Product Descriptions

A coating layer maintains the heat-resisting property under high temperature environment (maximum 320 °C) unlike the general heating paste.
Temperature elevation rate of the AccuPasteTM is faster than the sheath heater, which is the existing nichrome line type, and electric efficiency is excellent from at low voltage.
The incidence of air pollution, the noise, and electromagnetic waves is low due to using a radiant heat of CNT paste.
Application field of AccuPasteTM heating paste can be classified with the heat generation material based on high heat conductivity, the ESD/EMI shielding material based on electric conductivity, and transparent conductive film for touch screen.
The heating apparatus can be manufactured with the AccuPasteTM, which has an excellent performance. And also it is able to manufacture a premium class product of a high-level and slim design.
There are difficult to implement high performance heating apparatus due to the limitation of the existing materials, so the demand for high-performance new materials is increased. AccuPasteTM will meet these requirements.

Applications of AccuPasteTM Heating Paste































The Features of AccuPasteTM Heating Paste

Coefficient of thermal expansion of CNT nano-materials are lower than other materials (Coefficient of thermal expansion : -2 ~ +5 X 106K-1), and dimensional stability is excellent.
AccuPasteTM heating paste has a high stability for the most chemicals and solvents.
There is no biological infringement or blazing fire.
AccuPasteTM heating paste has a protective function for electromagnetic waves, because its occurrence strength during heat generating is low level that do not affect in a human body.
The high heat conduction and the far-infrared radiation ability are possible heating of the wide space by instantaneous heat generating and far-infrared radiation.
Far-infrared has a physiological activity effect because of the resonance effects through water molecules existing in the living body.
The high heat conductivity is usable to electronic material or heat material for industry.
AccuPasteTM heating paste has low sheet resistance (76 Ω/ㅁ) at 10 µm of coating thickness.
