Polyvinyl alcohol hydrogel (PVA hydrogel) is a class of three-dimensional network gel materials formed from polyvinyl alcohol via physical or chemical crosslinking. PVA is a water-soluble, biocompatible synthetic polymer containing abundant hydroxyl functional groups, which can crosslink to form hydrogels. Thanks to this unique structure, the mechanical properties of PVA can be further enhanced while maintaining excellent biocompatibility. As a result, high-strength and high-toughness PVA hydrogels have attracted widespread attention in medical devices, tissue engineering, drug delivery, sensors, biomimetic materials, food packaging, and industrial functional materials. BOC Sciences provides multi-type PVA hydrogel preparation and development services, covering PVA-PEG, PVA-Alginate, PVA-Chitosan, PVA-Gelatin, and nanocomposite hydrogel systems. With advanced techniques in physical crosslinking, chemical crosslinking, interpenetrating network, and double-network construction, we can precisely tailor gel mechanics, porosity, swelling behavior, and functional responsiveness. Through professional formulation design, composite material development, and performance optimization, BOC Sciences offers highly customized hydrogel solutions for tissue engineering, drug delivery, biomimetic materials, and flexible functional materials, meeting diverse research and application needs.

Polyvinyl alcohol (PVA) itself is a water-soluble polymer, not a hydrogel in its native form. However, when PVA chains are physically or chemically crosslinked, they form a three-dimensional network capable of absorbing large amounts of water, which is defined as a hydrogel. PVA hydrogels exhibit biocompatibility, mechanical flexibility, and tunable swelling properties suitable for biomedical applications.
PVA hydrogels can be prepared through physical or chemical crosslinking. Physical methods include repeated freeze-thaw cycles, inducing crystallite formation between PVA chains. Chemical methods involve using crosslinkers like glutaraldehyde or borax to create covalent bonds, forming a stable network. Process parameters such as polymer concentration, temperature, and crosslinking degree influence mechanical strength, swelling behavior, and transparency.
PVA hydrogels are widely used in biomedical, pharmaceutical, and industrial fields. They serve as wound dressings, drug delivery matrices, tissue scaffolds, and contact lenses due to biocompatibility and flexibility. In industrial contexts, they function as absorbents, coatings, and membranes. Their tunable swelling, mechanical stability, and transparency make them ideal for controlled-release and tissue engineering applications.
Crosslinked PVA hydrogel is a three-dimensional polymer network formed by chemically or physically connecting PVA chains. Crosslinking restricts chain mobility, enhancing mechanical strength, water retention, and dimensional stability. This structure enables precise control over swelling, diffusion, and degradation rates. Crosslinked PVA hydrogels are widely applied in biomedical devices, drug delivery systems, tissue scaffolds, and contact lenses due to their tunable properties.
Chitosan–PVA hydrogel is a biocompatible, water-swollen polymer network formed by blending chitosan, a natural cationic polysaccharide, with polyvinyl alcohol (PVA), followed by physical or chemical crosslinking. The combination enhances mechanical strength, swelling capacity, and antimicrobial properties. These hydrogels are widely used in wound dressings, drug delivery systems, and tissue engineering scaffolds due to their biodegradability and tunable properties.
We provide diverse PVA hydrogel types, including PVA-PEG, PVA-alginate, PVA-chitosan, PVA-gelatin, and nanocomposite hydrogels. Each type supports tailored structural, mechanical, and functional properties. Our expertise enables precise control of crosslinking, porosity, and bioactivity, allowing hydrogels to be optimized for tissue engineering, drug delivery, wound care, and soft biomaterial applications.
PVA hydrogels are generally non-toxic, highly biocompatible, and suitable for medical and research use. Biocompatibility can be further enhanced by controlling crosslinking, polymer purity, and incorporating bioactive components. BOC Sciences conducts rigorous material characterization and performance testing to ensure hydrogels meet safety and application standards in tissue engineering, drug delivery, and biomedical research.
