Basfiber® has good electric insulation. Its volume electrical resistance is higher in order of Magnitude than E Glass fiber. Basfiber® contents the conductive oxides less than 20%. This electric oxide is not made use as the insulation material but after the special treatment with sizing, its dielectric loss angle is lower 50% than Glass fiber and can be used as the novel heat & electric resistance.
The most effective way to reduce the loss of heat energy is good insulation. Regardless of the use of structural and technological solutions you would like to use light, durable and harmless product. These are the characteristics for different types of thermal insulation chambers (ovens, sterilizers, etc.) have a fibrous insulation materials used in conjunction with the reflective insulation (foil).
By the fibrous insulation materials, have received widespread industry should include fiberglass, and more recently, such Eco - Innovative product as Basfiber®, which is due to the introduction of modern technologies to reduce the cost of its production and quality are increasingly being used in various industries.
Basfiber® is produced from natural mountain magmatic rocks gabbrobazaltovogo types: basalt, diabase, gabbro, amphibolite, andesite by melting the material at a temperature of 1400-1500°C, and blowing up a high-temperature 1600°C With high gas flow ( 300-400 m/s) at discrete basic staple fibers.
Basfiber® insulation of the super modern materials are the twenty-first century, combining ecological purity, natural durability, fire safety (incombustible). Temperature range of application of basalt fibers ranges from -260°C and 900°C, while the glass of -60°C to 450°C, hygroscopic basalt fibers less than 1%, glass - up to 10-20%.
Producing industrial glass fiber especially in the neutral composition can absorb significant amounts of moisture in the humid air. This affects their physical and technical properties and durability and eventually leads to destruction of fibers.
Basfiber® fibers absorption is low not changing over time hydroscopicity (0,2-0,3%), due to its chemical composition, provide thermal stability characteristics in the long run, have high chemical resistance and belong to the first hydrolytic class, and on acid and alkali steam resistance is far superior glass fiber.
The disadvantages of glass fibers in comparison with Basfiber® is a low temperature of +450°C and the sintering temperature 600°C, thorniness threads and the allocation of fine dust by mechanical destruction of the insulation during thermal-cycle loads. The strength of Basfiber®, due to the high modulus of elasticity is 35-40% higher than the strength of glass fibers - the fiber is more elastic, unarmed.
Materials of Basfiber® have a much greater resource exploitation, as compared with the materials of glass fibers. Fibers from Basfiber® is firmly fastened together by natural cohesion. In mineral waddling for instance, and glass fibers are used for gluing and carbamid phenol-formaldehyde resin, the concentration of vapour in the air of working area should be strictly controlled.
