Styroflex 2G66

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
  • High flow

Applications

  • Food packaging and films
  • Stretch hood/ stretch film
  • Impact modification / ESCR improvement
  • Compounding, compatibilization, recycling
