SAP Chemistry 101

The first patent for SAP was issued in 1962 to the US Dept of Agriculture for use as water conservation in soil. The product used starch as the basis for the polymer and then grafted acrylamide and acrylonitrile monomers along the chain with crosslinking agents. Starch is made of repeating units of the sugar, glucose, and there are a lot of places to add things and to crosslink these polymer chains so they become and absorbent. Click to read more!

Cost Savings with WASTE LOCK®

The use of M2 Polymer Waste Lock, saves people from spending a lot on absorbing polymer. Learn more about the cost savings!

SAP Formula

Water molecules are drawn into the network across a diffusion gradient – formed by the Sodium neutralization of the polymer backbone. Read More. 

Cross-Linking Agents used in Super Absorbents

Chains of polyacrylate and/or polyacrylamide (or in the past, polyacrylonitrile) are converted into water-swellable hydrogels through the addition of small, multi-functional monomers.  Read More.

Economic Advantages of SAP over Conventional Sorbents

The use of a superabsorbent polymer, such as Waste Lock® 770, in radioactive waste management is a cost effective way to stabilize liquid waste without significantly increasing the waste volume or weight. Click to read more!

History of SAP Chemistry Development

Until the 1980’s, water absorbing materials were cellulosic or fiber-based products. Choices were tissue paper, cotton, sponge, and fluff pulp. The water retention capacity of these types of materials is only 20 times their weight – at most. Click to Read More!

The Effect of Cations & Conductivity on Super Absorbency

In dealing with waste stabilization applications, people always ask “How much Waste Lock® do we need?”  The answer depends on the amount of cations (i.e. saltiness) of the waste liquid.   Cations increase the ability of water to conduct and electrical current.  Hence, use of CONDUCTIVITY (and a Conductivity Meter) can give a good idea of the saltiness of a waste stream. Click to read more and to see our demo video!
