Poly(2-ethylhexyl acrylate)

polymer

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.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
