-Perfect: After 30 days of continuous contact with chemical material no change is observed
-Good: After 30 days of continuous contact with chemical material no damage or small damage is seen
-Medium: After 7 days of continuous contact the solvent can soften and inflate acrylic sheets
-Bad: It’s not suitable for continuous contact

 

Applications:

Acrylic sheets have superior properties in change of environmental temperature, are resistant to change of climate, have less percentage of moisture absorption in comparison to normal glass, are more resistant  to heat shocks in comparison to glass and if broken they don’t have sharp or acrid surface. Some of its usages are as follows:

-Industrial Use, Security Covering & Rooms, Coatings of Stores, Transparent Pipes, Transport Industry
-Skylights and False Walls
-Advertisement Boards and Partitions
-Office and House Decoration
-Public Telephone Booths and ….
