In the production process of PP honeycomb board plastic products, it is inevitable to add various auxiliary agents to modify their functions, which may lead to excessive quantitative substances and ultimately result in non-compliance with specifications. This requires PP honeycomb board manufacturers to pay attention when planning the formula.
PP honeycomb board
1. For example, the most commonly used antimony trioxide requires controlling the lead mass fraction.
2. The mass fraction of octabromoether and pentabromoether in the bromine based flame retardants used in PP honeycomb panels, especially in decabromo flame retardants, should not exceed the standard, as some octabromoether and pentabromoether are inevitably carried in the production of decabromo.
3. Colorants. PP honeycomb board manufacturers should pay attention to the quality fraction of heavy metals when using inorganic coloring agents, such as cadmium less than 100%
