Notes:
- Weight percentage norms of impurities are given in equivalent 100% product.
- For the production of high purity ion-exchange resins sodium chloride weight percentage in cleared pyretic natron shall not exceed 0,005%.
- For the chemical fibers and non-food cellulose film production potassium weight percentage is not more than 0,03% in both grades.
Shipped as a solution (colourless transparent fluidal), in railway tank cars of 60 tons (28-30 tons in equivalent100%base material).
