Our polymer is made from a range of different PVOH blends, formulated using proprietary process which can be designed to be soluble in water at controllable temperatures.  The temperature at which our polymer dissolves in water can be varied by the type of PVOH used, the thickness and surface area of the product, the temperature, agitation and the amount of water present.  Hot water soluble grades, are more robust at cold temperatures, but dissolve rapidly at temperatures above 70℃. The water solubility is an important feature for the end of life as it causes the product to soften and break-down in the environment. This can increase the speed at which the material will biodegrade into mineralised biomass, CO2 and water.  Warm water soluble grades will break-down rapidly at temperatures above 20℃.
