Product application limits are determined by exposure to natural UV radiation. CellTech™ tolerates exposure up to 140 kly/cm2/year, which is equivalent to UV radiation experienced in Madrid, Spain.
Linear Thermal Expansion
When used outdoors, CellTech™ sheets are subjected to temperature fluctuations. The coefficient of linear thermal expansion a (mm/m × °C) for the change in length under the influence of heat is applicable and has to be taken into consideration.
Coefficient of linear thermal expansion ? = 0.08 mm/m × °C
The change in length under varying conditions can be computed as follows:
?1 = 1 × a × ?t (mm)
?1 = change in length (mm)
1 = sheet length (m)
?t = temperature differential (°K or °C)
a = coefficient of thermal expansion (mm/m × °C)
The basic temperature to be used for computing this figure is the installation temperature. An increase in temperature results in expansion; a decrease in temperature results in contraction. Sheet contraction is based on the lowest outside temperature according to the climatic zone map.
CellTech™ will expand and contract depending on fluctuations in temperature. In areas where this product is subjected to 175°F or greater, permanent dimensional damage will result from the softening of the plastics. The use of dark paint or the standard colors other than white is not recommended for outdoor applications. Dark colors have a tendency to absorb more heat, thus increasing the potential for damage.
10, 13, 16 and 19 mm CellTech™ comes in sheet sizes of 48 x 96; 48 x 120 size sheets are available upon request. All CellTech™ sheets are manufactured in a state-of-the-art facility in Huntsville, Alabama.
