Polycarbonate is a polymer with numerous identical units of bisphenol A which are connected by carbonate –linkages.To transform it into the desired shape and finish,it is melted and forced through a die or in a mold. Polycarbonates are processed through the following main processes:
- Injection molding.the polymer is melted and pressed in to a mold.The hot polymer is cooled to take the shape of the mold.This process is mainly used to manufacture single-end products.
- Extrusion.in this process,the polycarbonate product is melted and pressed continuously through an opening which is referred to as an orifice.This results into a molten polymer which takes the shape of the die.This method is used by most polycarbonate manufacturers to produce large sheets,profiles and long pipes.
The polycarbonate corrugated roof panels are commonly used in most glazing applications since they have a number of benefits.These include:
There are very many variables which include maintenance cost,initial installation cost and the aspect of time.Normally,polycarbonates are more expensive than most glazing materials.This implies that the initial capital for the project will be higher.But what makes it cost effective?
A quality polycarbonate sheet will last for more than ten years while still in good condition and shape.Unlike other plastics which can hardly last for more than 2 to 3 years.Therefore,with polycarbonates,it’s possible to save costs in the long run.Of course,this will translate to more profits.
2.Durability and strength
These glazing panels can be used for virtually any application.They can withstand harsh climatic conditions with fluctuating temperature,resistance to various chemicals and abrasion.They can withstand high magnitude of impact. These are some of the reasons why they are used to construct hurricane barricades.In such environments,it is virtually impossible to use certain products such as glass or acrylic.
3.Design and surface finish
The polycarbonate corrugated roof panels are available in Greca 76, 5.6 waves,profile 7 and softlite configurations, just to mention a few.They tend to combine different properties such as energy saving and better light diffusion properties,energy saving and moderate light transmission etc.The custom made panels whose properties can be manipulated to suit the desired application are also available.
The softlite polycarbonate corrugated panel is an example of a polycarbonate product which blends both the embossed texture and the corrugated structure.That is,as much as it has enhanced strength due to the corrugated structure,it can also diffuse light efficiently.
Did you know that corrugated polycarbonate panels are the most sought for when it comes to greenhouse construction?For instance,the profile 7 is used in most agricultural applications.This because it fulfills nearly all the requirements for any greenhouse glazing panel.These corrugated panels can enhance light diffusion which is a desirable property in any agricultural environment.Thus,farmers can maximize on their production.They have a life span of over 10 years and this will also translate to more profits too.
