Amine Initiated Polyether Polyol is a polyether polyol made by reacting amine compounds as initiators with epoxides.Its characteristic is that it initiates the reaction through amines, and forms a polyether structure with special functional groups during the polymerization process.
This reaction usually involves low molecular weight compounds containing active hydrogen, such as amines, as initiators, which react with compounds containing epoxy structures under the action of catalysts to undergo ring-opening polymerization.
Features of Amine Initiated Polyether Polyol
Due to the introduction of amine groups, Amine Initiated Polyether Polyols usually have higher chemical stability and are more resistant to moisture, heat and other chemicals.
Amine-initiated polyether polyols have higher activity, so they can react more easily with isocyanates during the production process to produce high-quality polyurethane foams.
Compared with conventional polyether polyols, amine-initiated polyether polyols usually have better high temperature resistance and can maintain their physical properties for a long time under high temperature conditions.
Such polyether polyols can provide stronger strength and toughness in polyurethane foams, and enhance the compression and impact resistance of foams.
Due to their special chemical structure, amine-initiated polyether polyols usually exhibit lower odor and volatility, which meets modern environmental protection requirements.
By adjusting the type of amine initiator and polymerization conditions, polyether polyols with different molecular weights, hardness and functions can be produced to meet the needs of different industrial applications.
Advantage of Amine Initiated Polyether Polyol
The advantages of amine-initiated polyether polyols mainly include the following aspects:
High reactivity: Polyether polyols with amine as initiator have self-catalytic effect and high reactivity, which can reduce the amount of amine catalyst.
Fast curing speed: Polyether polyols with aromatic diamine as initiator can cure quickly and produce high-strength foam with low thermal conductivity.
Wide application: Polyether polyols with amine as initiator are widely used in rigid foam formulations, can produce sufficient crosslinking degree and rigidity, and are suitable for various occasions requiring high strength and good thermal conductivity.
