Compared with other materials, silicone resin has the following unique advantages in the medical industry:
Excellent biocompatibility
Silicone resin has minimal irritation to human tissues. After implantation, the immune and inflammatory responses produced by the body are very weak, and it can coexist harmoniously with the physiological environment of the human body. For example, in the production of implantable components such as artificial joint pads and heart valves, compared to the rejection reactions that may be caused by some metal materials and the local inflammation that may be caused by some polymer materials, silicone resin can better maintain long-term stability in the human body, reduce the occurrence of complications, and ensure the health of patients and the effectiveness of the implanted components.
Good chemical stability
It has strong tolerance to various chemical substances in the human body, such as acidic and alkaline environments, biological enzymes, body fluid components, etc., and will not easily react with them to corrode, decompose or denature. In the complex chemical environment of long-term exposure to the human body, such as placing medical catheters in blood vessels, urinary tract and other areas for a long time, silicone resin can maintain its physical and chemical stability, and maintain its normal function, unlike some ordinary plastic materials that may experience aging, brittleness or even damage due to the influence of internal chemicals.
Excellent flexibility and elasticity
Silicone resin molecular chains are relatively flexible, and the material has good flexibility and elasticity, which enables it to simulate the mechanical properties of human tissue very well. For example, in the production of soft tissue substitutes such as artificial bladder and blood vessels, they can undergo corresponding deformation with normal physiological movements of the human body (such as bladder filling and emptying, blood vessel pulsation with heartbeat, etc.), and can restore their original state after deformation, avoiding damage to surrounding tissues due to excessive rigidity, which is an advantage that many rigid materials find difficult to possess.
Excellent heat and cold resistance
The body temperature of the human body fluctuates within a certain range, and may also face temperature changes in some medical operations and external device usage scenarios. Silicone resin can maintain stable performance in a wide temperature range (usually from low to high temperatures, such as withstanding temperatures of around -50 ℃ to 200 ℃). Medical dressings can maintain their protective effect on wounds in different seasons and environmental temperatures, while some thermoplastic materials may become hard and brittle at slightly lower temperatures, affecting their effectiveness. Silicone resin does not experience such situations.
High breathability and permeability (in some application scenarios)
For some medical products that require contact with human skin or mucous membranes and ensure gas and water exchange, such as wound dressings, oxygen masks, etc., silicone resin has moderate breathability and permeability, which can create a moist environment conducive to wound healing or ensure smooth and comfortable breathing for users. While meeting the corresponding functional requirements, it is different from materials that are completely impermeable and not breathable, and is more in line with the actual requirements of medical use.
Easy to process and shape
Silicone resin can be easily processed into various shapes and sizes of medical products through various methods such as injection molding, extrusion, and compression molding, which can meet the complex and diverse design needs of different medical application scenarios. From small catheters to large artificial organ shells, it can be efficiently manufactured. Compared with some materials with complex processing techniques and difficult molding, it has more advantages in the production and manufacturing of medical products.
Physiological inertia and anticoagulant properties (in some application scenarios)
Silicone resin usually exhibits physiological inertness and is not conducive to the growth of bacteria, fungi, and other microorganisms, reducing the risk of infection. And in some applications involving blood contact, such as vascular catheters, they have certain anticoagulant properties, which can reduce the probability of thrombosis and ensure the normal use of medical equipment in the blood environment. This is a characteristic that many other ordinary materials cannot match, which is very important for ensuring the safety of patients' lives and the smooth progress of medical operations.
