• Polytetrafluoroethylene (Expanded PTFE Teflon), also known as expanded Teflon, is a material with great chemical resistance (it is only affected by molten alkali metals and fluorine gas) and excellent dielectric and non-stick properties.
  • Belpaflon PL sheets, are made of expanded PTFE with special particles incorporated in order to increase its resistance to heat deformation.
  • This expanded Teflon has high chemical resistance including resistance to powerful acids and bases at high levels of concentration (sodium hydroxide, potassium hydroxide, nitric acids, sulfuric and hydrochloric acids)
  • This material is specially designed for use in conditions where both chemical agents and high pressures and temperatures are in play; it will improve on the performance of traditional PTFE sheets.
  • It is easy to cut and easy to disassemble from the flange, owing to its anti-stick properties.
  • It is not inflammable and it does not age. Especially recommended for chemical and petrochemical industries, as well as in the paper industry.
