Technical Details & Test Data

Technical Data

Dosing depends on acid end group content and the humidity of the polymer to protect, as well as the expected degree of protection. For Polyester, Polyamide, and thermoplastic Polyurethanes we recommend 1.5 to 2.5 pbw. For millable Urethane rubber we recommend 0.5 to 5 pbw of Stabaxol® I LF.

Prior tests should always be carried out to determine the most suitable dosage, however. An addition of 2.5 pbw of Stabaxol® I LF will increase the lifespan of PET about four times. Usually Stabaxol® I LF may be dosed separately. It can be incorporated with all units of machinery suitable for processing Polyester or Polyamide while allowing for a proper additive dispersion. It is advisable to extrude with a twin screw extruder providing an L/D ratio of > 38. Please note that an extruder's feeding zone has to be kept heated in order to prevent material buildup in the feeding zone.
