Polymer binder technologies are essential for the creation of new materials with distinctive physical properties through uniformly dispersing different types of materials, which do not easily dissolve with polymer, at the microscopic level. Examples of these technologies include dispersion of powdered wood into plastics and magnetic tape binder technology.

Building materials with water-proofing properties and that have the appearance of wood are produced by adding powdered wood to vinyl chloride resin. This product is used for house interiors and woody materials used around watering equipment. Zeon's technology successfully limits the loss of strength that commonly results when adding powdered wood while producing wood-like surfaces through improved extrusion technology. In addition, by adding powdered wood to polypropylene resin, acquired materials are used for park benches and materials used around watering equipment.

In addition, Zeon possesses magnetic tape binder technology featuring inorganic powder with high dispersability and excellent heat stability. This technology is widely used as binders for coated magnetic recording media, such as video tapes, tapes for computer data, floppy disks and magnetic cards.

Binder resin in coated magnetic recording media represents a key technology because it achieves high record density, durability and excellent reliability. The success of Zeon's magnetic tape binder technology follows from a thorough study of the base polymer and the functional group to be used in order to attain these desired properties. The dramatically improved magnetic powder dispersibility of this product resulted from the development of a method for introducing a strong acid base into vinyl chloride resin, which had been considered difficult using conventional approaches. Furthermore, the technology development achieved landmark heat stability for PVC through a unique method of polymerization. By virtue of its contribution to improved metal tape recording density and reliability, the technology has been rapidly adopted for a growing range of applications around the world.
