Cellular polycarbonate

Mobile or cellular polycarbonate sheet - it is plastic, which is made from polycarbonate extrusion, which involves melting of the granules and extrusion of the mass through a special form, which defines the structure and design of the sheet. Obtained hollow sheets, in which two or more layers of polycarbonate are connected by internal longitudinal ribs oriented in the direction of the length of the sheet.

High ductility and toughness of the material makes it possible to produce sheets extrusion method with very thin walls (0.3-0.7 mm) without loss of shock-resistant characteristics and at the same time, with very low weight. The air contained in the voids between the layers of the sheet, it provides high thermal insulation properties, and ribs - great structural strength relative to weight. Sometimes for the material used the name "structured polycarbonate."

 



We can distinguish the following main characteristics of the product:

 

Ultra high impact resistance (polycarbonate with low weight is 200 times stronger than glass and 8 times stronger than acrylic plastic and PVC).

High thermal resistance (dependent on the properties of small changes in temperature and the critical temperature at which the material becomes brittle, are outside the range of possible operating temperature).

High fire (the material is readily self-extinguishing, and at very high temperatures, material melts but does not allow the spread of flame burning polycarbonate are not accompanied by the release of toxic substances, unlike other plastics).

The extreme lightness, low specific weight (weight of polycarbonate is 16 times less than glass and is 3 times smaller than the thickness of the acrylic similar).

The high insulating properties, low thermal conductivity (heat transfer coefficient - 2.5 W/ m2K, resistance to heat transmission is higher than that of conventional single-layer glass, thus reducing energy costs for heating and cooling by about 30-50% due to the low thermal

conductivity of sheets used in the glazing of buildings, greenhouses, greenhouses).

High light transmittance (transparency - up to 86%, polycarbonate sheets are ideal for applications requiring maximum light transmission, good dispersion of light in a double-pane, the lack of shade, the gain due to the reflection on the partitions).

Good sound and sound insulation.

High chemical resistance (sheets can be used even in harsh environments without changing the chemical composition and properties).

Flexural and tensile.

Excellent weathering resistance (resistance to the most adverse climatic conditions, polycarbonate is suitable for use in the temperature range from-400C to +1200 ° C, a special outer layer protects the sheets against yellowing (degradation) and the wear surface).

Durability, permanence properties (mechanical, optical and thermal properties of the polycarbonate sheets are immutable throughout the warranty period, and even longer warranty period of 10-12 years).

It is possible to handle sheets of specially coated ("Antifog"), which prevents the formation of water droplets on the inner side of the sheet. This coating, which is given to the five-year warranty, durable and resistant to moisture and various chemicals. Lists with this coating is recommended to use in the construction of swimming pools, winter gardens and greenhouses, as by preventing the formation of droplets increases light transmission and reduces the incidence of plants.

Safety glazing (polycarbonate polymer is viscous, so the sheets are made out of it, not broken, do not crack, and, consequently, sharp pieces on impact).

Protection from ultraviolet radiation (a special protective layer applied to the outer surface of

the sheet prevents the penetration of the most harmful to the interior of the UV radiation).

The broad structural features.

The consequence of these features is the ability to create easy, unique and elegant design, to increase the area of the translucent surface by increasing the width of the passage of the bearing structure, to make installation without lifting equipment.

Large format sheets and the ability to bend cold, makes an ideal material sheets to cover the construction of complex geometric shapes: arched, vaulted, and other structures, geometrically complex building projects. Easy handling allows quick and easy installation.

To mount the polycarbonate used special polycarbonate profiles that have the same colors and the same mechanical properties. They are very easy to assemble and create the illusion of seamless construction. Reducing the cost of the object under construction (the use of polycarbonate reduces the total cost of the object under construction, as the light weight sheets to reduce the amount of load-bearing structures).

The table lists the main technical characteristics of the product.

A. In the construction materials used for roofing and vertical glazing of different structures (translucent, enclosing, spherical, etc.):

residential, commercial, industrial buildings and structures

facilities for agricultural purposes

stadiums, gymnasiums, tennis courts, swimming pools

conservatories, greenhouses, conservatories, patios

production of billboards.

4. In the packaging industry:

manufacture of cases for fragile items

manufacture of boxes, protective flight.

The main methods of processing polycarbonate: cutting and drilling.

Store lists of recommended on a flat surface (on a pallet or wooden beams ploschadochnyh) located at a distance of not more than 1 m stack of sheets is necessary to isolate an opaque material to protect them from wind, rain and sun.

In order to polycarbonate has not lost its usability, we recommend periodic cleaning of sheets of water at room temperature with the addition of the detergents used in household (or sodium soap). For cleaning use a sponge or soft cloth. After washing and rinsing plates should be wiped dry with a soft cloth.
