Superabsorbent polymer, often known as SAP or superabsorbent material (SAM),  High water-absorbent resin finds diverse applications in both consumer and industrial sectors due to its remarkable ability to absorb water and aqueous solutions, absorbing up to 500 times its weight in liquid. Originally developed in the 1960s by the US Department of Agriculture to enhance water conservation in soil, the initial polymer was starch-based, but modern SAP technology shifted to hydrocarbon-derived polymers, High molecular weight water-absorbent material specifically crosslinked acrylic polymers neutralized with sodium.

Superabsorbent polymers have become a staple in the hygiene industry, with around 3 million tons produced annually. Their applications include Hydrogel, Feminine hygiene pads, Fake snow, Wastewater treatment SAP, Agricultural application SAP, Baby and adult diapers, and various incontinence products.

고흡수성 폴리머의 화학: Superabsorbent polymers used in laminates and airlaids are typically formed through the reaction of acrylic acid monomer with sodium hydroxide and a cross-linking agent, resulting in polyacrylic acid sodium salt. Gel Polymerization is the most common technique, where components are sprayed onto a moving belt in the presence of UV light, causing crosslinking. Suspension Polymerization and Solution Polymerization are alternative methods.

고흡수성 폴리머 적용: 이러한 폴리머는 소변이나 혈액과 같은 수성 액체와 접촉하면 삼투 작용을 통해 수분을 흡수합니다. 따라서 압력 하에서도 많은 양의 액체를 보유할 수 있어 개인 위생 및 요실금 제품에 이상적입니다. 하지만 염분 함량이 높은 액체와 접촉하면 흡수력이 감소합니다.

고흡수성 폴리머의 중요한 특성:

• 입자 크기
• 자유 팽창 흡수 능력
• 부하 시 흡수 용량
• 수분 유지 특성
• 수분 흡수율
• 폴리머 투과성
• 젤 강도
• 위킹 기능
