Aspects and applications of polymer extrusion

摘要

Polymer manufacture today is one of the most important worldwide industrial sectors and,significantly,is not confined in the centre of manufacture to one or two highly industrialised nations.In contrast,a large number of diverse nations have resources that are based on a variety of raw materials,including rubber,crude oil and recycled materials.Associated with this,many countries also have a large capacity for polymer production.Clearly,an industry such as this cannot easily be summarised and no two polymers are produced under exactly the same processing conditions.
