    Sodium polyacrylate

    Sodium polyacrylate is a new-function material with good water-absorbing capacity. It is non-toxic, harmless, and nonpolluting.


    What can it do?

    Absorb lots of water or other liquid.   (applications: paper diaper, sanitary napkin.)

    After absorbing, turn to water gel which can return water back to the plant.  (applications: water-retaining gel for plants.)

    After absorbing, turn to water gel which can lock liquid strongly.  (applications: water-blocking material in  anti-flood bag, waterproof tape in cables, and so on.)

    Mainly Applications

    We can use sodium polyacrylate to absorb, retain, or block liquid. Here are some of the applications as follows.

    Hygiene Product Applications (as absorption material)

    Sodium Polyacrylate is widely used in hygiene products such as paper diapers, sanitary towels, pets pads,s and so on.

    For Paper Diapers

    SAP for diapers has good permeability, strong absorptive capacity, and maintenance ability. It will not happen to return the infiltration phenomenon under a certain pressure.

    For Lady Sanitary Napkin

    SAP for sanitary napkins has fast suction of blood, high absorption capacity, good gel strength, and moisture resistance. The strong absorption capacity and water retention ability in women`s sanitary napkins can keep dry and comfortable.

    Other Sodium Polyacrylate Applications

    For Cables

    Used in waterproof tape and waterproof ointment for use in optical fiber cables.

    The absorbency and reaction are quick and the overall inflation rate and inflation extent are good when meeting water.

    For Ice Bag

    The single sheets of Ice packs are activated by placing them in fresh tap water. The super absorbent polymer will take up the water instantly, within 20 minutes it has taken up enough water to form cushion shape ice cubes. Then you can place it into the freezer before use.

    For Anti-flood Bag

    SAP in an anti-flood bag absorbs the water completely in 3 to 5 minutes when meets water and the bag will inflate quickly. Before absorbing water, the bag is small and light. It is very easy to store and transport. Also, it not needs more storage space than traditional sandbags.

    For Concrete

    -Permeability concrete.
    -It with fibrous shapes that potentially can be used to make high.
    -Can be used as an internal sealant in cement-based materials.
    -A particular use of SAP Polymer in concrete could be as a controlled release agent.
