Dicopesa cast acrylic sheets 

Dicopesa cast acrylic sheets are made with high quality Methyl Methacrylate, and produced in such a way to assure excellent properties to different applications such as:

-  Superior resistance to glues and solvents commonly used on processing Acrylic Sheets.

Cast acrylic sheets long life to your sign.

- Reduced residual monomer content, making it adequate to use in medical and nursery applications.            

Medical equipment requires educed residual monomer content.

                                    Properties of the cast acrylic sheets

On this section, below, there is some short information on the properties of the cast acrylic sheets. The data given herein are solely for orientation, is not guarantee implied.

a)  Light transmission.

Acrylic Sheets can reach as much as 92% of transparence, more than any other material on this aspect.  

b) Impact resistance.

Cast acrylic sheets are tem times more impact resistant as compared to glass on the same thickness. They can be a useful alternative where impact resistance is needed, also when security is an issue.

Acrylic sheets are ten times more impact resistant than normal glass.

c) Weight 

Acrylic sheets are 50% lighter than glass and 43% lighter than aluminum at the same thickness.

d)    Acoustic insulation

The table below shows the reduction that can be obtained at different thickness and sound frequency. The measurements are presented in decibels.   

Obs.: One can obtain 3 to 5 db more by using double wall with an air camera in between.

e)    Expansion coefficient

Acrylic sheets expand and contracts more than the majority of materials used in construction, though less than most of the plastics. The table below compares the expansion coefficient of cast acrylic sheets with aluminum and glass. Therefore, when using acrylic, enough room shall be installed to allow expansion and contraction of the material. 

Values : cm / cm / ºC

f)    Rigidity

Acrylic sheets are less rigid as compared to glass or aluminum, and can bend if submitted to weight. This must be taken into consideration when using the sheets.

g)    Load in use

Acrylic sheets will not stand over 100 Kg/cm2 of load. A crazing (surface cracking of the material) will appear if such limit is exceeded.

h)     Working temperature

Acrylic Sheets can be used from 40 degrees centigrade below zero (minus 40 Fahrenheit), until 80 degrees centigrade (176 Fahrenheit) above zero. It is useful for refrigeration and freezing applications, provided care is taken about expansion and contraction.
