Misconception 1: The more flame retardants, the better the flame retardant effect.

Flame retardancy performance of materials is related to the amount of flame retardant. As the amount of flame retardant increases, the flame retardant effect initially enhances and then diminishes. Adding an excessive amount of flame retardant significantly affects the mechanical properties of the material.

Myth Two: The higher the flame retardant grade, the better.

Different applications have varying requirements for flame retardancy. Generally, people always hope that materials have higher flame retardancy. However, in reality, each flame retardancy testing method has its limitations, and the conclusions are relative. For example, it is generally believed that higher flame retardancy is better; materials with the UL94V-0 rating are considered superior to the V-2 rating. However, some electrical products require materials with arc ignition resistance, where V-2 is better than V-0. This is because 94V-2 level plastics do not conduct or caramelize under electrical stress, significantly reducing the likelihood of ignition. Conversely, V-0 level plastics behave differently.

Misconception Three: PP Flame Retardant and Flame Retardant Masterbatch Are the Same

PP flame retardant is a powder suitable for modified granulation, requiring blending with other formulations. The PP flame retardant masterbatch is a composite formula made from a carrier, compounded flame retardant, and twin-screw granulation, which can be directly processed into products or granulated.
