T-MOLD MS-112 showsexcellent heat-resistance duringlong-term testing at 300℃. Though iti s hard to tell the differ-ence amongt he m a t e r i a ls at 3 00℃ , T -MOLD,retaining its original form,clearly displays heat-resistance at800 to 1,000℃.

What is heat insulating materials？“Heat insulating material”means a material to insulate heat literally. Utilization of heat insulating

material is spreading over various fields from ultra-low temperature applications（-253℃）of usingliquid hydrogen for fuel to high temperature applications（above 2,000℃）that of nuclear reactors.Why do such various fields demand heat insulating materials？ It is because the safety andproductivity improved by the heat insulating materials are necessary for today’s industry. It iswidely recognized that remarkable economic results, improvement of product accuracy as well asproductivity, reduction of energy cost on the production line, comfortable working environmentand minimization of deformation which are all attributed to heat insulation. An increasing numberof industries are expecting more effective heat insulating materials and are taking a great interestin them.

1Types of heat insulating materialsThere are three types of heat insulating materials, i.e.,

solid, liquid and gas, and each of them has uniquecharacteristics. Solid heat insulating materials havevarious types of products that have been developedbased on various materials. As shown in Figure-1, theseproducts are classified as“organic material”,“i n o r g a n i cm a t e r i al”a nd“combined material”composed of organicand inorganic materials. Generally ,“o r g a n ic”h e a t -insulating materials have an advantage in workability andcost, but have problems in durability at hightemperatures. On the other hand,“i n o r g a n ic”h e a tinsulating material is excellent in heat-resistance andstrength, but it tends to be costly.

Nikko Kasei has been conducting diversified andmultilateral researches on heat-insulating materials for along time and pushing forward the development of morepowerful and effective non-asbestos heating insulatingmaterials.

2 Selection and processing of heat insulating materialsIn general, materials are examined by comparing physical characteristics shown in catalogs issued by manufacturers.

However, measuring methods of physical characteristics are not standard and, therefore, the values stated in the catalogscannot be directly compared in many cases. For example, a value of thermal conductivity varies greatly depending on themeasurement method.To avoid troubles in selecting materials, it is highly recommended to consult with manufacturersand processors over and over again.

In most cases, heat-insulating materials are made into flat plate and therefore, cutting, drilling, milling, tapping andpolishing works are required for practical use.The dust generated in the process of such works sometimes causesenvironmental problems. Though Nikko’s products do not contain any harmful asbestos, it is advisable to ask materialprocessors to handle the processing works. The processors authorized by us control the dust and finish up the work withprecise craftsmanship. For further information on authorized processors, please contact our dealers or our head officedirectly.

Notes on processing

Notes on transportation

Install a local ventilator in places where fine chips maybe produced upon processing.Put on any protector to protect yourself from finechips dispersed upon processing.When you complete your work or leave your workingarea, remove the fine chips from your protector andclothes, and be sure to gargle.

1.For heavy materials, use a suitable transportationequipment and handle with care.

Take necessary measures to prevent fine chips from dispersing.For disposal of cut pieces and fine chips, follow your governmental/local rules and regulations and request a qualified industrial wastetreatment contractor.
