With the increasingly stringent environmental protection policies and the acceptance of energy saving and emission reduction concepts, the development of the waterborne polyurethane industry has accelerated, driving the release of the demand for hydrophilic polyurethane chain extenders
.
Polyurethane is a multifunctional and versatile synthetic polymer material.
It is usually prepared by the reaction of oligomer polyols, polyisocyanates, chain extenders and crosslinking agents.
The function of the chain extenders is to spread and extend the molecular chain.
Realize the curing and molding of resin
.
As an important raw material for the hard segment of the polyurethane molecule, chain extenders endow polyurethane materials with good strength, wear resistance and heat resistance.
Polyurethane chain extenders are usually small molecular compounds containing hydroxyl or amino groups, mainly including aliphatic Diols, aromatic diols, aromatic diamines, etc.
, among which aromatic diamine chain extenders are the mainstream products in the polyurethane chain extender market
.
According to the "In-depth Evaluation of China's Polyurethane Chain Extender Industry Market and Investment Feasibility Consultation Report for 2021-2025" issued by the New Sijie Industry Research Center, China is a big country in the production and consumption of polyurethane in the world, and the total domestic polyurethane production capacity accounts for approximately the global total production capacity.
In 2020, the output of China's polyurethane industry will be around 14.
7 million tons
.
Polyurethane chain extender is an indispensable and important raw material in the process of polyurethane synthesis.
In recent years, as the output of the polyurethane industry continues to grow, the market demand for polyurethane chain extenders continues to increase
.
Polyurethane chain extenders belong to a technology-intensive industry.
There are certain technology, R&D, talent, and production barriers in the industry, so the industry has a high barrier to entry
.
Compared with developed countries such as Europe and the United States, China's polyurethane chain extender industry started late.
In the early days, China's polyurethane chain extender market was mainly monopolized by foreign-funded enterprises.
In recent years, with the increase of national support and the strengthening of domestic enterprises' R&D capabilities, China's polyurethane chain extender enterprises have made certain achievements in production technology and product quality, and successfully broke the pattern of foreign technology monopoly.
At present, China has become the world's largest polyurethane chain extender producer and consumer
.
With the continuous deepening of research and the continuous advancement of science and technology, more and more new chain extenders are applied to the production of polyurethane, such as MCDEA, E-100, HER, HQEE and other products, including liquid type with independent intellectual property rights.
HQEE and HER have achieved industrial production
.
With the increasingly stringent environmental protection policies and the acceptance of energy saving and emission reduction concepts, the development of the waterborne polyurethane industry has accelerated, driving the release of the demand for hydrophilic polyurethane chain extenders
.
On the whole, China's polyurethane chain extender industry will continue to upgrade in the direction of environmental protection, energy saving, high efficiency, diversification and safety in the future
.
Industry analysts in Xinsijie said that polyurethane chain extenders are indispensable and important raw materials in the polyurethane synthesis process.
In recent years, as the output of the polyurethane industry continues to increase, the market demand for polyurethane chain extenders has gradually released
.
With the continuous deepening of research and the upgrading of market demand, more and more new chain extenders are applied to the production of polyurethane.
The types of polyurethane chain extenders are gradually enriched.
The future development prospects of China's polyurethane chain extenders industry are better
