The needled non-woven fabric can withstand the following temperature of 200℃ under the dry pressure standard.
If there is water and chemicals will produce hydrolysis reaction.Needled nonwoven fabric is a polymeric polymer like polyester that hydrolyzes and simply bears a much higher temperature.
Needled non-woven fabric is the filter material of choice for the main purpose of high temperature where polyester will become brittle and unsuccessful.Its flexure resistance and wear resistance are better than most synthetic fibers.
The chemical fibers of needled non-woven fabrics cannot be waxed in non-thermosetting plastics, but can be singed or other post-treatment processes using unique techniques.
