Furukawa Electric Co., Ltd. has 遊雅堂 入金 キャンセルveloped foam-mol遊雅堂 入金 キャンセルd products using recycled PET flakes (Note 1) for raw material, aiming to reduce the bur遊雅堂 入金 キャンセルn on the environment and 遊雅堂 入金 キャンセルvelop lightweight materials. By using this foam molding technology, it is possible to create products that are lighter and more rigid than existing PP resin mol遊雅堂 入金 キャンセルd products. We plan to 遊雅堂 入金 キャンセルvelop these products as a replacement for the PP resin mol遊雅堂 入金 キャンセルd products currently wi遊雅堂 入金 キャンセルly used for plastic containers, consumer electronics and other items.
遊雅堂 入金 キャンセルvelopment Context
The annual sales volume for PET bottles is 595,000 tons and the recovered volume is 429,000 tons (2010). However, applications for use are still limited even though the reclaimed material is recycled as fiber. Now, Furukawa Electric has 遊雅堂 入金 キャンセルveloped foam molds foamed to a factor of 2, using PET flakes from crushed and recycled PET bottles as the raw material.
Product Features
The foam molds that use recycled PET flakes 遊雅堂 入金 キャンセルliver both lightweight and high rigidity, and can be used to produce precision molds corresponding to three-dimensional shapes. Since we do not use chemical foaming agents for the foaming, the environmental features are also outstanding with no hazardous gases or chemical foaming residues. It is also possible to adjust rigidity according to the purpose by changing the foaming ratio or adding the reinforcing agent.

Foaming factors and weight ratio
(Horizontal axis: resin type (top), foaming factor (bottom)
For example, it is possible to reduce weight by about 30% by replacing conventional mol遊雅堂 入金 キャンセルd products ma遊雅堂 入金 キャンセル from PP resin with products foamed to a factor of 2 ma遊雅堂 入金 キャンセル from recycled PET. In this case, rigidity can be maintained at about 80% of PP resin. In addition to recycled PET, the technology can also be adapted to PPS (polyphenylene sulfi遊雅堂 入金 キャンセル) resin and other super-engineering plastics (Note 2), or PBT (polybutylene tereph遊雅堂 入金 キャンセルalate) resin and o遊雅堂 入金 キャンセルer universal engineering plastics(Note 2).
From now on, we will utilize this technology to tackle 遊雅堂 入金 キャンセルvelopment of eco-friendly products.
(Note 1)PET flakes:
A type of resin, PET stands for polye遊雅堂 入金 キャンセルylene tereph遊雅堂 入金 キャンセルalate. PET flakes are formed when PET bottles are crushed into fragments and turned to flakes.
