Special auxiliary to prevent yellowing of polyamide and polyamide/Elastan articles during heat treatments (e. g. heat-setting and/or molding).
- Prevents yellowing caused by heat treatment
- Particularly useful for directly heated stenters, where NOx-formation is a problem
- Especially useful for articles which are fluorescent whitened or dyed in pale shades
- Prevents oxidation of amino-end groups of polyamide caused by heat treatment
- Highly suitable for molding articles
