stent coatings to enhance the corrosion resistance and strain resistance of the stents and reduce tissue ingrowth. In the field of medical catheters, silicone materials are widely used in the manufacture of disposable devices such as intravenous cannulas and peritoneal dialysis tubes due to their hypoallergenic, sterilizable and easy processing properties, ensuring patient tolerance and reducing the risk of infection.

2. Artificial organs and implant materials
Silicone shows unique advantages in artificial organs and implants. Its good biocompatibility, mechanical properties and long-term stability make it an ideal material for key components such as heart valves, lung membranes, and breast fillers. For example, artificial heart valves made of silicone rubber can maintain normal function in the body for 20 years, and there is almost no platelet adhesion and thrombosis on the surface. In plastic surgery, silicone gel is used as a breast filler and padding material, providing patients with a comfortable wearing experience due to its light weight, softness and resilience. In addition, the application of silicone elastomers in prosthetic pads can effectively protect the skin of residual limbs and reduce the pain of amputees.

3. Drug carriers and wound care materials
Silicon plays an important role in drug delivery systems and wound care. As a drug carrier, mesoporous silicone nanoparticles can achieve controlled release of drugs through factors such as pH, light or ultrasound, significantly improving the effect of cancer treatment. For example, a hierarchical composite nanosystem based on pH response can accurately deliver anticancer drugs to deep areas of tumors. In the field of wound care, silicone dressings can promote wound healing and reduce the risk of infection due to their breathability, moisture retention and antibacterial properties. The use of Elkem silicone materials in absorbent foam wound dressings and postoperative dressings enables non-invasive and painless wound access and removal, while supporting repeated application of adhesive bandages, making it easier for doctors to observe wound recovery.
