Among all polymers, polyolefin plastic has high cost-effective, good processing performance, which make it popular in the market. Even in harsh outdoor conditions, the weather-resistant PP material modified by additives can still maintain excellent yellowing resistance and anti-aging properties. Weather-resistance polyolefin plastic has been widely used in small household appliances shell, outdoor household appliances (such as air conditioning shell), automotive interior/exterior decoration and other fields.
However, the polyolefin composite without modification has significant defects: it is not resistant to high temperature and easy to photothermal oxygen degradation, which further causes the reduction of viscosity and product appearance problems.
OMNISTAB SOLUTION:
OMNISTAB UV3853 is a long-chain hindered amine light stabilizer with remarkable anti-photo oxidation aging effect. Its aging-resistance is better than that of common UV absorber and quench agent (nickel chromium compound)in polypropylene.
Different from traditional UV absorbers, its effect is not influenced by product thickness, so it can be widely used in thick PP parts and high specific surface products (such as PP film, fibre, etc.). It is high efficiency, at the same time it has good compatibility and dispersity with resin.
²Advantages of OMNISTAB UV3853：
Advantages of OMNISTAB UV3853：
When combined with other HALS, especially high molecular weight HALS (e.g. OMNISTAB LS119) and Benzoate UV absorbers (e.g. OMNISTAB UV2908), it can play a good synergistic effect.
Additive package "OMNISTAB UV3853+ OMNISTAB UV2908" is mostly used in the formula of air conditioning shell in the ratio of 4:1.
This solution has excellent protection effect on the surface color and gloss stability of products. After adjusting the proportion, it can also be used in automobile exterior decoration.
In the polyolefin system （polyethylene, polypropylene and TPO）, UV3853 could improve product’s color stability and weather resistance.
Compared with other small molecular weight HALS, UV3853 has a long alkyl chain, which ensures its excellent compatibility and solubility in polyolefin, without frost spraying.
