K-FLEX materials are flexible, high-tech and effective thermal insulation. The raw material for their production is foamed synthetic rubber, which has closed pores.
Such rubber is produced in the form of sheets or tubes of different diameters, having self-adhesive and protective coatings. Butadiene-acrylic rubber of synthetic origin gives the insulation excellent elasticity, which makes it possible to use it in various fields of industry and construction.
K-FLEX thermal insulation attracts attention with such positive qualities as:
- long service life,
- constancy of technical characteristics over a long period of time,
- good vapor and water resistance,
- very low thermal conductivity,
- maintaining elasticity over a wide temperature range,
- ability to self-extinguish in fire conditions,
- resistance to microorganisms and mold, atmospheric influences.
The operational and thermophysical characteristics of the K-FLEX material allow its use at different temperature conditions (from -200 degrees C to + 150) and in various climatic conditions. High flexibility of the material guarantees good adhesion between surfaces.
The combination of positive characteristics of K-Flex brand thermal insulation ensures ease of installation work and allows for significant time savings when performing work on complex surfaces and in hard-to-reach areas.
Main characteristics
The most important quality of K-FLEX thermal insulation is, of course, its low thermal conductivity, which is ensured by the cellular structure of the products, the small size of the cells themselves, and the optimal volume-to-weight ratio.
K-FLEX thermal insulation has the property of not accumulating moisture during its service life; it has high diffusion resistance to the effects of steam or direct exposure to liquids.
Moreover, its vapor permeability coefficient is of the order of magnitude equal to that of polyethylene film, which is usually used as a vapor barrier when installing thermal insulation.
Among the positive characteristics that k flex thermal insulation has, it should be noted its ability to exclude the penetration of moisture and prevent the occurrence of oxidation processes on the surface of pipelines.
The presence of a fire retardant complex in K-FLEX gives the insulating material the ability to prevent the spread of flame; the material itself also does not support combustion. Thermal insulation K-Flex refers to materials with low toxicity of smoke and combustion products. This makes it possible to use thermal insulation in the construction of facilities with increased fire safety requirements.
The guaranteed service life of materials made on the basis of butadiene nitrile acrylic rubber is 20 years, this data is confirmed by tests carried out by Teploproekt OJSC.
The hygiene of K-Flex is ensured by its inability to emit harmful or unpleasantly smelling substances, fibers or dust during operation. As a result, K-Flex thermal insulation is recommended for use in the construction of facilities with high sanitary and hygienic requirements - schools, hospitals, food production. The thermal insulation does not contain halogenated and recycled carbons, this eliminates the possibility of a negative impact on the ozone layer of the planet.
The economic effect of using K-Flex is obvious - its installation does not require the use of fasteners, installation of an additional layer of vapor barrier and a covering layer indoors. This minimizes installation costs, makes it simpler, and reduces execution time.
