Thermoacoustic Drywall ASA / PVC

what is 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 material to ABS, but with better weather resistance. Because of this attribute of the ASA, it has been widely used in the automotive industry as well to 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, the which consists of:
  • Surface Layer: This consists ASA resin that is highly resistant to weathering, ultraviolet UV and abrasive effects of wind.
  • Middle layer: Contains PVC which gives strength and rigidity
  • Bottom Layer: This consists of ASA 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.







OUTDOOR Weather resistance

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

GOOD RTD

Provides a relative temperature index (RTI) of up to 125 & 176 º F (50 & 176 ° C) and a heat distortion temperature (HDT) of up to 220 & 176 º F (104 and 176 ° C)

TOTAL THERMAL TRANSMISSION COEFFICIENT "U"

The unit of heat flow to complete construction, where the air particles are included all materials and assembly. Is calculated by taking the reciprocal of the sum total of all resistors "R" assembly elements.

R FACTOR (THERMAL RESISTANCE)

The "R" factor The "Ri" and "Re" factor are added up to what the total resistance and "Rt" thus one can calculate the required insulation thickness. To calculate the thickness of isolation required a data "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 elements such as UV rays, moisture, heat, cold for a long period, the hardness of its surface layer also prevents friction Wind not deteriorate avoiding lost color in a given period.

This technology ASA / PVC is the latest rage in the ceilings smart technology.

CORROSION RESISTANCE

With a strong reistencia to a variety of acids, bases and salts in lamins ASA / PVC are recommended for coastal areas wherein the abrasive effect of the salt crystals produced by the sea or deteriorate any surface areas that have a high frequency of acid rain.
