Thioplast® polysulfides - putting a seal on 60 years

Thioplast® polysulfides, which are characterized by sulfur-sulfur bonds, were originally introduced in 1963 and began their journey on a small scale in Greiz, Germany. Over the decades, demand grew significantly due to its exceptional performance in extreme environments, and the product quickly developed into an indispensable ingredient in a wide range of applications for industries such as construction, automotive, aerospace, marine, and energy.  

“This innovative solution celebrates 60 years of pioneering contributions to modern society, which is a remarkable milestone,” said Sylvia Winkel Pettersson, Vice President Engineered Polymers at Nouryon. “Research and development have been an important part of Nouryon’s operations since its inception and we constantly strive to find new solutions for our customers. Today we are one of the largest producers of liquid polysulfide polymers in the world."  

From its modest beginnings as a single resin, Thioplast® polysulfides of today have transformed into an advanced solution offering formulators an array of possibilities. This includes thiol-terminated Thioplast® G polysulfides and epoxy-terminated Thioplast® EPS polysulfides, accompanied by a wide range of curatives, from oxidants to epoxides. 

But the remarkable story of Thioplast® polysulfides doesn't end at 60 years. As technology evolves and industries face new challenges, the versatility and adaptability of liquid polysulfide polymers hold the promise of even greater contributions. Thioplast® polysulfides remain poised to drive innovation, sustainability, and safety in a rapidly changing world.
