Successful Substitutions

Borealis has substituted hazardous chemicals since the beginning. This has been an even greater focus since 2008, when the Company published the first Borealis Banned substances List. Since then, Borealis has successfully phased out several substances. Here are some example success stories, which will be updated with more recent examples on a regular basis.

Dechlorane Plus (CAS# 13560-89-9) – Global phaseout after SVHC status in EU

'Dechlorane plus' (1,6,7,8,9,14,15,16,17,17,18,18- Dodecachloropentacyclo[,9.02,13.05,10]octadeca-7,15-diene) was used by Borealis compounding facility in the US as a flame retardant in two products. These products were dedicated for very specific cable applications that demand compliance to the very high fire protection standards in the US. In the EU, the chlorinated flame retardant Dechlorane plus was added to the REACH candidate list of substances of very high concern (SVHC) for authorisation in January 2018. The reason for the addition was its vPvB (very persistent and very bioaccumulative) properties. Borealis policy is to strive to limit the use of identified SVHC, accordingly the Energy business department decided to phase out the two concerned US products. They were discontinued by the end of 2018.

Decabromodiphenyl ether (DecaBDE , CAS# 1163-19-5) - Phased-out four years before its addition to the REACH candidate list

Decabromodiphenyl ether (DecaBDE) is a UL-listed flame retardant. In the US, flame retardation must meet building code requirements and Borealis therefore used the substance as a flame retardant for wire and cable insulation compounds. In 2008, Borealis substituted DecaBDE in anticipation of a voluntary agreement between the big manufacturers in the US and the Environmental Protection Agency (EPA). In collaboration with its supplier, Borealis found a less hazardous new brominated flame retardant that fulfilled the UL standard.

In Europe, DecaBDE has been restricted by the EU RoHS Directive since 2002. It was added to the REACH Candidate list of SVHC for authorisation in 2012, for its persistent, bioaccumulative and toxic (PBT) properties. There is a restriction proposal under debate that would effectively mean a full ban for the substance, apart from certain spare parts and uses in aircrafts.

Although DecaBDE is still allowed in the US, the implementation of the Toxic Substances Control Act means that DecaBDE is likely to be one of the first priority chemicals to be assessed and regulated by the EPA.

Tris(nonylphenyl)phosphite (TNPP,– CAS# 26523-78-4) - Phased out in 2010, years before it entered CoRAP process

Tris(nonylphenyl)phosphite (TNPP) was present as an antioxidant in the external resin used in Borealis compounds intended for fish packaging. There was growing concern in the market and among the public that the substance would be persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB). Borealis found an alternative material on the market containing a less hazardous antioxidant, which was evaluated not to be PBT/vPvB by a member state's competent authority. Borealis stopped using TNPP in 2010.

TNPP containing > 0.1% of 4-nonylphenol, branched and linear, has recently been added to the candidate list of SVHC.

Nonylphenolethoxylate (NPE, CAS# 127087-87-0) - Replaced despite very low concentration in final product

Nonylphenolethoxylate (NPE) was used as a surfactant in one of the supplied polyolefin additives. The final concentration in Borealis' products was less than 10 ppm. In 2013 Borealis fully replaced NPE, which had come under increasing pressure from NGOs and authorities (in particular the European Chemicals Agency and the US Environmental Protection Agency) for its endocrine disruptive (ED) properties. As a consequence, Borealis approached its supplier, which was eventually able to substitute it with a less hazardous surfactant. In addition, Borealis found other suppliers that do not use any surfactant for an equivalent product.

In the meantime, NPE was added to the REACH authorisation list (Annex XIV) with a sun-set date in January 2021 for its ED properties. There is also an EU-wide restriction published, restricting the use of NPE in textiles from 2021 onwards.

Crystalline silica as antiblock agent in PE film (CAS# 60676-86-0)

Crystalline silica was used as an antiblocking agent in some PE film grades. In 2010, Borealis replaced it with amorphous, synthetic silica for this use. The International Agency for Research on Cancer had found it to cause cancer when inhaled.
