BSEF around the World: BSEF China takes part in the 2019 International CPCA (Shanghai)

From March 19 to March 21, the International Bromine Council (BSEF) participated in the 2019 International CPCA (Shanghai) Show, with the theme of its exhibition stand “Flame Retardant Expert of Printed Circuit Board– TBBPA”.

Over 250 visitors dropped by the BSEF booth and nearly 100 participated in our questionnaire.

TBBPA is the best choice to ensure PCB to reach the fireproofing grade V0 of UL94. As an important flame retardant substance which can be developing in a continuous way, TBBPA will never constitute a threat to people’s body health and the environment in the major application fields. 90% of TBBPA is used as the reactive fire retardant (producing brominated epoxy polymer) to apply to the printed circuit board of the electronic and electrical appliance. In that process, TBBPA will never exist in its original form through covalent binding or being “reacted” to the polymer matrix. As a result, TBBPA hardly has no potential to be discharged to the air. Lower than 20% of TBBPA is used as raw material of brominated low polymer and polymer (covalent binding) and as the additive flame retardant of ABS plastics. In this process, it is sealed in the polymer matrix so that it is not likely for people to contact with it.

In late 2013, Canada published the filtering and assessment report on TBBPA, indicating that TBBPA has a negligible influence on human health. In 2011, the European Food Safety Authority (EFSA) published the result of a study on the risks of the TBBPA and its ramification exposure to food, showing that “the amount of the TBBPA exposed to food in the EU will not trigger the concern about health”.

According to the result of an eight- year risk assessment of the TBBPA issued by the EU in 2008, the TBBPA causes a lower environmental risk which can be controlled.

Under EU RoHS, the European Commission launched an assessment of TBBPA in early 2018 and planned to finish it in late 2019.
