Ethylene Copolymers: Techno Brief

Ethylene copolymers and terpolymers are widely used in manufacturing hot-melts adhesives and sealants because of their their mechanical cohesion and adhesive properties. In this guide, you will learn all the key facts about copolymers and terpolymers (ethylene vinyl acetates & ethylene acrylic esters) for the adhesives & sealants industry : benefits, key features, application techniques and end-market usages.

Ethylene acrylates (EMA, EBA, 2EHA)

Ethylene acrylic ester copolymers can be divided into 3 product families according to the type of acrylic derivative: butyl acrylate (EBA copolymer), methyl acrylate (EMA copolymer)or 2 Ethyl Hexyl Acrylate (2HEA).

Key benefits of Ethylene acrylic ester copolymers

These qualities make them suitable for many applications: including HMA or HMPSA in packaging or disposables for example.

Acrylic ester decreases the crystallinity of the polymer, which in turn widens the operating window of the adhesive.
