설명

애플리케이션

Polyethylene glycol 1500 can be used as:

• A plasticizer in the synthesis of polylactic acid/talc composites to improve the crystallinity and mechanical properties of the material.
• A non-ionic surfactant in the preparation of organoclays.
• A reactant in the synthesis of quasi-prepolymers by reacting with a polymeric 4,4′-diphenylmethano diisocyanate (pMDI) via the pre-polymerization method.

PEG-1500 can also be used in the aqueous two-phase extraction system along with inorganic salts (sulfates, carbonates, and ammonium phosphates) for the separation and extraction of both organic (amino acids and vitamins) and inorganic substances (metal salts).
