Bisphenol A (BPA): Properties, Uses and Key Compliance Points for Procurement

Bisphenol A (BPA) is an important bisphenol-type organic compound, appearing as white needle-like crystals at room temperature. It is the key bridge connecting "basic chemicals" with "polymer materials".

Core Uses

BPA is used mainly to produce polycarbonate (PC) and epoxy resins. PC, with its high transparency and high impact strength, is widely used in electronics, automotive lamp covers and sheets; epoxy resins are used in coatings, electronic encapsulation, composites and adhesives. BPA is also used to modify phenolic resins and unsaturated polyester.

Quality Points for Procurement

Industrial BPA is mostly supplied in flake form. When procuring, verify melting point, colour (APHA), iron ion and free phenol content, and pay attention to packaging sealing to prevent moisture absorption and caking. Batch consistency significantly affects downstream polymerisation, so establishing supplier COA comparison files is recommended.

Compliance Notes

Because BPA may migrate under certain conditions, food-contact and infant-product applications are subject to regulatory restrictions in some markets. Buyers should confirm the compliance requirements for the intended end use in advance to avoid grade mismatch.
