Flame retardant synergist addition and performance requirements

Mar 30, 2019

Flame retardant synergists are mainly based on nitrogen, phosphorus compounds and metal hydroxides, and also include nitrogen and phosphorus expansion systems, graphite expansion systems, compounds of such systems, which are non-volatile during combustion. It does not produce corrosive gases and is called a pollution-free flame retardant, which is a trend of development.

Flame retardant synergists are relatively large in addition, high in cost, and affect physical properties. In order to reduce the amount of addition, optimize physical properties, and improve flame retardant effect, researchers have utilized emerging nanotechnology, capsule coating technology, and surface treatment. Technology and compound synergy mechanism research and development of new flame retardants, including MMT, synergist FR-18, etc., with the main role of halogen-free flame retardant, play a role in the entire flame retardant compatibility system, coordinate physical properties, improve The synergistic effect of the flame retardant effect. Generally, the synergist added amount is much less than the main flame retardant, reducing the amount of the main flame retardant.

The new synergist reduces the required level of flame retardant (FR) additives and synergizes with polyamide (PA) to provide excellent flame retardant (FR) properties, including: charcoal, anti-dripping And reduce heat. Tests have shown that after adding 13 wt% of phosphinate and 2 wt% of Dow CorningĀ® 43-821 additive, 30% of the glass-filled PA compound has a UL-94 V-0 of 1 mm, which is compliant.
