Method and Notes for machining Insulation sheet
When machining, be sure to suck up dust into a dust collector so that it may not scatter. Safety measures for usual works in dust, such as masks and goggles, are required as the insulation sheets contain glass fiber which may affect the skin such as itching. When dust attaches to the machine, its accuracy may diminish.
Drilling holes in the insulation sheet may cause cracks. Attention needs to be taken to hole pitches, diameters, and etc.
These insulation sheets are lamination-formed products, and not suitable for tapping and 3-dimensional machining.

Note on handling
Do not use in areas where water, chemical or any liquids may come in. Insulation sheets that has absorbed water can be easily cracked, and cause significant degradation in their performance by increasing temperature.
When using the insulation sheets(Heat proof)at 300°Cor more, there may be some smoke or odor at first, but does not affect the product quality.
Refer to PDF (121KB) for property charts(durability data)on insulation sheets.
