Shines where Polyurethanes and Silicones fail
Whether it's enhancing the longevity of insulating glass windows, protecting critical aircraft components, fortifying industrial structures with epoxy coatings and adhesives, or providing vital fire protection through intumescent coatings, Thioplast® polysulfides proves to be a versatile and indispensable asset in reinforcing the safety, longevity, and performance of critical components and structures across various industries.

Thioplast® polysulfide-based sealants in sewage plants
Thioplast® polysulfide-based sealants are utilized in sewage plants to create durable and chemically resistant seals for concrete joints, pipelines and structural components, effectively preventing water and chemical ingress and contributing to the integrity and efficiency of sewage treatment infrastructure.

The power of Thioplast® G polysulfides

The Thioplast® G polysulfides variants are medium to high-viscosity liquids with a light red-brownish color. The average molecular weight of the polysulfides determines their viscosity, making it a crucial characteristic for accurate testing. 

Properties
The key properties of thiol-terminated Thioplast® G polysulfides are elasticity and pronounced chemical resistance. These properties make them ideal as base polymers for sealants. Additionally, these polysulfides can withstand a wide range of curing conditions, and their physical properties can be easily tailored to specific application requirements.

Product Range
Nouryon currently manufactures a wide range of Thioplast® G polysulfides, each with variations in molecular weight, viscosity, and branching.
This diverse product range is designed to meet requirements for nearly all applications in the CASE segments. Additionally, Nouryon can produce tailor-made polymers based on special requests.

Thioplast® G polysulfides in window sealants
The combination of good UV stability and gas-tightness renders Thioplast® G polysulfide-based sealants one of the most resistive, long-lasting, and therefore cost-efficient sealants in the world.

Thioplast® G polysulfides

Flexibility

Accommodates movement, and strong adhesion to a wide range of materials such as metals, glass and concrete, providing reliable and long-lasting seals.

Resistance

Exceptional resistance to various chemicals including fuels, bases, and industrial solvents, making it suitable for applications in harsh chemical environments.

Durability

Remarkable weather resistance, performance and integrity in challenging conditions, even during extreme temperature variations and UV radiation.

Building and construction

Thioplast® G polysulfide-based construction sealants have a reputation for high performance, they are used to seal glass in aluminum frames, concrete moving joints, steel/stone joints, as well as many other applications.

Immersion in water for long periods or continuous exposure to high humidity are especially difficult conditions for organic-based materials to withstand.
Sealants for use in water purification or wastewater treatment plants have special demands for physical, chemical, and microbiological properties. Thioplast® G polysulfide-based sealants have proven useful in this area.

Thioplast® G liquid polysulfides are very suitable as sealants and coatings for secondary containment areas, where they prevent chemicals, solvents, fuels etc. from seeping into the ground in the event of spillage or a storage tank leak.

Thioplast® polysulfide-based sealants in gas station road sealants
Thioplast® polysulfide-based sealants offer exceptional chemical resistance, flexibility, and longevity, making them ideal for gas station road sealants.

Setting the standard for aircraft integrity
