About Kraton

Kraton is a leading global engineered polymer company 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.
