VFI®-5208 8 PCF Flexible Polyurethane Foam

VFI®-5208 8 PCF Flexible Polyurethane Foam is an 8lb per cubic foot, flexible pour foam that is compressible while also having good bounce back. VFI-5208 is a two part, one to one by volume foam that works in any machine injected system while also having a slow enough gel time to allow hand pouring. VFI-5208 Flexible Polyurethane Foam has a styrene backbone for increased stiffness and will not fully compress allowing the foam to hold its shape better than other flexible foams. With a fast final cure speed and the ability to over pack, VFI-5208 offers options to create many different parts and shapes.

8 PCF Two-part polyurethane foam that is a flexible foam and is not fully compressible.

Product Details

  • Product Color: Standard color available is white. For additional premium colors or color matching services contact Volatile Free, Inc.
  • UV Stability: This product is NOT UV color stable and has no long-term UV testing. For additional information contact Volatile Free, Inc.
  • Coverage/Thickness Requirement: Contact Volatile Free, Inc. for thickness requirements and specifications.
  • Storage Stability/Shelf Life: 12-month shelf life from date of manufacture when stored and sealed in unopened containers between 40°F - 75°F. Opened containers may be resealed with a nitrogen purge, but shelf life will be significantly shortened. Material should be brought to a minimum temperature of 65°F before use.
  • Equipment: For instructions and equipment requirements, contact Volatile Free, Inc.
  • Surface Preparation: All surfaces should be cleaned, prepped and free of any oils, dirt or debris. To demold, material must be non-porous or sealed with a chemical sealant. A release agent should be used on all products intended to be demolded. Contact Volatile Free Inc. with any additional questions.
  • Mixing: Pre-mixing Poly (B) components until uniform is required before combining Poly (B) and Iso (A). If pouring material by hand pre-weighed poly (B) must be poured into pre-weighed Iso (A) and then mixed until uniform and transferred to a new container to mix until uniform again before use. Product must be fully mixed and used before the duration of the cream time (initial rise). Mix times may vary depending on volume and mixing method, please contact Volatile Free, Inc. for more information on any specific mixing questions and requirements.
  • Material Application: Temperature should be between 50°F and 100°F when the product is being used. The pot life will shorten with any increases in temperature beyond 72°F. Ensure surfaces in contact with the material are properly sealed and released before mixing to prevent any unwanted adhesion. Contact Volatile Free, Inc. for more information on recommended release agents or sealants.
  • Primers: Contact Volatile Free, Inc. on any primer questions.
  • Cleanup: Preferred clean-up solvent is xylene or MEK. Please contact Volatile Free, Inc. for more information on clean-up of equipment and tools.
  • Thinning: Do not thin prior to application.
  • Precautions: Contains isocyanate that may be irritating to the skin and is toxic if inhaled as particulate matter. See Safety Data Sheet for complete safety data. Do not add any foreign material to this product. Avoid prolonged breathing of vapors and prolonged or repeated skin contact. Use only with adequate ventilation.
