HOUSTON, Sept. 21, 2016 /PRNewswire/ -- Kraton
Performance Polymers, Inc. (NYSE: KRA) is a leading global producer
of styrenic block copolymer (SBC). Kraton has a history of
innovation focused on driving growth for its customers. With a
broad portfolio of value-enhancing polymers used in a wide variety
of applications, we are pleased to introduce our newest innovation
polymer that we believe will enable our customers to further expand
their competitive edge.
Introducing Kraton G1653
The new developmental
polymer, Kraton G1653 polymer, is a
styrene-ethylene-butylene-styrene (SEBS) block copolymer. With
lower molecular weight than Kraton G1652 polymer, it still retains
the high tensile strength and toughness of Kraton G1652 while
offering significantly lower melt and solution viscosities.
Kraton G1653 is suitable for food contact and medical
applications.
Features and benefits
Although Kraton G1653 retains
similar physical properties as Kraton G1652, it has a much lower
solution viscosity than Kraton G1652. This low solution viscosity
increases solid content and decreases VOC of solvent based
products, yet maintains similar processability. For coating
applications, the increased solid level translates to potentially
reduced coating layers and lower labor cost. For sealant
applications, the increased solid content is expected to reduce
shrinkage and costs associated with solvent. Kraton G1653 also can
be dissolved in PCBTF at 20 percent solids, which may enable
formulators to replace organic solvents with PCBTF to reduce VOCs
associated with the final product.
The free flowing dense pellet form of Kraton G1653 is expected
to improve storage, handling, and feeding of the polymer in
comparison to SEBS polymers in powder form. The polymer has the
following qualities:
- Does not block together during storage
- Can be transferred using conventional pneumatic conveying
equipment
- Does not agglomerate when dissolving in solvents, and
- The dense pellet form may enable improved production rates
Potential market applications include:
Coating
applications, sealants, pressure sensitive adhesives, hot melt
adhesives, TPE compound, elastic compound, medical compound, color
master batch, additive concentrates, oil gel, and polymer
modification.
Prakash Kolluri, Vice President
Sales & Marketing Asia Pacific noted, "Kraton G1653 is another
new Kraton innovation polymer that was developed to meet the market
trend toward lower viscosity, high flow, and lower processing
temperature. We expect that Kraton G1653 will allow our customers
to meet the tight VOC regulatory requirements without sacrificing
performance and processability."
(NTD: covered in the "About Kraton Polymers" section below)* The
product Kraton G1653 will be offered under the name Kraton MD1653
until fully commercialized.

Kraton G1653 offers significantly higher melt flow and lower
solution viscosity than its conventional SEBS analogue. This allows
formulators to develop high flow compounds with excellent
properties without adding excessive oils. Compounds based on Kraton
G1653 can also be extruded or molded at lower temperatures. For hot
melt adhesives, the lower melt viscosity translates to lower
processing temperatures, which is expected to reduce energy
consumption and improve production rates.
Kraton G1653 has the same low rubber phase Tg (-48.5°C) as the
conventional G1600 series polymers. This rubber Tg allows the
polymer to remain flexible and elastic at low temperatures. G1653
can also be compounded with random copolypropylene and extruded
into clear films with superior toughness for medical applications.
Such films can be heat sealed and sterilized. It can also be used
as an impact modifier for rigid polymers or as an interfacial
compatibilizer for polymer alloys or blends.
Packaging and availability information
Kraton G1653 is
produced at Kraton's Belpre plant. It is available immediately in
commercial quantities. Please contact your Kraton representative or
distributors for samples.
