Polüetüülakrülaat

Polüetüülakrülaat, also known by its chemical abbreviation PEA, is a synthetic polymer derived from the monomer ethyl acrylate. It belongs to the family of acrylic polymers and is known for its flexibility, clarity, and good adhesion properties. PEA is a thermoplastic material, meaning it softens when heated and solidifies when cooled.

The polymerization process for ethyl acrylate typically involves free-radical polymerization, often initiated by peroxides or azo compounds. The resulting polymer chain consists of repeating ethyl acrylate units. The physical and chemical properties of PEA can be influenced by factors such as molecular weight, degree of branching, and the presence of any comonomers.

Polüetüülakrülaat finds applications in various industries due to its desirable characteristics. It is commonly used as a binder in paints and coatings, providing adhesion and flexibility. In the adhesives industry, PEA serves as a component in pressure-sensitive adhesives, offering tack and peel strength. It can also be found in textile finishing, paper coatings, and as a plasticizer in other polymer formulations. Its resistance to water and many chemicals makes it suitable for use in environments where durability is important.
