PVC Accesories

ASA

The ASA is an amorphous thermoplastic terpolymer consisting of acrylonitrile, styrene and acrylate. The ASA is a plastic called engineering with exceptional weather resistance. Unlike many plastic materials, the ASA maintains its color and impact resistance, even after long use outdoor long term. The ASA is often used for roofs of houses, decks transportation equipment, outdoor equipment and electrical equipment when required persistent color and impact resistance.
The acrylate-styrene-acrylonitrile (ASA) was first introduced around 1970 by BASF under the trade name as Luran S. The intention was to create a similar ABS material but with better weather resistance. Because of this attribute of the ASA, it has been widely used in the automotive industry, as well as multiple applications pool.Guest main trademarks are Luran S and Geloy


FEATURES OF ITS 3 LAYERS

The ASA / PVC sheets are shaped by using the 3-layer co-extrusion technology, which consists of:

  • Surface Layer: This consists ASA resin that is highly resistant to weathering, ultraviolet UV and abrasive effects of           wind.
  • Intermediate Layer: Contains PVC which gives strength and rigidity
  • Bottom Layer: This ASA composite resin white with a high resistance to chemical corrosion which gives durability and colors help maintain the feeling of space and light.
  • What makes it different from the sheets of ASA / PVC compared to other systems of sheets of PVC is its smart ASA resin is that its chemical formulation enables the colors remain bright and not crystallize.
  • Your Benefits are the color fastness, light weight, high stiffness, thermal insulation, sound insulation, strong wind resistance and hail. Therefore the ASA / PVC sheet is ideal for prolonged use in severe corrosive and industrial environments and in areas of acid rain.

Weather resistance OUTDOOR

Excellent weather resistance and gloss retention with exceptional exterior durability. Not only aesthetic but also maintains the mechanical properties under conditions of prolonged exposure to sunlight, moisture and heat.


MISCIBILITY

It can be incorporated in alloys, compounds and mixtures to benefit from the properties of the component resins, for example, Geloy resins mixed with polyvinyl chloride (PVC) for extruded walls, or with polycarbonate resins (PC) for oven applications


TOTAL THERMAL TRANSMISSION COEFFICIENT "U"

The unit of heat flow to complete construction, in which the particles of air and all materials are included Enamble. Is computed by taking the reciprocal of the sum total of all of the resistance "R" of the assembly elements.


R FACTOR (THERMAL RESISTANCE)

The "R", the "Ri" and "Re" factor factor are summed to obtain what the total resistance and "Rt" this way you can calculate the required insulation thickness. To calculate the required insulation thickness of a really "U" is needed. For the "R" factor, which is the inverse of "C" of a material is calculated by dividing 1 / "C" = R = 1 / C


COLOR STABILITY

Modern technology and innovation in the plastics and resins industry gave rise to the ASA / PVC chemical elements combining to transfer all properties to its layers to endow any property maintenance without allowing to color these quickly change their source color avoiding crystallization when exposed to the elements such as UV rays, moisture, heat, cold for a long period, the hardness of the surface layer also prevents friction wind not deteriorate avoiding lost color a given period.

This technology ASA / PVC is the last word in smart technology ceilings.


CORROSION RESISTANCE

With a strong resistance to a variety of acids, bases and salts lamins ASA / PVC are recommended for coastal areas where the abrasive effect of the salt crystals generated by sea deteriorate any superficieo areas that have a high frequency of acid rain .
