Mica-based insulation board Danma 550L Danma 700L machining
Insulation boards with excellent heat resistance (550L: 550°C, 700L: 700°C) and high strength, suitable for use as structural materials. They also have excellent electrical insulation properties.
DANMA 550L and DANMA 700L are materials that accumulate flake-like micro mica pieces and are integrated with silicone adhesive, possessing heat resistance, thermal insulation, and electrical insulation properties. <Features> 1. Excellent heat resistance (550L: 550°C, 700L: 700°C). 2. Due to the lamination effect of mica flakes, the bending strength and compressive strength are several times stronger than general insulation materials, allowing for use as structural materials. 3. Superior electrical insulation, arc resistance, corona resistance, tracking resistance, and dielectric strength. 4. Machining such as cutting, milling, grinding, and drilling is possible. <Applications> 1. Insulation material for electric furnaces, induction heating furnaces, and arc furnaces. 2. Insulation material for dryers and incinerators. 3. Insulation material for injection machines (injection molding machines) and rubber vulcanizing machines. 4. Insulation material for heat presses. 5. Electrical insulation material for high temperatures. <Material Dimensions> Thickness: 0.2 to 30 mm Size: 500 x 1000 mm sheets and boards Material Manufacturer: Okabe Mica Industry Co., Ltd.
