ZHENGDA®

ZHENGDA® ZD-123 is characterized by repeating oxypropylene units in the backbone. ZHENGDA® ZD-123 Amine-terminated Polyether is a difunctional, primary amine with an average molecular weight of about 230. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain.

ZHENGDA® ZED-901 is an aliphatic polyether diamine derived from a propylene oxidecapped polyethylene glycol. It is water soluble, with an approximate molecular weight of 900 and a melting point around room temperature. Polyetheramines 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 polyetheramines.

ZHENGDA® ZD-1200 is characterized by repeating oxypropylene units in the backbone. ZHENGDA ZD-1200 Amine-terminated Polyether is a difunctional, primary amine with average molecular weight of about 2000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.

ZHENGDA® ZM-1100 is a polyether monoamine of approximately 1000 molecular weight. With a PO/EO ratio of about 3/19, it is relatively hydrophilic. It is a white waxy solid at room temperature.

ZHENGDA® ZM-1207 is a monoamine based on a copolymer backbone. ZHENGDA® ZM-1207 polyetheramine is a monofunctional, primary amine with an average molecular weight of about 2,000. The propylene oxide/ethylene oxide (PO/EO) mol ratio is 10/31.

ZHENGDA® ZD-140 is characterized by repeating oxypropylene units in the backbone. ZHENGDA® ZD-140 Amine-terminated Polyether is a difunctional, primary amine with average molecular weight of about 430. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.

ZHENGDA® ZED-601 is an aliphatic polyether diamine derived from a propylene oxidecapped polyethylene glycol. It is a water soluble liquid, with an approximate molecular weight of 600. Polyetheramines 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 polyetheramines.

ZHENGDA® ZM-160 is a 600 molecular weight polypropylene glycol monoamine, with methoxyethyl termination at the other end. The propylene oxide/ethylene oxide (PO/EO) mol ratio is 9/1. Polyetheramines of this type are useful in a variety of polymers because of the flexibility imparted by polyether groups.

ZHENGDA® ZT-143 is characterized by repeating oxypropylene units in the backbone.ZHENGDA® ZT-143 is a trifunctional primary amine having an average molecular weight of approximately 440. Its amine groups are located on secondary carbon atoms at the ends of aliphatic polyether chains.

ZHENGDA® ZT-1500 is a trifunctional primary amine of approximately 5000 molecular weight. It is clear, almost colorless, viscous, liquid product.

ZHENGDA® ZD-1400 Polyether amine(also called Amine-terminated Polyether)is characterized by repeating oxypropylene units in the backbone. As shown by the representative structure, ZHENGDA® ZD-1400 Amine-terminated Polyether is a difunctional, primary amine with average molecular weight of about 4000. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chains.
