Such combination systems often show a level of light stabilization performance far exceeding HALS or UV absorbers used alone and are particularly useful for the light stabilization of polyolefins (PE, PP, TPO), Styrenics (ABS, SAN, PS, SEBS, SBS), rigid PVC, polyacetals, polyurethanes, polyesters (PET, PBT) and polycarbonate (PC/PC blends).
SABOSTAB® UV 37 acts also as an effective processing and thermal stabilizer.
Features:
- UV and thermal stabilizer, radical’s scavenger and acid resistant.
- Strong synergistic performance when used in combination with HALS and/or UV absorbers and in presence of fillers or pigments
- Not-alkaline and non-interactive with other formulation components
- Non-discolouring, low volatility, good resistance to high temperature and extraction, excellent compatibility, low color contribution and low toxicity.
Hindered Amine Light Stabilisers (HALS)
HALS exhibit an unmatched effectiveness to inhibit photodegradation mechanisms that lead to undesired changes in plastic articles, such as cracking, chalking, colour changes and finally loss of physical properties.
