Sodium Polyacrylate (SPA)
Sodium Polyacrylate(SPA) can be used for low-salt animal skin preservation.
It is a functional polymer with good water absorption and water holding capacity.
We can use sodium polyacrylate absorbing, retaining or to block liquid–it can absorb water up to several hundred times of its own weight and turn into natural gel from within seconds.
Other side, it is Non-toxic, Harmless and Nonpolluting.
What is Sodium Polyacrylate?
It is a functional polymer with good water absorption and water holding capacity.
We can use sodium polyacrylate absorbing, retaining or to block liquid–it can absorb water up to several hundred times of its own weight and turn into natural gel from within seconds.
Other side, it is Non-toxic, Harmless and Nonpolluting!
How it works?
It consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network.
When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored.
Applications
Agricultural Grade Applications
Widely used in agriculture, forestry and gardening, such as soil water retention agent, seed coating, soil-less cultivation, artificial turf, etc.
–Advantages:
-Improve seed germination and give plants an early, health start.
-Save the irrigation,increase crops and fruit yield.
-Release the fertilizer efficiency slowly.
Hygienic Grade Applications
Mainly used in Hygiene Products such as Diapers, Sanitary Napkins, Nursing Pad and Pet Pad ect.
Good Performance In :
-Absorption Rate
-Absorption Under Pressure
-Retention Capacity After Centrifugation
Industrial Grade Applications
Industrial grade SAP can be mainly used in sandbag, protection material of concre,waterproof tape and waterproof ointment for using in optical fiber cables and so on.
Other Applications:
