The global polyethyleneimine market size was valued at USD 1.2 billion in 2022. Polyethyleneimine (PEI) is a polymer with repeating units of aminoethylamine that is highly branched. It has numerous industrial applications including water treatment, paper manufacturing, mining, leather tanning, coatings, fabric and textiles. PEI is a cost-effective material that possesses excellent adsorption properties, which makes it suitable for removing impurities and heavy metals from wastewater. It is widely used as a flocculating and coagulating agent in water and wastewater treatment plants.

The global polyethyleneimine market is estimated to be valued at USD 1.64 billion in 2024 and is expected to exhibit a CAGR of 7.3% over the forecast period 2024.

Key Takeaways
Key players operating in the polyethyleneimine market are BASF SE, Prime Polymer Co. Ltd., SNF Group, Nippon Shokubai Co. Ltd., Yixing Danson Technology.

The growing global concern regarding water pollution and scarcity is driving the demand for effective water treatment solutions. PEI helps purify water by binding with impurities and removing them, thus boosting the treatment of industrial and municipal wastewater.

The expansion of wastewater treatment facilities, especially in developing nations is propelling the Polyethyleneimine Market Growth. Moreover, stringent environmental regulations regarding wastewater disposal are compelling industries to invest in advanced water treatment technologies that employ PEI.

Market key trends
One of the key trends witnessed in the polyethyleneimine market is its increasing adoption in enhanced oil recovery processes. PEI finds application as a thickener and fluid loss additive in drilling fluids. It helps thicken the drilling fluid and prevent fluid loss into the formation during drilling. Moreover, PEI plays a vital role in tertiary oil recovery by acting as a displacing and blocking agent. Its high charged density property enables it to effectively recover residual oil trapped inside oil reservoirs. The growing EOR activities globally will augment the demand for PEI over the forecast period.

Porter’s Analysis

Threat of new entrants: Low capital requirements and widely available raw materials allow new companies to enter the market easily.

Bargaining power of buyers: Buyers have low bargaining power due to specialized nature of the product and lack of substitutes.

Bargaining power of suppliers: Few manufacturers globally service this niche industry, allowing suppliers to influence prices.

Threat of new substitutes: Limited substitute products exist for polyethyleneimine applications in wastewater treatment, hair conditioners, and anderen.

Competitive rivalry: Intense competition exists between global leaders to exploit niche application areas.

North America accounts for the largest share of around 30% of the global polyethyleneimine market, primarily due to strong demand from wastewater treatment applications in the region. Asia Pacific is expected to grow at the fastest rate during the forecast period, supported by burgeoning demand from industries such as hair care, agriculture, mining, paper, and water treatment from major economies of China, India, and Japan.
