What are Super Absorbent Polymers? Super Absorbent Polymers (SAPs) are substances that can hold a huge amount of liquid in relation to their size . These polymers are used as an absorbent of water and aqueous solutions mainly in diapers. The difficulty in screening super absorbent material comes from the particles itself. Super absorbent particles are extremely misshaped and makes it difficult for individual particles to find the screen hole openings. The other major problem with screening super absorbents is that the particles are very friable. This means that too much energy will actually break up the material and this is not a desirable outcome for companies looking to have their super absorbent material sieved.
