Question: 
What are the main materials in which BPS is found?
Réponse: 

BPS is present in some materials as a monomer, i.e. part of the polymer chain.

 

The main materials concerned are:        

          • BPS-based epoxy resins: coatings in the field of food packaging (tins, drinks cans, etc), automotive and marine industry;

            paints;

            laminated printed circuits (flexible);

            encapsulated semiconductors and structural composites;

             lithographic inks and light-sensitive resins for the electronic industry (this both applications are growing).

 

          • Polycarbonate (*): dishes for canteen kitchens; milk bottles; chocolate molds; water containers; safety glazing; laboratory instruments; medical instruments; housings for household appliances; electrical boxes; broadcasters lighting lamps; CD / DVD, etc.

 

          • Polyethersulfone (*): food industry; hot water systems; dishes for children and baby bottles; electricity and electronics (coils, brush holder, printed and integrated circuits, connectors, fuel cells); automotive industry (parts of carburetors, bearing cages); lighting, optics; medical devices; aviation, aerospace.

 

More discreetly, other materials are also concerned:

           • Polyester resins based on BPS as co-monomer: electricity and electronics, automotive industry, packaging.

           • Phenolic resins based on BPS as co-monomer: electricity and electronics, automotive industry, household appliances, aerospace and aviation, and packaging.

 

On the other hand, BPS can specifically be used as additive for others applications:

          • As additive for the coating of thermal papers (receipts of cash dispensers and receipts);

          • As modifier for leather, fibers, polymers and as hardener for epoxy resins.

 

(*) This material may be produced from others bisphenols than bisphenol S, current uses of this material may nevertheless indicate a potential presence of BPS.
