Differences Between Plexiglass & Fibreglass

              

Many people assume that fibreglass and Plexiglass are one and the same thing. In reality, however, these two materials have vast differences between themselves and are also used for distinct applications. The only thing that relates them is the word ‘glass’ at the end of their names. Fiberglass is actually a special kind of plastic made sturdier using real glass, whereas Plexiglass can be best described as a synthetic material developed from polymethyl methacrylate (PMMA). 

It is, in fact, a common brand name for a widely used product made out of acrylic. It has the translucent property of glass and is derived from petroleum. However, it is highly resistant to impacts and very lightweight too, two factors which make it shatter-proof. It is also used for producing a great range of display media and signage by companies specialising in plastic fabrication in Sydney.

This material is generally produced in various forms, with each being designed to suit a particular application. At times, the material is even spun into batting or thin threads. It also serves as a good insulating agent in homes. Other uses involve fibreglass being formed into clothes with different thicknesses and textures in order to be used in fabrication processes. The clothes are first shaped & then combined with resin to harden and form into strong & hard shells.

When it comes to fabrication, determining which one among the two is best depends on how the project requires the material to be manipulated. Once a Plexiglass piece has been bought, it can only be cut to size. On the other hand, fibreglass is extremely flexible as its strips or sheets may be shaped as desired. This why the former is more suitable for making displays and plinths, whereas the latter proves to be very useful for creating car bodies.

Both Plexiglass and fibreglass are highly impact resistant and do not break easily, which make them strong materials. As has been mentioned already, really dense fibreglass is often used for making boat hulls and vehicle bodies. On the other hand, the latter is normally made in different strengths and also treated with various products for supporting the base. It is used for making bulletproof glass as well.

Thus, these are the basic differences between Plexiglass and fibreglass. It is their similarity in appearance and name that cause people to mistake one for the other. But their differences are striking enough to make them suitable for entirely different purposes.
