InChem Corp. (Rock Hill, S.C., USA) will emphasize in its booth new applications for its line of phenoxy resins. Phenoxy resins are tough, clear and flexible thermoplastic chemicals with high cohesive strength and good impact resistance, designed to enhance the performance of coatings, inks, composites, adhesives, carbon fibers and other products. InChem says recent application research has found that phenoxy resins can be highly effective when used in composite pre-pregs, carbon nanotubes and other advanced composite applications. Phenoxy resins are distinguished by three main characteristics:
- Clear - haze values typically <5
- Tough - tensile strength 9000 to 9500 psi
- Flexible - tensile elongation 50 to 100 percent
Phenoxy resins are available as pellets, waterborne solutions, solvent solutions and film. Company officials note that because of its long hydroxyl backbone, phenoxy crosslinks with a variety of chemicals, resulting in a new hybrid product that has the characteristics of both. It can thus add strength, toughness and impact resistance to many other chemical products.
