The composition of a mixture is determined via the so-called mixing ratio. It indicates how many parts or % by weight of two or more components are mixed. The mixing ratio is mandatory and can only be achieved by an exact weighing with a digital scale.
Different mixing ratios, for example in polyurethane foams, have a significant influence on the properties of the final product.
