Since ancient times, bitumen has been used as a sealant and adhesive due to its remarkable waterproofing properties. In the modern world, it has long been used in many civil engineering applications, such as paving and roofing. While it has been added to asphalt mixes for decades, unmodified bitumen can become too brittle at low temperatures and too soft at higher temperatures. As cities throughout the world develop increasing dependency on reliable and age-resilient infrastructure, the limitations of unmodified bitumen create far too many challenges for contractors and civil engineers. Unmodified bitumen cannot stand up to the wear and tear caused by traffic and harsh climates. Increasing demands for safer roadways and roofing structures, in addition to tightened infrastructure budgets and a surge in noise pollution, create the need for new 21st century solutions.

Kraton Performance Polymers is helping infrastructure innovators rise to these challenges through the use of our innovative polymer technologies specifically designed for bitumen modification. Today, millions of tons of polymer modified bitumen are used globally, creating longer lasting, cost effective roadways and waterproofing technologies in countries throughout the world.

From our proven Highly Modified Asphalt (HiMA) technology, to our differentiated and innovative polymer grades for roofing materials, our products for bitumen modification are at the forefront of today’s paving and roofing industries. These industries are constantly changing, and to meet the challenges our customers face, Kraton offers a diverse array of styrene-butadiene-styrene (SBS), styrene-isoprene-styrene (SIS) and styrene-ethylene/butylene-styrene (SEBS) polymer modification options. Our science goes above basic polymer modification, providing grades specifically invented for roofing and paving applications.


As traffic becomes denser, axle loads and tire pressures continue to wear down roadways across the world, while harsh climates and weather spur the deterioration. Over time, roads become rutted, rough and deformed which can lead to dangerous, and costly, repercussions. To enhance a road’s durability, the SBS polymer modification of asphalt binder has become the solution of choice. Polymer modification offers the features and benefits that meet the evolving expectations of drivers, road authorities and communities the world over. As pioneers in asphalt modification, Kraton leads the paving industry by offering new and innovative SBS polymers that deliver superior performance and processability. With a vast global supply network, we offer our platform of higher performing SBS polymers to an ever challenging range of paving applications.
