Description
SULFIDE polymer is a very important and unique rubber. It is a synthetic rubber characterized by sulfur-sulfur bonds in its molecular structure.
SULFIDE POLYMER does not represent a single product, but a group of products. The CAS number is therefore a classification. Since its invention, in the 1920s SULFIDE POLYMER is an indispensable material in many high-end industries, including aerospace, automotive, construction and aviation. This is due to its outstanding stability towards numerous chemicals, its outstanding oil resistance and its outstanding airtightness and weather resistance.
It is not a common solution in rubber but it can be a good one for certain harsh conditions.
Industrial production of SULFIDE polymer is centered on the condensation reaction. The classic and most common method is to combine dichloroethylene, the main monomer of organic polymer, with an aqueous sodium polysulfide solution in a dispersed aqueous system.
The sodium polysulfides used here are usually sodium tetrasulfide and sodium disulfide. These provide the key sulfur-sulfur bonds in polymer backbone. During the process of reaction, chlorine atoms will be removed in order to form long-chains polymers that are connected by sulfur.
Initial product is a rubber-like substance with high molecular mass. To meet the majority of application requirements, particularly as sealants and adhesions, it is necessary to perform further degradation and sealing procedures to convert it to a liquid SULFIDE polymer that can be cast and vulcanized at room temperature.
The degradation process is usually carried out using chemicals like sodium hydrosulfide, which breaks long chains of polymer and introduces active groups like thiol at the end.
The main chain of SULFIDE polymer is made up of saturated hydrocarbon segments, and a series sulfur-sulfur bonds. This structure is at the core of a number of unique properties.
First, its saturated hydrocarbon structure makes it resistant to ultraviolet and ozone radiation. This reduces the likelihood of degradation. The large number of sulfur-atoms in its main chain gives the polymer an extremely high degree of polarity. This makes it resistant to nonpolar solvents like fuel, diesel, and toluene.
This structure is also responsible for the odor of SULFIDE POLYMER, which has a sulfide-specific odor. It is a negative characteristic to consider during processing and usage.
Physical and Chemical Properties of SULFIDE POLYMER
Its unique combination of properties as a final vulcanized rubber makes it one of the most popular elastomers.
Fully vulcanized SULFIDE polymer exhibits good mechanical and physical properties. Although its strength is not as high as that of some high-performance silicone rubber or fluororubber, it meets the needs of sealing materials. It is a material that has excellent barrier properties, including against water vapor and oxygen. The glass transition temperature of the material is low. This allows it to maintain some elasticity even in low-temperature conditions.

The application of SULFIDE POLYMER
SULFIDE POLYMER: Applications and core areas
The unique combination of performance and SULFIDE polymer makes it a standard or the only material in many demanding fields.
Aerospace industry is SULFIDE’s oldest and most significant application area. It is used to seal aircraft fuel tanks, fuselage panel, doors, windows and rocket fuel systems.
The aircraft is protected from structural damage and corrosion under conditions of high pressure and temperature.
Construction Industry: The use of SULFIDE polymer in this industry greatly improves the performance and longevity of modern buildings. It is used primarily as a second sealant on insulating glasses.
The first seal in insulating units mainly blocks the water vapor. SULFIDE polymer, as the secondary seal, offers excellent UV resistance and low gas permeability. This seal effectively prevents the escape of inert gas and the invasion by external water vapor.
SULFIDE POLYMER can also be used to waterproof roofs and seal building curtain walls.
SULFIDE polymer is used in automobile production to seal windows, headlights and other components that need to be resistant to gasoline and diesel. Its seawater resistance allows it to be used for seams, hatches and other ship components.
Electronics and Electrical Industry – SULFIDE POLYMER is used in the packaging and sealing of certain electronic components and cable joints. It provides environmental protection.
