Hydropol polymer pellets
Hydropol is a speciality polymer resin based on polyvinyl alcohol (PVOH), which is non-toxic, biodegradable and soluble in water. A number of different formulations of Hydropol are available, depending on the requirements of the customer. The intended application of Hydropol is for further processing into a variety of plastic products, including single-layer plastic film, extrusion coatings, laminations to paper or board and injection mouldings. A key feature of Hydropol is inherent biodegradability and solubility in water. The base polymer of Hydropol, PVOH, is composed of a long carbon chain with hydroxyl (–OH) functional groups that largely determine the degree of hydrolysis, and therefore solubility of the polymer in water. Through careful control of the hydrolysis levels during manufacturing, Aquapak produce a range of Hydropol polymers with different functionalities for use and end-of-life. These Hydropol formations can biodegrade or dissolve in controlled and uncontrolled end-of-life treatment methods such as composting or anaerobic digestion and littering in ocean or soil. Aside from biodegradability and solubility in water, other important properties of Hydropol include high tensile strength, puncture resistance, resistance to oils, electrostatic dissipation and UV-resistance.
