How polystyrene foam is made
To make polystyrene first there is need to make the styrene. The styrene is a molecule that is made of 6 carbon and 6 hydrogen atoms. This is made like the benzene.
To make the polystyrene as the name indicate there is poly compound. The styrene is connected into chain by the chemical reactions. The chains are made of specific length to give the soft look to the styrene. When the chain is longer than desired then there will be hard mass formed. When the chain is shorter than the required, foam made will be of less strength and cannot be used as the expanded foam packing.
There is need to make a workable form with the beads so that foam can be made. Beads are made by a sophisticated process known as the periling. The molecules are allowed to sediment in falling position to become a bead. The beads are really good as they will
You will have to make the cubes of the expanded foam packing by the beads made of polystyrene. The cube of foam will be made by combining the beads and then processing them with expanding process. The molecules are expended so they are called expanded foam packing.
When the expanded foam is made in the form of cubes, there is need to make the specific shapes to use the foam for packing. The moulding is done to make the foam ion the appropriate position so that it can be used for the packing purpose. There is the need of making the groove or the sheets are made to make the material good for packing. The moulding in this case is better when done with the heat moulding method. The heat is applied on the foam and the foam will get a shape that is desired.
The packing is done in the expanded foam packing by using the sheets and the moulded foam. The sheets are really good as they can be wrapped around any product and can be used for different length abnormal shape products. The moulded foam is really good for the products that have a regular shape. The box like and shapes that are moulded for a specific product, are really good as they will provide better protection for the products and will not let the products to break.
