    FOYLON 7440: Flexible, Lightweight & Durable Heat Reflective Materials

Whether you are seeking to maximize the power of artificial light, develop a thermal management strategy, or protect against harmful UV-rays, FOYLON® 7440 can do it all. Foylon is a laminated, reinforced energy reflection fabric made of fiberglass and aluminum. There are a wide variety of other reflection fabrics and materials out there like Mylar, aluminum foil, synthetic polymer films, and more. But Foylon is unique in its ability to maintain a reflectivity of 95% while remaining flexible, lightweight, and extremely durable in stressful environments and tough jobs.

Here are some of the typical physical properties of FOYLON® 7440:

Test and Methods Result Unit

  • Burn Length (MD/CD)
0.8 / 0.8 ± 0.2 inches

When used in everyday applications, these physical properties translate into tangible advantages that make Foylon a standout among other heat and light reflection fabrics. For example, Foylon is extremely durable under tough conditions like high temperatures and open flames. It will not fade, crack, or tear even after many years of service in a stressful environment. Due to its durability, Foylon can be easily positioned, cleaned, and maintained without fear of damaging the fabric.

Moreover, Foylon disperses both heat and light in an even pattern. At first, this may not sound like an important capability, but it is essential for preventing hot spots from forming. Hot spots are failure areas that form on reflective fabrics when a given material is scratched, creased, deformed, or weakened due to the concentration of heat and light. For instance, Mylar is prone to hot spots because the fabric is a smooth sheet that unevenly reflects heat and light. You’ll never have to worry about Foylon forming hot spots or failing due to wear and tear.

Because Foylon is highly reflective and extremely durable, it is typically more expensive than other common reflective fabrics. However, its incredible longevity and long-term energy savings are well worth the initial cost.

With these amazing physical properties and in-service advantages, Foylon has been used as a heat and light reflective solution in a wide variety of industries.

Here are some of the applications for Foylon:

  • Heat barrier curtains
  • Mattress and furniture flanging
  • Protective covers
  • Aircraft instrument shields
  • Greenhouse
  • Home insulation
  • Aerospace
  • Tents and shelters
  • Industrial design
  • Shipping
  • Protective clothing
