Starch Graft Technology, 1997 Nonwovens Conference Proceedings
The technology of starch graft polymers has advanced to provide non-formaldehyde, self-crosslinking latex dispersions which have a stable rheology. These products have found uses as binders for fiberglass, polyester and cellulosic materials where high temperature performance and water resistance are required. They have also found uses as extenders and modifiers for PF and UF resins, often showing a synergistic effect. Resin binder systems containing starch graft components often show improved dry and hot wet tensile strength versus traditional emulsion polymer modifiers. This technology offers tremendous versatility in designing products for a particular need by choosing from various monomers and starch types. By matching monomer and starch to performance re-quirements, nonionic, anionic and cationic polymers can be designed for high-performance applications.
