We specialize in heat-resistant insulators and fire-resistant insulants.

Super-heat insulation sheet
(product under development)

Super-heat insulation sheet is a thermally and electrically insulated sheet characterized by lighter weight and better insulating performance than the previous product (D581A).

Characteristics

  1. (1) Super-heat insulation sheet has better insulating performance than the previous product
    (thermal conductivity of 0.084 W/mK).
  2. (2) It is about 25% lighter than the previous product.
  3. (3) It offers excellent workability and can be easily cut, trimmed, or punched.

*Punching may be difficult depending on the product shape. Please contact us for more information.

Applications

  1. (1) Size and weight reduction of insulating and fire-containing products that function in emergencies such as thermal runaway scenarios as well as customer-designed products
  2. (2) Highly thermally and electrically insulated washers and gaskets
  3. (3) Weight reduction of fireproof doors
