Poly(2-ethylhexyl acrylate)

Poly(2-ethylhexyl acrylate), or PEHA, is a synthetic acrylic polymer derived from the acrylate monomer family, characterized by a flexible long-chain alkyl side group that imparts soft, rubbery properties. This material is primarily used in adhesives, sealants, and elastomeric coatings where flexibility and low-temperature performance are critical—particularly in construction, automotive, and flexible packaging applications. Engineers select PEHA-based systems when they need excellent elongation, adhesion to difficult substrates, and environmental resistance combined with cost-effectiveness; its low glass transition temperature makes it especially suitable for applications requiring performance in cold climates or dynamic mechanical stress.
