Silicone is a highly active adsorbent material, belonging to the amorphous state. Its main component is mSiO ₂ · nH ₂ O, which is chemically stable, non flammable, insoluble in water and any solvent, non-toxic and odorless. It does not react with any substance except strong bases and hydrofluoric acid. High temperature and low temperature resistance, aging resistance, corrosion resistance, softness and toughness.

The biggest characteristic of rubber is its elasticity, wear resistance, cold resistance, and resistance to air leakage. The biggest drawback is that it is prone to aging. The chemical properties are inferior to those of silicone.

Comparing the characteristics of silicone and rubber, it is obvious that the sealing ring is better than silicone. Silicone sealing rings are widely used in household appliances, rice cookers, boiling kettles, insulated cups, food machinery and other mechanical equipment that come into contact with food. Rubber sealing rings are widely used in electric tools, industrial equipment, lathe equipment, engines, air compressors, mechanical equipment, etc.
