The adhesive of protective film / tape is made of natural materials or synthetic polymers.
Acrylic adhesive is a typical synthetic adhesive.
Acrylic adhesive raw materials:
The raw materials used in the acrylic adhesive are acrylic monomers, which are also used in contact lenses, plastic glass and water-absorbing polymers.
By selecting and polymerizing these acrylic monomers, acrylic polymers having certain functions can be synthesized and used as a protective film/tape adhesive.
Acrylic adhesives are widely used in the manufacture of LCD panels, cell phones and automobiles due to their excellent transparency, weather resistance, heat resistance and chemical resistance.
Synthesis of acrylic adhesives:
There are three methods for synthesizing an acrylic polymer: solution polymerization, emulsion polymerization, and UV polymerization.
In recent years, as global environmental awareness has increased, methods of emulsion polymerization and UV polymerization have become more and more popular because the two synthetic methods do not require the use of organic solvents.
The various methods of synthesizing acrylic polymers and their corresponding advantages and disadvantages are shown below.
A. Solution polymerization
B. Emulsion polymerization
