What material is the airway of the gas mask link made of?

      The airway of a gas mask is usually made of high-temperature and corrosion-resistant materials to ensure that the mask can properly discharge exhaled exhaust gas during use. Common materials for air ducts include silicone, polyvinyl chloride (PVC), rubber, etc.

      Silicone is usually one of the selected materials for air ducts because it has good flexibility and high-temperature resistance, and can withstand hot air flow at higher temperatures, making it suitable for use in high-temperature environments. In addition, silicone also has excellent corrosion resistance and chemical resistance, which can ensure that the airway is not corroded when in contact with chemicals, maintaining its service life and stability.

      Polyvinyl chloride (PVC) is also a common material for air ducts. PVC has good wear and corrosion resistance, can withstand pressure and tension, and is not easily deformed or damaged during mask use. In addition, PVC material also has good formability and low cost, making it suitable for mass production and application in the production of gas masks.

Rubber is also one of the common materials for air ducts. It has excellent elasticity and tensile properties, which can ensure that the air duct of the mask is not easily deformed or damaged during use, and maintain the sealing and stability of the mask. In addition, rubber materials also have certain corrosion resistance and can adapt to a certain range of chemical environments.

      In general, the airway of gas masks is usually made of materials such as silicone, polyvinyl chloride (PVC), rubber, etc. to ensure that the airway can work normally in high temperature and corrosive environments, ensuring the safety and health of users. Different materials have their own advantages and applicability, and manufacturers will choose suitable materials for the specific use and environmental requirements of the mask to ensure its performance and quality.
