Silica gel is an environmentally friendly material that everyone agrees with. Food grade silica gel can provide US FDA177.2600 test and is a material that can be contacted with food. In addition, silica gel has no smell and does not smell uncomfortable. In addition, silica gel is a chemically stable material, and human skin does not have any discomfort or allergy when contacting silica gel.
As for TPE,TPR. This is a kind of soft material that has been increasingly used in rubber and plastic industry in the past 10 years. TPE,TPR is environment-friendly and non-toxic. Through the detection of SGS third-party organizations, TPE|TPR conforms to ROHS,REACH(SVHC), and does not contain toxic o-benzene plasticizer, bisphenol A, nonylphenol NP and polycyclic aromatic hydrocarbons PAHs. It also does not emit unpleasant smell to human body. TPE is mild in nature and does not have allergic effect when skin comes into contact with it. TPE meets ISO10993 Biocompatibility Test.
Silicone and TPE can both provide materials suitable for hardness, finding a balance between facial contact comfort and material strength. currently, soft rubber TPE and silica gel used in gas masks usually have hardness of 45 ~ 50 a. at the same time, TPE and silica gel both have good low temperature resistance (both can maintain soft elasticity at-50 c)
