Super hydrophilic silicone rubber

Silicone rubber surface is hydrophobic in general.
Our original, the world's first new technology can turn it into hydrophilic.

・Little chronological change
Compared with our traditional technology, hydrophilic nature lasts longer, which can make your working process straightforward.

Hydrophilicity lasts after sterilization process which are needed in med/life-science applications.

・Low toxicity
Low toxicity makes this technology support a wide range of applications.

・Life science Fluid management device
Ex)  Preparation of less resistive microfluidic channel Hydrophilic / hydrophobic control on a sheet.
・Material for cell culturing container
Ex) Stress free harvesting by culturing specific cells on an elastic surface, with fluorescent observability.

F-TEM (Flexible-thermoelectric module)

 F-TEM (Flexible-thermoelectric module) is a flexible thermoelectric device by having Peltier elements sealed in rubber.  Basically it can function in the same way as a conventional ceramic Peltier devices.

・ “soft” Peltier device made of conventional Peltier elements and rubber.
・ Flexible (minimum bend radius 25mm) unlike conventional ceramic Peltier devices.
・ Rubber body that replaced ceramics brings a remarkable weight reduction of 40%.
・ Superior drop-resistance (survives against 1.5m free fall impact)
・ Excellent vibration resistance thanks to its rubber body.
・ Comprehensive water tight structure

・ Temperature control
・ Electrically controllable to heat or cool an object
・ Attachable on a cylindrical surface around a diameter of 50mm
