BANNOCKBURN, IL – As a final rule, the US Environmental Protection Agency is prohibiting the processing and distribution of phenol, isopropylated, phosphate (3:1) (PIP (3:1)) in electronics as of Mar. 8.

There are some exceptions to the prohibition: for example, for new and replacement parts for automotive and aerospace industries. However, there are no electronics industry exceptions, says IPC.

The EPA’s final risk management rules to reduce exposure to five persistent bioaccumulative and toxic chemicals (PBTs) went into effect Feb. 5.

PIP (3:1) is used as a plasticizer; a flame retardant; an anti-wear additive; or an anti-compressibility additive in hydraulic fluid, lubricating oils, lubricants and greases, various industrial coatings, and in adhesives and sealants, says IPC. PIP (3:1) is also used in plastic-containing materials that are used to form tubes, harnesses, cables, sleeves, gaskets, and covers of parts – parts used in electrical or electronic products.

IPC seeks member input on the EPA final rule, requesting information on how the final rule may adversely affect supply chains for electronics manufacturers.
