Kraton Polymers Opens New Doors for TPE-S Compounds in High Temperature Applications

Kraton Polymers LLC (Kraton) a leading global engineered polymer
company, announces the commercialization of Kraton G1633(R) polymer
and the creation of new opportunities for TPE-S (styrenic
thermoplastic elastomer) compounds in high temperature, high
performance applications.

Kraton research has developed a new solution that allows customers
to match or outperform the performance of TPV (thermoplastic
vulcanizate) material when using Kraton G1633 with the right
combination of Polyolefin blends.

The innovation allows the automotive, medical, construction and
heavy-industrial sectors to achieve best in class performances and
long term durability combined with high quality aesthetics and lighter
weight. Kraton G1633 improves the compression set and stress
relaxation of TPE-S compounds at temperatures over 70 degrees Celsius.
It allows the production of TPE-S compounds with a broad hardness
range, excellent oil extendibility, very good processability in both
extruded and injection molded applications, recyclability and
extensive bonding possibilities when compared to alternative material
solutions.

Kevin M. Fogarty, Executive VP Kraton Polymers, comments: "Kraton
G1633 polymer provides a good example of how Kraton Polymers focuses
its innovation on advancing application possibilities for customers.
Its excellent combination of physical, hardness and processing
properties makes it the ideal solution for maximising the performance
of TPE-S compounds when high temperature performance is required. The
recent success of TPE-S for weatherseals in the European automotive
sector demonstrates the potential of TPE-S compounds to the worldwide
industry."

Kraton G1633 is acceptable for use under FDA and European
regulations for direct food contact applications, and meets
requirements under the United States Pharmacopoeia (USP) Class VI
Biological Reactivity Tests.

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.
