How are the Mowital® grades labeled?
The properties of Mowital® grades are mainly influenced by the molecular weight and the degree of acetalization. The Mowital® range is labelled by a special code of letters and numbers. The numeric suffixes 20, 30, 45, 60, etc. refer to increasing molecular weight, resulting in increasing viscosity of solutions. The letters T, H and HH refer to increasing degree of acetalization. In detail: T means low, H means intermediate and HH means high degree of acetalization. Increasing degree of acetalization corresponds to decreasing amount of residual OH-groups and decreasing polarity.
