Kraton Announces Plans to Showcase Latest Advancements in Elastic Nonwovens, NEXAR(TM) Polymers for Performance Fabrics, and C5 Resin Alternatives for Adhesives at INDEX 11 GENEVA PALEXPO, April 12-15, 2011, Geneva, Switzerland

HOUSTON, March 24, 2011 - Kraton Performance Polymers, Inc. (NYSE: KRA), a leading global producer
of styrenic block copolymers or "SBCs," announces plans to showcase and
discuss its latest innovations in elastic nonwovens, NEXAR(TM) Polymers, and
C5 Resin alternatives for adhesives at INDEX 11 in the GENEVA PALEXPO
Exhibition and Conference Centre, Geneva, Switzerland.

INDEX 11, which is considered to be one of the world's leading nonwovens
exhibition, is the ideal venue for Kraton Polymers to showcase its latest
innovations in adhesives, elastic nonwovens, and NEXAR polymers for
performance fabrics. "We believe that INDEX 11 will provide tremendous
opportunities for knowledge sharing and collaboration, which has historically
resulted in new, innovative, and specialized product solutions that meet the
most rigorous industry demands for higher-performance," said Mark Siebert,
Vice President, Adhesives, Sealants and Coatings. "We expect that key
players-from all application sectors around the world-will be in attendance,
and we look forward to helping them find solutions to their innovative
challenges and product shortages," he concluded.

Kraton scientists and executives will be at the company's showcase in
booth 4215 to discuss the features, benefits and applications of Kraton's
latest innovations in the following end uses:

Elastic Nonwovens for Single-Use Disposables and Durable Fabrics: Kraton
Polymers' new polymer technology offers superior softness, bi-axial stretch
and solid durability breaking through the process barriers of conventional
styrenic block copolymers. The competitive advantage lies in the design and
optimization of the copolymer while still being suitable for high speed
processing. These elastic nonwovens are proven to be drapeable and non-tacky
enabling the creation of products that are soft, quiet, and discreet. Kraton
polymers impart the stretch and flexibility required in personal care
products and offer improved comfort in items such as scrub suit apparel,
medical gown laminates and wound care dressings. These polymers paired with
polyester and nylon making interesting fabrics for uniforms, outdoor apparel
and furnishings.

NEXAR(TM) Polymers (Performance Fabrics): NEXAR polymers' selectively
permeable membranes and coatings provide a unique solution that addresses the
needs of textile innovators for high performance and breathable fabrics. They
can be used in sports apparel, outdoor apparel and gear, military and
industrial uniforms, as well as medical and geotextile applications. NEXAR
polymers are lightweight and flexible, offer selective permeability in a
nonporous membrane, deliver an excellent moisture transmission rate, do not
require special equipment or processes, provide high strength in wet and dry
environments and are chemical and chlorine resistant.

Adhesives: Kraton Polymers has technologies that can be used in hot melt
formulations to support the needs of market growth while reducing the demand
on C5 resins. These adhesives can be used in tapes and labels and are
considered to be the cornerstone technology for diaper and feminine napkin
construction. Styrenic block copolymers in conjunction with C5 and
aromatic-modified tackifying resins have been the preferred choice given
their wide formulation latitude and application ease. Kraton Polymers has
developed an alternative solution that requires 15% less C5 while delivering
similar adhesion properties and formulated costs to current industry standard
formulations. Our unique SIBS based polymer provides an immediate option to
support the growth and innovation needs of innovators without sacrificing
performance. In addition, our latest developments can be extended to SBS
polymer grades typically used for nonwoven construction. Kraton Polymers'
research and development efforts continue to explore new chemistry options to
reduce the dependency on scarce formulating ingredients.

In addition to the product showcase highlighted above, attendees are
invited to attend the presentation of two technical papers by Kraton Polymers
research scientists Martine Dupont and John Flood, respectively. The first
presentation, entitled Kraton Polymer Technologies Reduce or Eliminate C5
Tackifying Resins, will be held on Tuesday, April 12, 2011, from 4:00 p.m. -
4:20 p.m. The second presentation, co-authored by The Nonwovens Institute,
North Carolina State University, is entitled Elastic Nonwovens Using Styrenic
Block Copolymers: the Next Generation of Spunbond and Melt Blown Fabrics for
Durable and Disposable Applications. This presentation will occur on
Wednesday, April 13, from 11:50 a.m. - 12:20 p.m.

We invite you to attend the technical presentations and stop by Kraton
Polymers booth 4215 at INDEX 11. To schedule a personal consultation with our

About Kraton Polymers

Kraton Performance Polymers, Inc., through its operating subsidiary
Kraton Polymers LLC and its subsidiaries, 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 almost fifty 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. Our polymers are used in a wide range of
applications, including adhesives, coatings, consumer and personal care
products, sealants and lubricants, and medical, packaging, automotive,
paving, roofing and footwear products. We currently offer approximately 800
products to more than 700 customers in over 60 countries worldwide, and are
the only SBC producer with manufacturing and service capabilities on four
continents. We manufacture products at five plants globally, including our
flagship plant in Belpre, Ohio, as well as plants in Germany, France and
Brazil, and a joint venture plant operated in Japan.
