Kraton gives roofing innovators their edge by providing the widest range of polymer grades, including new and differentiated grades that go above and beyond basic modification to help create roofing structures that not only withstand the elements of challenging climates, but are also long lasting and cost efficient.
Reaching beyond design and basic functionality, the roofing industry is experiencing a great influx in the demand for financial and environmentally sustainable solutions. The quest for lower cost and ecologically sensible roofing materials is driving markets across the globe. In many parts of the world, roofing requirements are changing due to new government or climate-driven requirements. Additionally, aesthetic and architectural needs continue to change, impacting the roofing market and its need for unique, ground-breaking polymer technology.
Kraton® styrenic block copolymers (SBCs) are used in modified, bituminous roofing materials and create a vast balance of properties, including flexibility over a wide range of temperatures and resistance to thermal degradation. Our technology is designed to exceed increasing demands the world over for more economic materials, and meet a wide range of criteria, including peak performance over long time periods, ease of application and aesthetics.
The technologies we have helped create aid in the production of such roofing applications as:
- Commercial modified bitumen roofing (felts and membranes)
- Self-adhesive modified bitumen roofing
- Modified mopping asphalt
- Modified laminating adhesives
- Modified tab adhesives
- Modified Shingles
- Elastomeric Reflective Roof Coatings - Read More>>
Features and Benefits
Our SBS, SIS and SEBS polymer modifiers create a strong network within asphalt, enhancing the physical properties of the asphalt to create roofing materials that have a wide array of features and benefits, such as:
- Extraordinary water resistance
- Superior resilience to hail and wind damage
- Ability to withstand temperature extremes
- Exceptional durability
Differentiated & Innovative Grades for Roofing
While modified bitumen roofing membranes have been on the market for many years, there is an ongoing need to provide cost effective formulation solutions to deal with ever-changing bitumen supplies. These needs also apply to steep slope shingles, as well as a variety of waterproofing membranes which may require wider performance ranges for new roofing concepts.
Our roofing innovation team is intently focused on the future, and our goals are aligned with those of our customers – provide the best possible technologies to meet the demands of the global roofing innovators, while remaining cost effective. Our differentiated and innovative polymer grades for bitumen modification offer:
- Improved high and low temperature properties
- Lower processing viscosity
- Better compatibility with a range of bitumen
- More manufacturing flexibility
