What Should Be Paid Attention To When Choosing Plastic Additives

Plastic additives not only make the polymer easy to process, but also largely compensate for the lack of the polymer itself, such as improving the performance of the product and prolonging the service life. Therefore, it is no exaggeration to say that without the cooperation of processing aids, there is no development of the plastics industry.


Whether the plastic additives are selected correctly directly affects the processing, product performance and service life. When choosing additives, you need to consider the following questions:


1. Compatibility of additives with polymers

Compatibility refers to the ability of the additive and the polymer to be well mixed uniformly without precipitation of phase separation. The auxiliaries must be stably present in the product for a long period of time in order to perform their intended functions, so auxiliaries with good polymer compatibility should be used as much as possible.


2. Adaptability of additives to processing conditions

The same polymer, because of the different processing methods used, the plastic additives required are also different.


3. Give full play to the synergy of the helper

A plastic often uses a variety of auxiliaries, which are in the same system, often interact with each other, and if properly matched, have synergistic effects when used, called "synergy."
