Liquid Polysulfide Polymer - Global Industry Market Analysis Report 2020-2031

Liquid polysulfide polymers are specialty elastomers, which are a class of polymers with sulfur atoms in the molecular main chain and highly reactive terminal groups. In their molecular structure, sulfur atoms endow the polymers with unique properties. These polymers usually exhibit different viscosities ranging from low to high, and are commonly seen as brown viscous liquids.

The synthesis of liquid polysulfide polymers mainly uses bis(2 - chloroethyl) formal (diform) and sodium polysulfide (Na₂Sₓ, x = 2.4 - 2.6) as the main monomers. During the polymerization process, 1,2,3 - trichloropropane (TCP) is often added to regulate the degree of branching of the polymer main chain. The polymerization reaction is carried out in an environmentally friendly water - based dispersion system through emulsion polymerization. The initially formed polymer has a high molecular weight. Subsequently, reductive splitting agents such as Na₂SO₃, Na₂S₂O₄, and NaSH are used to chemically reduce the high - molecular - weight solid polysulfide polymer latex to obtain a liquid polysulfide polymer with the target molecular weight, chain length, and adjust its thiol (SH) content. The molecular weight range is approximately between 1000 - 7000 g/mol, and products with different molecular weights have different application scenarios.

This polymer has many excellent properties. It has excellent chemical stability, showing high resistance to most organic solvents, oils, fuels, and alkalis, and can maintain its structure and performance stability in harsh chemical environments. It has outstanding high and low - temperature resistance, remaining flexible at low temperatures and can withstand low - temperature environments down to about - 55 °C, and is not prone to performance degradation in high - temperature environments. Its electrical properties are excellent, with extremely low permeability to many gases and moisture, effectively blocking the intrusion of external substances. In addition, it also has good adhesion properties, can firmly adhere to the surface of a variety of materials, and has flex - crack resistance, and is not prone to cracking when subjected to repeated bending and other stress.

In terms of preparation, reaction conditions such as temperature, pressure, monomer ratio, and reaction time need to be precisely controlled to ensure the production of liquid polysulfide polymers with specific properties. Advanced preparation processes are moving towards the direction of improving production efficiency, reducing energy consumption, and enhancing product quality uniformity.

In the market application field, it is widely used. In construction, it is often used to manufacture sealants, such as the sealing of building doors, windows, curtain walls, and the expansion joints of road surfaces. With its excellent weather resistance, water resistance, and adhesion, it effectively prevents the intrusion of external moisture, gases, etc., and extends the service life of building structures. In the aerospace field, it is used for the sealing of aircraft fuel tanks and fuselages, ensuring the safe and reliable operation of the fuel system, preventing fuel leakage, and meeting the high - performance requirements of materials for aerospace equipment in extreme environments. In the automotive industry, it can be used for the sealing, shock absorption of automotive bodies, and the bonding of automotive glass, etc., improving the overall performance and sealing of automobiles. In the marine engineering aspect, it plays an important role in the waterproof and anti - corrosion sealing of offshore platforms, ships, and other facilities, resisting the erosion of seawater and the influence of harsh marine environments.

From the perspective of market development trends, with the continuous growth of the demand for high - performance materials in various industries around the world, the market for liquid polysulfide polymers has broad prospects. The demand for green, environmentally friendly, and high - performance sealing materials in the construction industry has prompted enterprises to develop more environmentally friendly and higher - performance products. The development of high - end manufacturing industries such as aerospace and automobiles has put forward higher requirements for the comprehensive performance of materials, promoting enterprises to increase R & D investment, improve preparation processes, and enhance product quality and performance stability. At the same time, market competition is also becoming increasingly fierce. Enterprises are vying for market share through technological innovation, optimizing product structures, and reducing costs. In addition, with the acceleration of infrastructure construction in emerging market countries and the continuous development of the industrial manufacturing industry, the demand for liquid polysulfide polymers is expected to further increase.
