poly(ethylene-co-acrylic acid)
polymerPoly(ethylene-co-acrylic acid), or EAA, is a copolymer combining the backbone of polyethylene with randomly distributed acrylic acid units, creating a material with tunable polarity and adhesion characteristics. It is widely used in adhesives, coatings, and films for packaging applications where bonding to polar substrates or improved moisture barrier properties are required. EAA is valued over homopolymer polyethylene because the acrylic acid groups enable stronger adhesion to metals, ceramics, and other substrates, making it an economical choice for flexible multilayer constructions and hot-melt adhesive formulations.

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.
