SUMIKAEXCEL PES has good heat resistance of about 200°C and has excellent impact resistance and steam resistance, so it is good for steam cookers and for cookwares and tablewares for foods containing fats and oils. Some grades of SUMIKAEXCEL PES comply with the regulations for food contact materials in various countries.

Features

• High heat resistance and cold tolerance
  • Cooking is possible at a wide temperature range of -40°C to 200°C.
  • Capable of being used in freezers and also of cooking oily foodstuffs.
  • Resistant to rapid temperature changes, such as quick freezing and microwave oven heating from frozen.
  • Microwave ovens can be used.
  • Steam cooking is applicable.
• Thermal conductivity
  • With moderate thermal conductivity, heat is transferred to the ingredients evenly during cooking.
  • When removed from the heat source, it cools relatively rapidly that allows for quick and safe handling.
• High durability
  • Excellent durability allows for long-term use.
  • Washing with common detergents and bleaches is possible.
  • Use under conditions where metals would corrode is possible.

  • Even when heated to high temperatures, there is almost no gas emission or leaching of components.
  • Resistant to impact and not easily broken.
• Lightweight
  • Lightweight and easy to carry and handle.
• Design
  • The original color is light amber, and it is transparent with calm tones.
  • Various shapes and designs can be applied due to its good processability. Also, various processing methods can be selected.
  • Coloration is possible.
