Mitsui Chemicals, Inc. (Tokyo: 4183; President & CEO: Tsutomu Tannowa) has revealed the sixth project under “Material Meets Creative Team”, a creator-based collaboration project that aims to promote the appeal of materials from an all-new perspective. For this latest project, Mitsui Chemicals Tohcello, Inc. (Representative Director & CEO: Takeshi Kaide) collaborated with Taku Sasaki, a member of KOKUYO CREATIVE CENTER, using a newly-developed material by Mitsui Chemicals Tohcello - Shape Memory Sheet. The collaborative effort resulted in the creation of “UNFRAGMENT” – the vase that’s already broken.

The Shape Memory Sheet offers flexibility, shape memory, stress absorption, low repulsion and a range of other characteristics. Further, the material’s temperature dependence makes its firmness susceptible to change, especially at normal temperature ranges. This then gives the material an all-new feeling of suppleness and flexibility, which has been highly evaluated on multiple fronts.
When used to create UNFRAGMENT, the material’s shape memory characteristics provides the product the ability to return gradually to its original shape. The resulting product pays homage to the traditional kintsugi technique of fixing broken pottery to bring new value. When the vase is spread by the human hand, the vase will gradually returning to its original shape over time. UNFRAGMENT expresses a product timeline like nothing else before.

Shape Memory Sheet

The Shape Memory Sheet, a new product developed by Mitsui Chemicals Tohcello, takes a special Mitsui Chemicals polymer, foam it, and turning it into a sheet. A wide range of people have gave high evaluation, particularly for how the material feels to touch.

Becoming more flexible from normal temperatures, any part of the material that is held grows softer, while other parts remain somewhat harder. This then produces the feeling of support by the material. The Shape Memory Sheet is garnering attention for its contributions to product development, and can be applied to suit consumers in the health care, medical, nursing, sports, seating, cushion and other such sectors.
