Styroflex 2G66

Overview 

 

Ineos Styrolution Styroflex 2G66 is a styrene-butadiene block copolymer (SBC) with the properties of a thermoplastic elastomer (S-TPE) suitable for extrusion (blown and cast film) and for injection molding. Styroflex® 2G66 is also used for polymers modification and compatibilization. It is more polar than comparable SBS or SEBS grades and offers a combination of high resilience and toughness with good transparency and process stability.

Key Features 

 

  • Excellent thermostability
  • Very high elongation at break
  • High resilience
  • High transparency
  • Regulatory compliant
