STYRON™ C-TECH Polystyrene

STYRON™ C-TECH Polystyrene is a cost-efficient, transparent, high impact polystyrene (HIPS) grade for food packaging converters.

Trinseo created STYRON™ C-TECH Polystyrene in response to the growing consumer demand to preview food purchases on the shelf.

STYRON™ C-TECH Polystyrene is used in several extrusion applications including transparent food containers produced using the conventional extrusion/thermoforming process. STYRON™ C-TECH Polystyrene is also used as an impact modifier in biaxially oriented polystyrene (OPS) sheet for the production of bakery and delicatessen packaging items, and as a gloss cap layer in opaque sheets, e.g. for refrigerator door liners. In these applications, its excellent processability and high gloss – together with its exceptionally low odor and taste levels – improve on traditional transparent resin blends.

STYRON™ C-TECH Polystyrene shows a balance between clarity, stiffness, and toughness. The clarity is achieved through adequate processing conditions during thermoforming. The improved stiffness enables down-gauging and additional cost savings through product substitution. These polystyrene resins offer:

  • Transparency with lower formulation costs
  • High gloss
  • Good toughness
  • High stiffness
  • Optimal thermoforming properties
  • High melt flow rate
  • Lower extrusion temperatures
  • Exceptionally good organoleptic properties
  • Excellent processability and high processing speeds

Trinseo offers a complete line of polystyrene materials in Europe and Asia Pacific. Polystyrene resins are available in North America through Americas Styrenics, a joint venture equally owned by Trinseo and Chevron Phillips Chemical Company LP.
