Super Absorbent Polymer (SAP) is a polymeric material with a three-dimensional network structure. Its molecular chains contain hydrophilic groups such as hydroxyl (-OH) and carboxyl (-COOH). It is synthesized from unsaturated monomers (e.g., acrylic acid, acrylamide) through a polymerization process involving crosslinking agents and initiators, resulting in functional polymer materials. Currently, there are many market classifications such as sodium polyacrylate, potassium polyacrylate, and polyacrylamide.
According to the latest report by QYResearch titled "Global Sodium Polyacrylate Super Absorbent Polymer Market Report 2024–2030," the global sodium polyacrylate super absorbent polymer market is expected to reach $8.7 billion by 2030. In terms of product application, baby diapers are currently the main source of demand, accounting for about 71.9% of the market share.
Main Driving Factors
Disposable hygiene products such as diapers, feminine hygiene products, and adult incontinence products are the primary users of SAP. With the growth of the global population, the demand for these products is increasing, thereby driving the growth of the Super Absorbent Polymer （SAP） market.
Women increasingly need thinner and more comfortable hygiene products that offer maximum protection and absorption. This has led to the development of SAP, which has faster absorption rates and higher retention capacities, enabling the production of thinner, more comfortable, yet highly effective products.
Industry Development Opportunities
The personal care industry is one of the largest consumers of Super Absorbent Polymer SAP, with products including diapers, feminine hygiene products, and adult incontinence products. As the population grows and disposable income increases, the demand for these products is expected to rise in the coming years, driving the growth of the SAP industry.
Super absorbent polymer for agriculture is used to retain moisture and nutrients in the soil, enhance crop yields, and reduce irrigation needs. As the global population increases and the need for more food production rises, the demand for super absorbent polymer for agriculture is expected to grow. However, attention needs to be paid to its environmental and economic sustainability. In the early stages of industry development, polyacrylamide and sodium polyacrylate were often used as water-retaining agents. As the industry and products evolved, agriculture gradually began using potassium polyacrylate containing potassium elements as the primary product for the consideration of environmentally friendly.
The molecules contain highly hydrophilic groups such as carboxyl and hydroxyl groups. When in contact with water, the polymer molecules quickly form hydrogen bonds or other chemical bonds, giving them a certain adsorption capacity for water and other strong polar substances.
The polymers are usually cross-linked and insoluble in solvents. After absorbing water, they can swell rapidly. Since the water is encapsulated in the gel-like molecular network, it is not easily lost or volatilized.
The polymers should have a certain stereostructure and high molecular weight, allowing them to maintain mechanical strength after water absorption.
Super absorbent polymers are highly useful due to their strong liquid retention, non-toxicity, non-irritability, and compatibility with skin. They also have minimal environmental impact, making them suitable for various applications across medical and hygiene products, industry, agriculture, and construction. Medical and hygiene applications include ice packs, urine bags, and negative pressure drainage bags. Industrial applications comprise water-soluble coatings, coagulants, and thickeners. In agriculture, they are used as vegetable preservation materials, water-retaining agents, and soil improvers.
SAP has excellent performance in water absorption, retention, and fertilizer preservation, making it crucial for agricultural production. In drought-prone environments, it can be used as a water-retaining agent to treat soil, significantly improving water usage efficiency and achieving maximum economic benefits. SAP can absorb large amounts of water during periods of abundance, slowly releasing it during droughts, effectively conserving rainwater, reducing irrigation frequency, and saving irrigation costs. SAP can also improve soil structure, forming aggregates that stabilize soil structure, improve soil permeability, and significantly reduce soil evaporation. Additionally, SAP enhances soil erosion resistance. As SAP can absorb and retain water and fertilizers, it is often used to encapsulate or complex fertilizers, allowing for slow release. This method not only increases crop yield under the same water and fertilizer conditions but also improves fertilizer utilization efficiency.
Application of Super Absorbent Polymers in Industrial Materials
In industrial processes, SAP plays an important role in moisture control. In the construction industry, adding water-retaining agents to cement allows it to absorb and store large amounts of water, which can be slowly released to ensure the required moisture for cement hydration. In the cosmetics industry, SAP prevents water-soluble gels from losing lubricity in dry environments, and it also has lubricating and moisturizing effects on oily substances.
Other Applications
In everyday hygiene products, SAP can be used in common sanitary products such as sanitary napkins and diapers, greatly enhancing convenience in people's lives. It can also be used in deodorizers and fragrance retention products. For example, in making solid air fresheners, a mixture of SAP and glycerin can be solidified and then added with a certain amount of fragrance, resulting in a high-performance solid air freshener.
