Thermal Conductivity	W/mK	25oC 400oC 700oC	1.6 2.0 2.4	1.7 2.0 2.4	1.6 2.0 2.4
Heat Resistance	oC	Continuous use Short term	750 800	750 800	800 900
Thermal Shock	oC	100x100x3mm	800	800	550

Note: 
Heat resistance based on deformation up to 1mm of 100x300x3.8mm plate test specimens over a span of 280mm for a continuous heating period of 1,000 hours or 24 hours for short term exposure.
Thermal shock resistance are typical characteristic values determined by heating specimens to the indicated temperatures followed by plunging into water, without any cracking or disintegration.
