EAA is ethylene acrylic acid copolymer, Is a kind of thermoplastic and Highly adhesive polymer. The product has excellent adhesion, toughness, Flexibility and ease of processing, Widely used in packaging, powder coatings, Adhesives, hot melt adhesives, sealing materials, Water-based solvents, environmentally degradable materials and other fields.
It is worth noting that Among the parameters of different grades of EAA, MI value and AA content on the performance of EAA Has a great impact. When the MI is the same, as the content of AA increases, EAA's transparency, toughness, adhesion, Resistance to environmental stress cracking will increase; And its rigidity, moisture vapor transmission rate, Creep resistance and chemical resistance will be better.
When the content of AA is the same, with the increase of MI, The adhesion and processability of EAA will be better; And its toughness and environmental stress cracking resistance will increase.
