PRODUCT OVERVIEW HEAT INSULATION SHEETS
HEAT INSULATION SHEETS
■ Method and Notes for machining Insulation sheet ① When machining, be sure to suck up dust into a dust collector so that it may not scatter. The insulation sheets contain glass fiber. If the dust adheres to eyes or skin or is inhaled or accidentally swallowed, it may affect the human body. When dust attaches to the machine, its accuracy may diminish. ② Drilling holes in the insulation sheet may cause cracks. Attention needs to be taken to hole pitches. ③ T hese insulation sheets are lamination–formed products, and not suitable for tapping and 3–dimensional machining. ● Machining Conditions Lathe Milling Drilling

② Do not use in areas where water 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. ③ When using the insulation sheets (Heat proof) at 300°C or more, there may be some smoke or odor at first, but does not affect the product quality.
