Food grade silicone materials

Food grade silicone is made of silicate polycondensation of inorganic polymer gel material, its main ingredients are mSiO2 · nH2O, its content is over 98%, stable chemical features, under the normal temperature state except hydrofluoric acid and caustic, not any response from the acid and alkali salt. Because it is a kind of colloid structure, thus has a lot of microporous and great product than appearance. Edible silica gel pore size of about 8 to 10 nm, than appearance product 300-500 m2 / g, hydrophilic, coupled with the appearance of water has a strong absorption capacity, in the water absorbing capacity under high moisture conditions can be up to 80% by weight of the person – more than 100%. And food grade silica gel can be used as food, medicines for external use desiccant. Due to consumption of silica gel is a refined and after sterilization, can be merged and the food and drug according to the necessary quantity direct guarantee food drying and food to eat at the same time, therefore not harm to our healthy.
The features of food grade silicone material:
1.Non-toxic, no smell, high TouLiangDu, no yellowing;
2.Soft, good elasticity, resistance to kink deformation
3. No crack, long service life, hardy resistance to high temperature
4. A higher tear strength and superior electrical functions
It has high TouLiangDu, boring, yellowing, don’t spray frost, such as strength, especially with the black rubber spray cream, blue products fade, soft, high resistance to tear, high insulation, wear resistance, high temperature resistant, flame retardant, aging resistance, environmental protection,
