ROKAmer PP4000 is a polyol (polyoxypropylene diol) with an average molar mass of about 4000 g/mol. The product is a polymer with a double-action structure, which is caused by the presence of two hydrophilic groups in the molecule. This attribute distinguishes the group of ROKAmers from other non-ionic surfactants, and determines their properties. ROKAmer PP4000 can therefore be classified as a product with anti-foaming properties, dedicated mainly to industrial processes.
The product contains approximately 100% of the active substance. It is a clear viscous liquid at room temperature, and has a low freezing point (below -20°C). It dissolves in cold water, and its solubility decreases significantly with increasing temperature. Just as all polypropylene glycols, ROKAmer PP4000 can be mixed in any proportions with organic solids and liquids, with long chain aliphatic hydrocarbons being the main exception. Additional distinguishing features of this product are excellent lubricity and low vapour pressure. In extreme heating conditions, it does not form coke or varnish, and the decomposition products have a low boiling point.
The product is used in a wide range of applications, primarily as a defoaming ingredient. It can be used as a foam reducing agent in the paper industry, in food processing (sugar production), in emulsion paints, or fermentation vats. Other uses of this product include its use as a cosmetic ingredient or as an ingredient in printing inks. In addition, ROKAmer PP4000 can be used as a lubricant base, and its very good intrinsic lubricity can be further improved by using additives.
