The flake form of SINTEPEG 2400 is packaged in big bags with polyethylene liner with a net weight of 750 kg; An aqueous solution of SINTEPEG 2400/60 is poured into:
- polyethylene barrels with a capacity of 227 liters;
- IBC containers, 1000 liters;
The warranty period for the SINTEPEG 2400 is 1 year from the date of manufacture.
To prevent polymerization and clumping, the SINTEPEG 2400 macromonomer is recommended to be stored at a temperature not higher than + 30 ° C. The lower limit of temperature is not specified. To prevent crystal formation and polymerization, SINTEPEG 2400/60 macromonomer should be stored at a temperature of 10 to 30 ° C. As a result of long-term storage at lower temperatures, precipitation may occur in the SINTEPEG 2400/60. The product does not lose its quality, but before use it is need to be heated to a temperature of 20-30 ° C and homogenized.
