Polyester Fibre Nonwoven
Lightweight polyester nonwovens act as an effective support for films or fragile materials. Featuring exceptional dielectric and acid resistant properties, polyester fibre nonwovens are an ideal solution for many applications.
Polyester Fibre Nonwovens
Why Polyester Nonwovens?
Our lightweight polyester nonwovens share similar properties with our range of glass nonwovens, and are ideal substrates for carrying active materials. They act as a lightweight support layer to enable rapid even wet out of active material, creating a uniform dispersion and improved handling of the final product.
Polyester exhibits properties unlike glass, which makes it a more relevant option for acidic environments, and applications that require a higher level of formability and flexibility.
