What are the identification methods of food grade silicone hose and medical grade silicone hose?
What is the method to distinguish between food grade silicone hose and medical grade silicone hose? The main reason is that there are some differences in performance between the two, but the sanitary grade of medical grade silicone hose is higher than that of food grade silicone hose. It can be said that medical grade silicone hose can be used as food grade silicone hose. On the contrary, it is not. Some food grade silicone hoses can be used in the medical industry.
Characteristics of food grade silicone hose:
Food grade silica gel is a kind of environmental friendly silica gel, non-toxic, tasteless and high transparency;
Soft, good elasticity and anti distortion;
No cracking, long service life, low temperature and high temperature;
It has higher tear strength and superior electrical properties.
At room temperature, it will not turn yellow, spray frost, spray white and fade. There is no residue and smell in the water for a long time.
Characteristics of medical grade silicone hose:
Medical grade silicon hose, cold and high temperature resistant, weak acid and alkali resistant, harmless, non-toxic and tasteless;
High transparency, high elasticity and strong UV resistance;
Good elasticity, torsion resistance, no deformation, softness, arc resistance, anti-corona, chemical stability, physiological inertia, non-toxic, non irritating to human body, hydrophobicity, air permeability, excellent elasticity, permanent deformation and other characteristics. It can be used under high temperature conditions from - 50 ° to 250 ° C. special requirements are barrier free and excellent insulation performance.
It can be disinfected with ethylene oxide.
Meet the food and drug inspection standards, keep color at room temperature not turn yellow, do not spray cream, do not spit white, do not fade, and do not scale in water for a long time.
