Specifications

Item, Index

Appearance: White powder or granule

Free alkali: Conforming with test

Sulfates (As SO42-): ≤ 0.5%

Loss on drying: ≤ 10%

Residue on ignition: ≤ 76%

Heavy metals (As Pb): ≤ 0.002%

Arsenic (As As2O3): ≤ 0.0002%

Residue monomer: ≤ 1%

Light polymer: ≤ 5%

Usage and Precaut Dissolving method: Add the powder slowly into 40-50degrees centigrade warm water (soft water is preferable) under stirring (Please sprinkle the powder into the weighed water instead of the opposite and avoid pouring large quantities of powder at one time because that way half-hooked clots are likely be formed and difficult to be dissolved). Keep stirring the solution under same temperature for about 0.5 hour till it is evenly mixed at the concentration 0.1-0.5%. When Sodium Polyacrylate is used for producing instant noodles, the solution should be added respectively into the flour to avoid direct contact with salt water.

Packing and Handling:

Net 25kg well-sealed PE bags. Avoid direct sunshine and rain when storage and transportation
