D-2000 Polyether Amine
Structure:
NH2CH (CH3)CH2 [OCH2CH(CH3)]X NH2 X=33.1
Description:
Chenhua D-2000 polyetheramine is a member of a family of polyamines having repeat oxypropylene units in the backbone. It is a difunctional primary amine with an average molecular weight of about 2000. Its amine groups are located on secondary carbon atoms at the ends of an aliphatic polyether chain. It is light in color and low in viscosity. Its vapor pressure is extremely low. Chenhua D-2000 polyetheramine is completely miscible in a wide variety of solvents. It is, however, only slightly soluble in water.

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.

EH Special Surfactants Instructions
EH Special surfactant won the industry's broad attention by its high performance, low toxicity, and the biodegradable characteristics, it not only can improve household detergents cleaning performance, but also easy to biodegradation, aquatic toxic (EC50) is more than 10 mg/l. There is not any alkyl phenolic component in products, and can replace NP series surfactants, while strengthening the product biodegradable properties, make its lowest influence to environment.
EH special surfactant is with good wetting emulsification performance, which can improve the cleaning ability of cleaner, at the same time reduce the demand of the solvent in formula; with light odor, it can reduce stimulating in formula, and enhance the effect of spice; with a low foam characteristics, it is easy to rinse, and fasten the dissolve time, with gel narrow range, it can shorten the formula time, especially for the preparation of concentrated prescription, it could reduce packing and the use of water.
