Kraton Polymers' Innovation Reaches New Heights
(BUSINESS WIRE)
Kraton Polymers LLC (Kraton), a leading global producer of engineered
polymers announces an innovation with proven ability to double
styrene-butadiene-styrene
(SBS) modification levels in pre-modified asphalt emulsions. These
new high polymer content (HPC) emulsions are a result of
Kraton
Polymers utilizing its latest development in high vinyl products.
The effects of the enhanced mechanical properties can enable a
transformation of traditional modified asphalt emulsion applications as
well as open the door to new opportunities.
The modification levels in atmospheric emulsification systems
historically have been limited to three to four weight percent of SBS
polymer based on asphalt. Higher percentages can result in increased
average and broad particle size distribution leading to insufficient
emulsion stability and viscosity or inadequate drying and curing
behavior. The pressurized emulsification systems have the capacity to
increase the level to five or six weight percent.
Kraton Polymers' innovation allows for low pre-modified asphalt
viscosity and emulsions to be created with polymer contents up to eleven
weight percent in atmospheric emulsification systems. The polymer
content can be substantially higher in pressurized emulsification
systems. The performance advantages can be tuned through selection from
Kraton Polymers' portfolio of high vinyl polymer grades. The potential
applications for the HPC emulsions also include:
|
-- Surface dressing/Chip Seals
|
|
-- Fog seal
|
|
-- Micro surfacing
|
|
-- Cold-applied crack or joint sealant
|
|
-- Slurry Seals
|
|
-- Pre-modified SBS emulsions for warm mix
|
|
-- Stress-absorbing membrane interlayer (SAMI)
|
|
|
|
-- Tack coat / Trackless tack coat
|
|
|
The new high polymer content can also be applied in asphalt
emulsion-based waterproofing applications; modified roofing membrane
base sheets, bridge deck seals and standard or below-grade residential
and commercial waterproofing membranes. They can be formulated as
temporary, permanent as well as spray-applied systems. In addition, the
benefits of HPC emulsions can be achieved in several other industrial
applications such as pipe and metal coatings. Kraton Polymers is the
world's leading supplier of SBS block copolymers for asphalt
modification and continues to be the gold standard in the asphalt
industry. For decades, its SBS grades have been widely used in
pre-modified asphalt emulsions. Kraton Polymers will continue its long
tradition of pushing innovation to new heights and providing solutions
to its customers in the asphalt emulsion industry.

About Kraton Polymers
Kraton is a leading global producer of engineered polymers and, we
believe, the world's largest producer of styrenic block copolymers
(SBCs), a family of products whose chemistry was pioneered by us over
forty years ago. SBCs are highly-engineered thermoplastic elastomers,
which enhance the performance of numerous products by delivering a
variety of attributes, including greater flexibility, resilience,
strength, durability and processability. Kraton polymers are used in a
wide range of applications including adhesives, coatings, consumer and
personal care products, sealants, lubricants, medical, packaging,
automotive, paving, roofing, and footwear products. Kraton has the
leading position in nearly all of its core markets and is the only
producer of SBCs with global manufacturing capability. Its production
facilities are located in the United States, Germany, France, The
Netherlands, Brazil and Japan.
