The polymer is easy to be destroyed and degraded by all kinds of factors in the process of using. The anti-aging additives can help polymer materials resist aging degradation. Especially for products with high requirements for weather resistance, more additives need to be added. However, the high amount of additives may lead to precipitation problems, especially in some thin products such as films and coatings. Excessive additives are very easy to migrate and precipitate in the process of using which has also become one of the problems puzzling customers.
In order to control the precipitation of additives, below measures are widely used:
● Select additives with better compatibility with the matrix to improve its stability at low temperature;
● Raise the processing temperature to increase the interaction between molecules and reduce the possibility of precipitation;
● Adjust the formula and add a variety of different additives to improve the overall solubility.
However, the above measures can only delay precipitation. In order to solve this problem, DELTACHEM launched a new generation of additives - OMNISTAB ® RA series reactive additives.
The reactive functional activity are attached to conventional promoter molecules to produce the reactive additives. Reactive activity can react with the substrate or participate in the polymerization of the polymers, then strong chemical bond is produced to overcome the above shortcomings and effectively avoid the occurrence of segregation. Reactive additives effectively improve the weather resistance of polymers with the advantages of good compatibility, extraction resistance and long service life.
Reactive additives are very suitable for these applications where the traditional UV absorbers cannot fully meet the requirements such as coatings, films and fibers.
