  • Drinking cups (hot and cold)
  • Take-out containers
  • Ice cream containers
  • Labeled and printed cups
  • Thin-wall cups at high density
  • Noodle bowls
  • Soup containers

Attributes:

  • Good thermal insulation
  • Superior temperature retention

  • Strong and lightweight
  • Superior taste and odor properties
  • Superior barrier resistance to spicy oils and foods
  • Improved leak resistance for hot and cold beverages

The thermal conductivity of expanded polystyrene at an average temperature of 75°F (24°C) is lowest at 3.5 pounds per cubic foot (pcf). It rises slightly at lower density until about 1.5 pcf where it increases rapidly. The rate of increase is much less at higher densities:

  • 8.0 pcf (128 g/l) - 0.269 Btu-in/(hr-ft2-°F) or 38.7 mW/(m-K)
  • 12.0 pcf (192 g/l) - 0.276 Btu-in/(hr-ft2-°F) or 39.8 mW/(m-K)

United States: DYLITE F271TN complies with the U.S.A. Food and Drug Administration (FDA) Code of Federal Regulations 21 CFR 177.1640 for polystyrene and 21 CFR 178.3010 for blowing agents. Thus, DYLITE F271TN may be used in the United States as an article or a component of an article intended for use in contact with food, subject to any limitations described in the regulations.

Canada: NOVA Chemicals has received a letter from the Health Products and Food Branch indicating no objection to the use in Canada of DYLITE F271TN for a variety of food packaging applications.

Europe: DYLITE F271TN complies with the European Union's food contact regulations including the Framework Regulation (EC) No. 1935/2004, Regulation (EC) No. 2023/2006 (GMP) and Regulation (EU) No. 10/2011, as amended, Annex I (including Table 1, Union list of authorized substances) and Annex II.

NOVA Chemicals EPS resins are biologically and chemically inert. NOVA Chemicals EPS resins are do not contain CFC's (Chlorofluorocarbons).
