High Flow HSBC Polymers

Kraton innovations push the boundaries of HSBC technology by commercializing differentiated high melt flow HSBC polymers specifically designed to offer to the market unprecedented performances.

 

KRATON™ G1653

This new developmental 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. It's low solution viscosity allows customers to increase solid content and decrease VOC of solvent-based products, yet maintain 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™ G1648

This new HSBC polymer is an extension of the Enhanced Rubber Segment series, which enables very low melt viscosity or very high melt flow rate.  Kraton™ G1648 has a melt flow rate that is approximately 10 times higher than the next best HSBC alternative. The step change in viscosity enables Kraton G1648 to be used in applications and processes not previously available to HSBC polymers due to the previous inherent limitations in HSBC viscosity. Example applications include textile adhesives, masterbatches with high filler loadings, automotive skins and elastic melt blown fabrics.


KRATON™ A6951

Due to its ease of use and compatibility, the Kraton A family has long been the product of choice for compounding, overmolding, sound damping and other similar businesses. The new Kraton™ A6951 product delivers the same reliable benefits of our traditional Kraton A family but with an additional enhanced flow capability never before seen in the market, which enables:

 

  • Tuning of performance involving haptics, damping and pressure-sensitive adhesion
  • Enhanced dispersion, improved processing performance and ability to go thinner in end-use applications
  • Efficient introduction of soft touch haptics, or softening characteristics in compounds
