ED-900 Polyether Amine

Chenhua ED-900 Polyether amine is an aliphatic polyether diamine derived from a propylene oxide-capped polyethylene glycol. It is water soluble, with an approximate molecular weight of 900 and a melting point around room temperature. Polyether amines of this type are useful in a variety of polymers because of the hydrophilicity and flexibility imparted by the polyethylene glycol chain. In polyamides, for example, antistatic properties and moisture vapor transmission can be enhanced by incorporation of PEG-based polyether amines.
