PTFE cloth YS9004AJ, thinnest fabric in premium series

PTFE cloth YS9004AJ, thinnest fabric in premium series

  • PTFE fabric YS9004AJ is the thinnest fabric in the Premium collection,
  • Since the basic fiberglass is almost transparent and light as a feather, the coating process is more difficult, and the final 0.04mm PTFE fabric is also almost transparent because you can see the other side through the Teflon fabric.


PTFE cloth YS9004AJ, thinnest fabric in premium series

  • ESONE’s premium series includes the thinnest PTFE cloth available, YS9004AJ. The manufacturing process is challenging due to the lightweight, near-transparency of the underlying fiberglass material. As a result, the final 0.04mm PTFE fabric is also almost transparent, allowing for visibility through the Teflon material.
  • In applications where high-quality Teflon fabric is required, using thinner PTFE fabric can yield better results. However, manufacturing thin PTFE fabric can be difficult, as the underlying fabric is susceptible to damage during the coating process.
  • To meet the demands of customers seeking durable, yet thin Teflon-coated cloth, ESONE utilizes a specialized coating process and formula.
  • ESONE premium series PTFE cloth has following properties.
