A fiber option for fire-performance development

The range includes colored virgin polyester staple fibers with an intrinsic flame-retardant modification. A modifier is incorporated into the polymer rather than relying only on a surface treatment. Select the linear density and cut length for the intended blend and processing line.

Read the demonstration in context

The demonstration video compares modified and standard polyester under a 10-second flame exposure. Observe ignition, flame spread, dripping and residual char. This demonstration is not a certification or a guarantee for every grade. Ask for a test report identifying the sample, method, date and result.

Applications and qualification

Potential uses include automotive acoustic layers, headliners, seat linings, contract upholstery, curtains, mattresses and technical padding. Protective clothing and other safety-critical uses require their own material and finished-product qualification. Specify the destination market, final assembly and required fire test before choosing a grade.

Performance to confirm

Review fire behavior after aging or cleaning, smoke requirements, colorfastness, mechanical recovery and processing compatibility. The catalog's LOI and fire-standard references are requirements to verify with applicable evidence, not blanket promises of compliance.

Available grades

Catalog reference values. Confirm the agreed grade, net weight, packaging and minimum quantity in the quotation.
