MMA, PMMA, GMA and Spurrs - clarifying nomenclature

From:Gayle Callis

FYI, to avoid confusion on abbreviations

Spurrs is NOT methylmethacrylate (MMA), it is a different, more epoxy like
plastic designed for EM (electron microscopy) generally cut with diamond,
sapphire and glass knives. Specification sheets show the components,
hardeners, etc and it is NOT the same as methylmethacrylate. 

MMA or methylmethacrylate is also known as POLYmethylmethacrylate or PMMA
(MMA and PMMA are interchangeable terms/abbreviations) particularly with
us, the bonehead types. 

GMA = glycol methacrylate, the very chemical name is much longer.  

Each one has is distinct and with their own set of advantages and
disadvantages - another story and discussed at length in the Archives over
the years.
