Gas principal advantage of the silica gel mask can be repeated use, unlike ordinary fiber filter mask, although it is the price will be more expensive than disposable mask some, but in the case of no mask is stronger "silicone rubber masks the initial reason is gas, used in some special environment, so a lot of old gas silica gel mask are heavy, not suitable for wearing in the normal use of the estimated antivirus effect cannot achieve the best effect, and now with the constant improvement of product function improvement and design, the function will naturally prevent virus popular at present, gas silica gel mask can prevent and control the virus for you!From the point of the understanding of materials, liquid silicone rubber has long been used in the medical treatment of the necessities of life, level medical equipment accessories, it not only has good biocompatibility physical advantages, in use process also has good tensile strength and service life as a ear with extended rate material advantages of soft and comfortable, so the mask production nature is appropriateMedical grade silicone antivirus mask is in grade clean workshop production, according to standard medical silica gel test, under the catalysis of catalyst, the qualified high molecular weight poly (dimethyl and methyl ethyl methyl siloxane and chain resistance agent divinyl two siloxane polymer, clear and transparent appearance, good resistance to yellow, not easy deformation, high tear resistance, suitable for high strength products.

It is made of food grade high quality silica gel. Double-layer silica gel edge is adopted to make it close to the face. The corrugated design mask can meet the requirements of different face shapes.S

ilicone material can seal most of the harmful gases, will not age hard, easy to clean, very durable.
