There are collected information about processing of the polymers and composites.
Saying easier: How to do something from polymers and composites.
One of the most impressive type of extrusion is blow film extrusion, a combination of extrusion and blowing which allows to produce a tube of thin plastic film. Continue reading
We already know what is happening inside our garden plastic furniture during summer time. But what kind of effect can occur when plastic is exposed to the sun and how to prevent those changes. Continue reading
Next process, extrusion, is popularly used in the plastics industry. This is a machinery process where raw plastics are shaped into ribbon or other desire profiles. Continue reading
Have you ever noticed how plastic furniture changes its colour when exposed to the sunlight? I am living in Spain, so I can observe this effect everyday. Continue reading
Increasing number of wasted polymers forces changes in the polymer’s synthesis process. Currently, the production of the biodegradable plastics presents a strong trend. Continue reading
Injection moulding is one of the most popular manufacturing processes, used for fabrication of plastic parts. The plastic parts, produced by this method, can have variable shapes and sizes. Continue reading
Do you know what is a polymer degradation?
I suppose that everyone who was working with polymers met this term. I suppose that some of you can even have nightmares. Continue reading
Nowadays there are three very common terms: degradation, biodegradation and composting, but what are they and what is the difference between them? Continue reading
Recycling is a very important process for ours and next generations’ lives, because it gives a big chance to have a normal life in a natural (not too much destroyed) environment. Continue reading
Processing is a process (yep, it is), where a material changes its shape to the shape we want. But how to do this? There are a number of methods to reshape things, such as hammering, breaking or molding.
But how to do it with a plastic? We can not just break it or push it to change its shape. Fortunately, there are a lot of ways to change a plastics shape permanently, but mostly all the methods are based on the same principle.
That is, we have to change the state of the material and then with a help of some tool, create a new desirable shape. The state can be changed by using heat, pressure or both at the same time.
In the liquid state (or semi-liquid state) the plastic material has to be in the tool, which has the desired shape. Then, by cooling down, the plastic changes the state again, but this time from liquid to solid. This way the new shape of the plastic has been achieved.
Simple, isn’t it?
