*2 Most sheets are made by 1.0 mm or 0.5 mm order (1.0, 1.5, 2.0 mm etc). But some of them are not in production.

*3 Hardness (Asker C) is measured on JIS K 6523. 2 datas are checked, 0 second and 15 seconds after measurement. Upper figure means 0 second, Lower figure in ( ) means 15 seconds data.

*4 Temperature range is measured by hardness change, etc. and flexible depending on conditions.

Test method of thermal performance

1. Thermal resistance

Thermal resistance is measured with device as below, for 10 min and 12W heating value.

[Formula] Thermal resistance (℃/W) = (Object temp - Heat sink temp) / Voltage 12V

TM sheet is sandwiched between Heat sink and Object (9.63m2), and tightened equally. After heated for 10min with 12W, temperature of both Heatsink and Object (T1 and T2) are measured. Thermal resistance (R1) is calculated by assigning these temperature into the formula.

Total thermal resistance=thermal contact resistance of Heatsink+ thermal resistance of Sheet +thermal contact resistance of Object

2. Thermal coductivity

Thermal coductivity is measured based on JIS-R2616 with measuring instrument made by KYOTO ELECTRONICS MANUFACTURING CO., LTD. Over 10mm thickness is needed.
