Kuraray Plastics Co., Ltd.
(The Kuraray Group)
Kuraray Plastics Co., Ltd. (Headquarters: Osaka; President: Katsuhiko Kishi) has announced the development of the thermosensitive hose that changes hue according to the temperature of the liquid flowing within it. The new hose will go on sale July 11 (patent pending). The use of this hose will make possible the routine and easy monitoring of liquids as they flow through hoses, which in turn will facilitate highly safe process control. In addition, the color-change allows operators to avoid prolonged exposure of the hose to temperatures outside its recommended temperature range, preventing damage to the hose.
The coil stiffener of this hose uses a fiber containing a special material that changes hue in reaction to temperature change, a fiber Kuraray Plastics developed jointly with The Pilot Ink Co., Ltd. (Headquarters: Nagoya; President: Kenichi Nakasuji), the leading firm in the field of thermosensitive materials. Because the thermosensitive material is colored by mixing the three primary colors, it can display virtually any hue from white to black. The thermosensitivity is functional at temperatures ranging from -10℃ to 60℃, within the range of ordinary manufacturing processes. The hose is designed to change hue when the temperature reaches 0.5℃ above or below its set range.
Varying hue and color allows a number of settings. For instance, a hose that would change colors at 40℃ to indicate the existence of an abnormal condition would behave as follows.
Kuraray Plastics Co., Ltd. is working to develop applications and foster demand from various processing, manufacturing, and agricultural industries in which strict temperature control is needed. The Company is also moving ahead with joint product planning and development to precisely match user requirements.
Standard sizes: 19 to 50mmφ
