Why is silicone rubber widely used in respiratory masks?
A:
Respiratory masks used in medical clinics and health care fields have very high requirements on materials because of direct contact with medical staff and patients. The silicone rubber material has become a very ideal medical respiratory mask material because of its unique advantages.
Specifically, it is soft and has excellent biocompatibility to reduce sensitization, can fit closely with the face, is environmentally friendly, non-toxic, and comfortable to wear. For example, the series of silicone rubbers can greatly improve skin-friendliness and comfort on the basis of ensuring safety performance due to its simple and pure composition and soft elastomer material properties.
Q:
Is there a reduction in safety due to the comfort of the respirator?
A:
The safety and reliability of medical supplies will always be paramount. As a raw material, the safety and reliability of silicone is reflected in its simple composition, excellent biocompatibility, and its unique silicon-oxygen main chain molecular structure endows it with excellent mechanical properties, as well as high and low temperature resistance, ozone resistance, and radiation resistance. capacity, etc., can meet the requirements of repeated disinfection.
Q:
Compared with other materials, what are the advantages of silicone rubber in the medical field?
A:
Compared with PVC materials, silicone rubber can achieve a very soft effect without adding plasticizers. Compared to latex materials, there is no risk of sensitization. Compared with thermoplastic elasticity, it has more reliable temperature resistance and pressure change resistance.
Silicone elastomer materials are currently widely used in the medical field, such as medical hoses (breathing hoses, urinary catheters, infusion tubes, peristaltic pump tubes, drainage tubes, etc.) produced by extrusion molding process, by injection molding or molding Structural components (respiratory masks, breathing bellows, valves, diaphragms, seals, medical device handles, etc.) processed by the molding process.
In addition, the reusable and sterilizable children's masks currently on the market are also similar to the requirements of respiratory masks, and silicone materials continue to expand the scope of application due to their unique advantages.
