Basic information:
Methylcellulose is a polymer with a range of physical and chemical properties. Here is a brief introduction to methylcellulose:
Physical properties:
Form: Methylcellulose is usually a white to slightly yellow powdery substance, and can also be in fibrous or flake form.
Solubility: Methylcellulose dissolves in water to form a colloidal solution with good solubility.
Thermal stability: Methylcellulose has good thermal stability within a certain temperature range and can be used in high temperature resistant applications.
Chemical Properties:
Chemical reactions: Methylcellulose can undergo chemical reactions such as esterification and etherification under certain conditions, thereby changing its properties and uses.
Hydrophilicity: Methylcellulose has certain hydrophilicity and is miscible with water and other polar solvents.
In general, methylcellulose is a multifunctional polymer with good solubility, thermal stability and chemical reactivity, so it is widely used in medicine, food, chemical industry and other fields.
