Insulation materials may be categorized (Turner and Malloy, 1981) into one of five major types 1) Cellular, 2) Fibrous, 3) Flake, 4) Granular, and 5) Reflective.
1) Cellular insulations are composed of small individual cells either interconnecting or sealed from each other to form a cellular structure. Glass, plastics, and rubber may comprise the base material and a variety of foaming agents are used.
Cellular insulations are often further classified as either open cell (i.e. cells are interconnecting) or closed cell (cells sealed from each other). Generally, materials that have greater than 90% closed cell content are considered to be closed cell materials.
2) Fibrous insulations are composed of small diameter fibers that finely divide the air space. The fibers may be organic or inorganic and they are normally (but not always) held together by a binder. Typical inorganic fibers include glass, rock wool, slag wool, and alumina silica.
Fibrous insulations are further classified as either wool or textile-based insulations. Textile-based insulations are composed of woven and non-woven fibers and yarns. The fibers and yarns may be organic or inorganic. These materials are sometimes supplied with coatings or as composites for specific properties, e.g. weather and chemical resistance, reflectivity, etc.
3) Flake insulations are composed of small particles or flakes which finely divide the air space. These flakes may or may not be bonded together. Vermiculite, or expanded mica, is flake insulation.
4) Granular insulations are composed of small nodules that contain voids or hollow spaces. These materials are sometimes considered open cell materials since gases can be transferred between the individual spaces. Calcium silicate and molded perlite insulations are considered granular insulation.
5) Reflective Insulations and treatments are added to surfaces to lower the long-wave emittance thereby reducing the radiant heat transfer to or from the surface. Some reflective insulation systems consist of multiple parallel thin sheets or foil spaced to minimize convective heat transfer. Low emittance jackets and facings are often used in combination with other insulation materials.
Another material sometimes referred to as “thermal insulating coatings” or paints is available for use on pipes, ducts, and tanks. These paints have not been extensively tested and additional research is needed to verify their performance.
Insulation materials or systems may also be categorized by service temperature range.
There are varying opinions as to the classification of mechanical insulation by the service temperature range for which insulation is used. As an example, the word cryogenics means “the production of freezing cold”; however the term is used widely as a synonym for many low temperature applications. It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins. The National Institute of Standards and Technology in Boulder, Colorado considers the field of cryogenics as those involving temperatures below -180 C. They based their determination on the understanding that the normal boiling points of the so-called permanent gases, such as helium, hydrogen, nitrogen, oxygen and normal air, lie below -180 C while the Freon refrigerants, hydrogen sulfide and other common refrigerants have boiling points above -180 C.
YarQuenXer, Melamine foam, manufactured by SINOYQX, is able to be used for industrial and household thermal or heat insulation materials, thanks to its strong thermal insulation property, stably within -180℃~200℃ for a long time at 240℃ for a short time, meeting DIN 4102-1, DIN 5510-2, UL84, ASTM E 84 class A, and low thermal conductivity of less than 0.035 W/(m*K) and the resulting excellent thermal insulation performance, but light-weight, free-fiber, non-toxic, easy post-processing, etc.
YarQuenXer Melamine foam can be used in thermal insulation for pipis and household, such as solar panel thermal insulation, hot water tank insulation, etc, and other insulation applications and noise reduction for air-conditioning and ventilation system. It can be made to soft wall board and wall-insulation board, etc.
YarQuenXer Melamine foam is designed to be thermal and sound insulator for car, motor, train, etc engine mat and car engine cover from its all-round sound absorption, thermal insulation performance, fire-resistance, chemical resistance, and light-weight, via post-processing with alum foil and non-woven fiber etc.
