The use of polypropylene sheet is very extensive. There are numerous applications for this type of sheets. The sheets are used for the purpose of lining and are also utilized in the manufacturing of tanks used to store acid and chemicals. The sheets of polypropylene are also used in medical field especially in prosthetic industry due to its property that it is very easy to bend and can be molded in different shapes when heated on high temperature. Therefore, the prosthetic industry utilizes these to make shapes that support leg, limb and other parts. Not only these but these sheets are also used in making cladding walls particularly in clean room. The material of plastic manufacturers in Australia has a non-reactive nature due to which it does not perform a chemical reaction with any kind of material therefore it is used in clean room where strong chemicals are used for cleaning and therefore the walls made from these sheets are resistance to chemicals and therefore sustain their structure and maintain their form. Due to this same property these sheets are also quite famous in the manufacturing of the walls of swimming pool. Since the water in the swimming pool consists of chlorine and pressure of water is also variable. Due to these reasons the sheets are best option. Another property of propylene is that these are highly resistance to acid which make them the best suited materials for manufacturing of boxes used to contain the batteries.
There are generally two ways to manufacture these sheets. One way is to make the sheets extruded and the second way is the pressed way. The pressed way to make the sheets are usually planned and the extruded sheets are usually not as planned as the pressed rather than in this process this polypropylene plastic is heated enough so that its temperature exceeds its melting point. When the plastic reaches the melting point then it goes through various number or dices and rollers which changes it shape and flats its surface making it in a sheet like structure. However the pressed way of making these sheets are expensive but the reason due to which it is expensive is that these provide high quality and are more stable and sustainable. In the making of extruded sheets the stress is applied on the sheets which reduces their tolerance capacity and fie to which these are less sustainable.
