Technical Information About Acrylic

 

Acrylic is used in a wide range of industries due to it’s technical properties. It is commonly used for Pool Fencing council compliance, display cabinets, police riot shields, signage, fish tanks and aircraft windows and much much more..

 

Acrylic can be formed and molded using heat. It can be cut with either a laser cutter or circular saw equipped with a special blade. Cut edges can be polished using heat, or buffed using a polishing cloth. It can be joined using special adhesives.

 

Acrylic  is made from Polymethyl Methacrylate, or PMMA. It is shatter resistant and half the density of glass.
