Function: Stabaxol® KE 7646 is a polycarbodiimide-masterbatch; carrier polymer: polyethylene terephthalate (PET). Antihydrolysis agent for thermoplastic polyesters, especially for PET. Stabaxol® KE 7646 is used in PET-monofilaments for dryer-conveyor belts in paper making machines where it assists to multiply the service life time. For example by as much as three times after accelerated ageing in saturated steam (121 °C/ 250 °F).Information provided by Lanxess. |
