Silicone bottle is made of liquid silica gel (LSR) bottle, do not contain bisphenol A, also won't broken, excellent transparency, resistance to tear strength, resilience, yellow degeneration, heat aging resistance and weatherability.
When making the bottle, the viscosity of silica gel is moderate, easy to operate, and the product transparency is high. It can be seen whether the casting material in the mould has the defects such as bubble, the line shrinkage rate is less than 0.1%, and the reproduction size is precise.
Feeding bottles are divided into three types: first-generation 1G (Glass), second-generation 2G (Plastic PP\PES\ PPSU) (Plastic) and third-generation 3G (Silicone).
Silicon is the most abundant element on earth after oxygen. Large amounts of silicon can be found in various minerals and it is abundant in oceans and nearly all other waters as silicic acid. In the surface layers of oceans silicon concentrations are 30 ppb, whereas deeper water layers may contain 2 ppm silicon. Rivers generally contain 4 ppm silicon. Silicon is usually not ionized when dissolved; it is present as ortho silicic acid (H4SiO4 or Si(OH)4). These compounds are the result of slow dissolution of silica in water. Rivers transport large amounts of silicon to sea. Most likely, less than 20% of dissolved silicon is removed from rivers by means of biological or chemical transformation processes.
