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.

Company information
Our company is a manufacturer specializing in the processing of resins, ceramics, and insulation materials. We receive drawings from customers, procure materials either in-house or supplied by customers, and use machining centers, NC lathes, and other machine tools to process various resins, ceramics, and insulation materials, producing components for the manufacturing industry, such as machine parts and electrical insulation parts. The main features are as follows: 1. While we handle a wide range of resins, ceramics, and insulation materials, we particularly excel in processing materials that are difficult to work with, such as: (1) Composite materials of resin with glass fiber or carbon fiber (FRP, GFRP, CFRP) (2) Insulation and heat-resistant materials (rigid insulation boards primarily made from glass fiber, cement, mica, etc.) (3) Ceramics (4) Carbon 2. Since we deal with a wide range of resins, ceramics, and insulation materials, we can supply most materials. 3. With various machines such as machining centers, NC lathes, grinders, and gear cutting machines, we can manufacture most shapes. 4. We can accommodate production quantities ranging from one piece to 50,000 pieces. 5. We keep a stock of materials, allowing for short lead times. 6. We understand the characteristics of various resins, ceramics, and insulation materials, enabling us to select the optimal material according to requirements. 7. We can ship nationwide.
