Chemical Structure of BPI Cellulose Polymer Products
H Series polymer products are water-soluble polymers that are derived from cellulose, the most abundant natural carbohydrate polymer on Earth. These polymers have the polymeric backbone of cellulose to which other organic groups have been attached. While the basic repeating structure of anhydroglucose units forms the largest portion of the molecule, the functional side groups give these polymers a number of unique properties. The fully processed polymer is a dry, somewhat fibrous powder. However, BPI also offers liquid products consisting of pre-dispersed suspensions of H Series polymers. All of these products are very water soluble and produce high tensile strength networks when mixed with fibers and other solids. Other properties helpful to formulators of erosion control products are described under H Series Polymers: A Unique Combination of Properties.
Because H Series products are produced from secondary sources of cellulose polymers, the degree of substitution (DS) will vary from 1.3 – 2.0. Likewise, the molar substitution (MS) may vary from 0.2-1.8. These variations do not affect the many functional characteristics useful in almost all approved erosion control applications. These properties have proven to be valuable in a variety of water-based soil stabilization applications. H Series products cannot be used in industrial applications or any other application not approved by BPI.
There are also specialized BPI products available that are based on synergistic blends of H Series polymers with other materials. They have been formulated to meet the requirements of specific end uses. These engineered products contain additives and particle size modifications custom-tailored to optimize performance in situations where equipment design and other considerations are involved.
