| Remarks:1) If the calculated average of measured thickness is between two thickness mentioned in this table, the values will be acquired by interpolation. If the caculated average of measured thickness is less 0.5mm, the vales will not be over 17mg. If the caculated average of measured thickness is over 25mm, the value will not be over 61mg.2) If nominal thickkness is more than 25mm,it shall be machined to 22.5mm on one side. The machined side should be smooth. | |||||
Packing And Storage
The sheets shall be stored in a place where temperature is no higher than 40℃, and be placed horizontally on a bedplate with a height of 50mm or above.
Keep away from fire, heat (heating apparatus) and direct sunshine. The storage life of sheets is 18 months from the date of leaving factory. If the storage duration is over 18 months, the product also could be used after being tested to be qualified.
Remarks and Precautions for Application
A high speed and small cutting depth shall be applied when machining because of sheets’ weak thermal conductivity.
Machining and cutting this product will release much dust and smoke. Suitable measures should be taken to ensure dust levels are within acceptable limits during operations. Local exhaust ventilation and using the suitable dust/particle masks are advised.
The sheets are subject to moisture after being machined, a coating of insulating vanish is recommended.
