Management of Chemical Substances in Products

Our stance on PVC, our stance on brominated flame retardants (BFRs) and our stance on Lead (Pb) within plasma display panels (PDPs) all highlight Panasonic's outstanding commitment to the Environment. Indeed, our action on Pb in PDPs and our work towards elimination of BFR in notebooks and mobile phones demonstrates that our commitment to Environmental Protection will often go beyond the stringent requirements of even our own Substance Guidelines.

Panasonic is the first company in the world to achieve the elimination of lead (Pb) in Plasma Display Panels (PDPs) used as the central picture component in its Plasma TVs and Plasma Modules. In this specific case, the use of lead in PDPs was exempt from legislation because no alternative technology existed. But Panasonic persevered and found an alternative.

In conventional manufacturing processes for PDPs, lead oxide glass is used as a key component for the dielectric layer, electrodes, seal frit and other structural elements to form the panel. Until now, lead oxide glass was the only viable technology for this, and as such was exempted under the European RoHS Directive.

Nonetheless, Panasonic dedicated staff and resources to identifying an alternative. In 2006 we finalised our transfer to our new Pb-free alternative, and in November that year, we announced that all Panasonic PDP TVs would use only lead-free plasma display panels.

We have put the following 100% PVC-free models of products^*1 on the market in FY 2009 (as of the end of June, 2009^*2).

• *1 Excluding a resin binder containing PVC-vinyl acetate copolymer (ink, etc.).
• *2 After reviewing a previous table, we deleted four product categories and newly added seven categories.

Also, although halogenated flame retardants are currently essential to protect consumers and to minimise the risk of flammability in some electronic products, we are investigating ways to replace them wherever possible.

Our Components & Devices business group is already manufacturing halogen-free printed wiring boards for certain applications and markets.

Additionally, we have already begun to produce BFR-free products, where it is viable to do so. The table below provides examples of some of our 100% BFR-free products.

In environmental impact assessment, impacts of hazardous substances which are emitted from components containing highly-concentrated brominated flame retardants in inappropriate treatment for collecting rare metals from disposed products such as burning off the field are concerned. On the other hand, although several materials to substitute brominated flame retardants which are used to prevent from fire accidents are developed, some of them are concerned to potentially have impacts to the environment. Panasonic will discontinue the use of brominated flame retardants in case that substitution has become technologically and social-economically available with ensuring product safety.

Some researchers have suggested that phthalate compounds may have toxicity on reproductivity yet a risk assessment report by a Japanese research institute does not recognize such hazard actively. And phthalates are not currently prohibited under any law that applies to chemical substances used in electronics products. In our assessment of environmental impact, Panasonic couldn’t detect the elution of phthalates from materials and components containing PVC, such as coating of cables used in electrical and electronic products, and impacts to human health tabulated from a detection limit did not reach a level of concern. However, some phthalate compounds are prohibited under the toy directives in EU according to the precautionary principles. Since phthalate is mainly used as softeners in flexible PVC plastic, we are trying to reduce or eliminate it for all products by promoting PVC reduction activities.

Antimony is currently essential to protect consumers and to minimise the risk of flammability in some electronic products by using as the anti-flammability assisting agent, primarily as antimony trioxide because it can enhance BFR's flame-retardant effect.

As explained above, we are trying to create more BFR-free products, and we will continue to reduce an amount of Antimony use with the BFR elimination activities.

Panasonic do not produce desk-top computers, but only notebooks. With regards to mobile phones, Panasonic currently only sells mobile phones on the domestic Japanese market, nowhere else.

PVC-free

Panasonic started to selling entirely PVC-free notebook computers (excluding the separate AC cord), in April 2007 in Japan. For mobile phones, all of our mobile phones have been PVC-free (excluding internal wiring in the charger) from FY2005 models onwards.

Furthermore, it is Panasonic's intention to sell only 100% PVC-free notebook computers (including all AC cords etc) as soon as technically possible. We plan to achieve this for new computer models entering the Japanese market in 2009 and by 2011 in the rest of the world (assuming there is no detrimental effect on product quality).

A list of 100% PVC-free products which are currently in markets as of the end of January, 2009 is shown at PVC-free.

BFR-free

With regard to the specific brominated flame retardants PBB and PBDE (including Deca-BDE), we have eliminated these in our computers and mobile phones since October 2005.

Panasonic will never compromise on consumers' safety, and one aspect of safety relates to the non-flammability of our products. This is why we still have to use brominated flame retardants within our computer and mobiles; becausethey assure our products are safe.

However, we intend to eliminate all remaining BFRs, just as soon as we have successfully identified alternatives. For mobile phones, we have already eliminated it from the exterior cases of our mobile phones, and we are diligently investigating alternatives for use elsewhere in the product. It is our intention to achieve this in new models by 2011 (assuming there is no detrimental effect on product quality).

Likewise we continue to investigate BFR alternatives for computers. As such, it is Panasonic's intention to eliminate BFR from all new computers by 2011(assuming there is no detrimental effect on product quality).
