Technical Information and Material Safety Data Sheet

 

Transparent vent and cover manufactured from Acrylite® extruded sheet (FF).

 

Characteristics: ACRYLITE® extruded is the highest quality continuously manufactured sheet on the market today. The sheets used for the vent and covers are .060” (1.5 mm) in thicknesses and are protected with polyethylene film or paper masking, which must be peeled off before use. It is a lightweight, rigid and weather-resistant thermoplastic that is dimensionally stable, resistant to breakage and can be easily fabricated and cemented.

 

Safety: ACRYLITE® extruded sheet is more impact resistant than glass. If subjected to impact beyond the limit of its resistance, it does not shatter into small slivers, but breaks into comparatively large pieces.

 

Weather Resistance: ACRYLITE® extruded sheet will withstand exposure to blazing sun, extreme cold, sudden temperature changes, salt water spray, etc. It will not deteriorate after many years of service because of the inherent stability of acrylic resins.

 

Dimensional Stability: Although ACRYLITE® will expand and contract due to changes in temperature and humidity; it will not shrink with age.

 

Expansion and Contraction: Like most other plastics, ACRYLITE® extruded sheet will expand and contract from 3 to 8 times as much as glass or metals. The designer should be aware of its coefficient of expansion and make appropriate provisions. A 48” panel will expand and contract approximately .002” for each degree fahrenheit change in temperature.

ACRYLITE® extruded sheet also absorbs water when exposed to high relative humidity, resulting in expansion of the sheet. At relative humidity of 100%, 80%, and 60%, the dimensional changes are 0.6%, 0.3% and 0.2%, respectively.

 

Heat Resistance: ACRYLITE® extruded sheet can be used at temperatures from -30°F (-34°C) up to +190°F (+88°C), depending on the application. It is recommended that temperatures not exceed 160°F (71°C) for continuous service, or 190°F (88°C) for short, intermittent use. Components made of ACRYLITE® should not be exposed to high heat sources such as high wattage incandescent lamps, unless the finished product is ventilated to permit the dissipation of heat.

 

Light Transmission: Clear, colorless ACRYLITE® extruded sheet has a light transmittance of 92%.

 

Chemical Resistance: ACRYLITE® extruded has excellent resistance to many chemicals including:

  • solutions of inorganic alkalies such as ammonia
  • dilute acids such as sulfuric acid up to a 
concentration of 30%
  • aliphatic hydrocarbons such as hexane and VM&P 
naphtha

ACRYLITE® extruded sheet is not attacked by most foods and foods are not affected by it.
It is attacked, in varying degrees, by:

  • aromatic solvents such as benzene and toluene
  • chlorinated hydrocarbons such as methylene 
chloride and carbon tetrachloride
  • ethyl and methyl alcohols
  • some organic acids such as acetic acid
  • lacquer thinners, esters, ketones and ethers

For a listing of the resistance of ACRYLITE® sheet to more than 60 chemicals, refer to the table.

 

Electrical Properties: ACRYLITE® sheet has many desirable electrical properties. It is a good insulator. Its surface resistivity is higher than that of most plastics. Continuous outdoor exposure has little effect on its electrical properties.
