What kinds of additives are added to the plastic modifier

Plastic modified materials need to go through professional deep test and fat dissolving test. Through professional analysis, the main test and analysis of the physical properties of the product can select the suitable modified materials. The selection of plastic modified materials is directly related to the cost of the product. The cost-effective plastic modified materials can even save more than half of the processing costs. In addition, the easy-to-use plastic modified materials need to be improved Different kinds of additives should be added.

1、Heat aging additive

This kind of additive is to effectively improve the heat aging resistance of plastic modified materials by adding. The common heat aging resistance additives include antioxidant and metal chelating agent. The former has a large amount but relatively high cost. Many plastic products have higher requirements for heat aging resistance, and the heat aging resistance has a great relationship with the life of plastic products after molding.

2、Light aging resistant additive

This kind of additive is not uncommon. Most operators did not pay much attention to it during the production. The light aging resistant additive is relatively less in the production process of plastic modified materials. This kind of additive includes light absorbers and light stabilizers, which are widely used but have a large amount of elastic space. However, the editor suggests that not all plastic modified materials need to add light aging resistant additives Chemical additives.

3、Additives for processability

According to the highly evaluated suppliers of plastic modification materials, the various types of additives can improve the different properties of polymers respectively. The first improvement is the processing performance to reduce the processing cost and improve the product quality. The processing performance additives mainly include lubricants and various high and medium quality processing aids, in addition to plasticizers and release agents.

If there are certain requirements for the appearance of plastic modified materials, it is also necessary to add colorants and fluorescent whitening agents, etc. as appropriate, but the use amount has strict regulations. At present, many plastic products simply improve the appearance, so the amount of colorants is gradually reduced. From the transformation of material properties, it is also divided into mechanical properties additives.
