| Sony Chemical & Information Device Corporation has been introducing solventless methods and alternative solvents into our manufacturing designs and production processes in order to reduce possibly hazardous chemical substances in its products manufactured with the use of specific solvents and chemicals for raw materials. | |||
Typical environmentally conscious products |
|||
1. Halogen-free products |
 |
Halogen-free flexible flat cables F2000 and F2100 Sony Chemical & Information Device Corporation pioneered development of the halogen-free flexible flat cables in 1998, which are now widely used in wiring in devices such as PCs, audio-visual appliances and game machines. Antimony was also eliminated along with halogens. F2000 produces no dioxins when incinerated. |
 |
Halogen-free 2 layer polyimide circuit boards Proprietary technologies, including polyimide-coated copper foils, allowed elimination of the conventional adhesive layer and thus of halogens. Products such as halogen-free COF, COF-TAB and Bridge Flex Circuits for HDD are based on this 2 layer polyimide circuit board. |
 |
Halogen-free build-up and Flex-Rigid printed circuit board High-density build-up and Flex-Rigid printed circuit board were made halogen-free by improvements in materials and pigments for solder resist. The preflux needed in soldering was switched from the conventional, possibly hazardous organic solvent-based type to water-soluble, heat-resistant type that generates less gases. |

Halogen-Free Self Control Protector (SCP) In 2008 we commercialized halogen-free type self control protector (SCP), a surface mounted type fuse that interrupts overcharge or overcurrent in Li-ion rechargeable batteries. |

2. Products with UV curable manufacturing method |
 |
Double coated tape G9000 Adhesive tape with lower environmental impact with UV curable manufacturing method, was first marketed in 1997 as Green Tape G9000 series. Since then new types with improved resilience to curved surfaces, impact resistant and recyclability were launched, which have widely been used in electrical appliances and industrial machines. |

Approach that promotes circulation of resource |
Product environment initiatives are underway with Sony recording media products manufactured at the Tagajo Plant with the focus on reduction and recycling.
[ Reduce ]
1.Reduction of plastic used in existing Blu-ray disk cases for business use by approximately 5% and of plastic used in LTO cases by approximately 17%.
2.Discontinuation of use of individual packaging cases in a cartridge containing ten LTOs and change to a packaging format that eliminates the need to unpack disks, realizing improved convenience for the customer at the same time.
3.Design review of cardboard cushioning material for consumer Blu-ray disks, achieving further reduction in consumption.
4.Changing cushioning material for products from urethane to cardboard.
[ Recycle ]
1.Coloring of consumer Blu-ray disk cases was discontinued, while prioritizing ease of recycling and implementing display of materials used in displayable plastic components.
2.Use of highly recyclable cardboard as packing material and use of recycled paper for cards used with products to realize resources recycling.
