Note: The thickness listed above is the average of test results. Sheets with thickness between the two thickness listed above, the water absorption shall be obtained by Interpolation Method. Sheets thinner than 0.5mm, the values shall be the same of the 0.5mm sheet. Sheets thicker than 25mm shall be machined to 22.5mm on one surface before experiment.

Packing and Storage

The sheets shall be stored in a place where temperature is no higher than 40℃,and be placed evenly on a pad with a 50mm or above height.

Keep away from fire, heat (heating apparatus) and sunshine. The storage life of sheets is 18 months from the date of dispatch. If the storage life is over 18 months, the product can still be used provided being tested to be qualified.

Remarks and Precautions for Handling and Use

A high speed and small depth of cutting 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 use of suitable dust/particle masks is advised.
