1, Structure: Silicone is a compound with silicon and carbon in its molecular structure. It can be linear, cyclic or cross-linked structure. Polyglutamic acid is a natural polypeptide composed of glutamic acid units, which belongs to biopolymer compounds.
2. Physical properties: Silicone has many special physical properties, such as high temperature resistance, chemical corrosion resistance and low surface tension. It can maintain stability and special functions in various environments. Polyglutamic acid has good water solubility and large molecular weight, and can form viscous solution.
3. Application field: Because of its excellent performance, silicone is widely used in many fields, such as architecture, automobile manufacturing, electronic equipment, medical devices and so on. It can be used as sealant, lubricant, waterproof agent, adhesive, etc. Polyglutamic acid is often used in cosmetics and skin care products because of its moisturizing, antioxidant and anti-wrinkle effects.
