Polyethylenimine (PEI) is a polymer with repeating unit composed of the amine group and two carbon aliphatic CH2CH2 spacer. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. Totally branched, dendrimeric forms were also reported. PEI is produced on industrial scale and finds many applications usually derived from its polycationic character.
Global Polyethylene Imine key players include BASF, NIPPON SHOKUBAI, etc. Global top two players hold a share about 95%.
North America is the largest market, with a share about 35%, followed by Europe and China, having a total share about 50 percent.
In terms of product, Assay: Under 50% or 50% is the largest segment, with a share about 60%. And in terms of application, the largest application is Paper-making Industry, followed by Electroplating Industry, Biomedicine Industry, Coating Industry, Water Treatment Industry, etc.
