The new Cesa tracer concentrates are currently available for polyester and polyamide (nylon) fibers, including recycled grades. In the case of recycled grades, fiber manufacturers can use the tracer concentrate pellets earlier in the production process by adding them to the recycled polymer content (e.g., polyethylene terephthalate bottle flakes or shredded nylon fishing nets) prior to being extruded into pellets.

ColorMatrix™ Amosorb™ non-nylon based Oxygen Scavengers create an active barrier against oxygen ingress to help you enhance product protection and extend shelf life. Non-nylon based

Targeted at products for the consumer market, Artisan™ nylon (PA6) is the first material in a series of high-gloss, scratch-resistant pre-colored thermoplastics formulated to replace paint. The Artisan nylon grade is globally available in a range of customizable colors.

Joining Edgetek™ PKE and LubriOne™ PKE materials launched in 2021, Complēt PKE formulations can provide alternatives to nylon (PA) and acetal (POM) based formulations, offering added supply security and sustainable benefits.   Complēt PKE formulations are semi-crystalline and deliver excellent chemical resistance, low moisture uptake, and dimensional stability similar to nylon (PA66).
