Dibutylphthalate (DBP)
HP believes other substances should be included in future RoHS legislation. This
includes the restriction of polyvinyl chloride (PVC) and brominated flame
retardants (BFRs) from electrical and electronic products (EEE). HP believes PVC
and BFRs should be the focus for the restriction of chlorine (Cl) and bromine (Br)
from electrical and electronic products, where technically feasible. HP’s reasons
for focusing on PVC and BFRs are:
PVC and BFRs cover 99% of the uses for Cl and Br in electronics;
Given the high percentage usage, these substances have the highest
impact;
Restriction of these substances where technically feasible would
substantially accomplish the goal to eliminate Cl and Br from electronic
products
By July 2007, all PVC and BFRs were restricted
[1]
from the external case plastics
in HP branded products. HP will complete the phase out
[2]
of BFR and PVC in
newly introduced personal computing products in 2011. Unfortunately, it was
not practical in the timeframe of the current RoHS revision for all of the many
types of products (HP and non-HP) in the scope of RoHS to make such material
transitions. However HP believes restriction under RoHS may be possible in
2015, provided that some critical issues can be overcome or addressed by
specific exemptions, including:
For some specific applications technical issues still exist:
–
Electrical performance issues above 1 GHz in Halogen-free printed
circuit boards
Dielectric loss
Unpredictability of technical performance
–
Safety issues in high temperatures areas
Availability issues for environmentally-preferable alternatives
Transition to new substances for high performance products with long life-
cycles
Ability to maintain high recycled content as substances are restricted.
HP is taking a proactive approach to evaluating materials in its products to assess
environmental, health or safety risks. HP may restrict substances because of
customer or legal requirements, or because HP believes it is appropriate based
on a precautionary approach. HP strives to replace legally permitted materials
when scientific data have established a potential health or environmental risk and
lower risk, commercially viable alternatives are available. At HP the evaluation
of alternative materials is a continuous process.
