Super absorbent polymer (SAP) is a high-performance, non-toxic network polymer. Thanks to its exceptional water-absorbing and water-retention capabilities, it has found wide-ranging applications across agriculture, healthcare, general industry and environmental protection, emerging as a highly valuable functional material for advances in modern science, technology and industrial development.

Water-swellable rubber (WSR) is a high-performance composite sealing and waterproofing material. It is produced using a rubber matrix featuring high resilience, elasticity, toughness and tensile properties, which is further compounded and modified with water-absorbing polymer components.

Across global cold-chain logistics, medical transport and food preservation sectors, high-quality ice packs form the backbone of integrated temperature-control solutions and underpin enterprises’ product competitiveness. Balancing stable performance, safety, environmental friendliness and cost-efficiency remains a key challenge for ice-pack manufacturers.

Water plays a vital role over the entire life cycle of concrete. It is an indispensable constituent for mixing, curing and hardening. Nevertheless, moisture exchange between hardened concrete and the external environment may trigger its shrinkage-expansion behaviour, resulting in cracking defects that directly impair structural service durability.

Agricultural water-retaining agents represent adaptive chemical water-saving materials for farmland conservation in China. Functionally, they are super absorbent polymers (SAPs), also termed water absorbents or water-holding agents. These moderately cross-linked, water-swellable polymeric materials carry abundant hydrophilic groups such as carboxyl and hydroxyl groups.
