Materials
-
Plastic extrusion allows a wide range of plastic products--including drinking cups, toys and machinery parts--to be made from acrylic, acrylonitrile butadiene styrene (ABS), polystyrene and polyvinyl chloride (PVC).
Applications
-
Tubing extrusion is used in many applications, from film manufacturing to protective packaging. Co-extrusion, which creates plastic layers of varying thickness, is used for doors, windows and automobiles. Specialised extrusion techniques are also increasingly being applied in the pharmaceutical industry and in the manufacture of fuel cells.

Latest Developments
-
According to the Frost & Sullivan Research Service, the rising price of crude oil--from which the raw materials for plastic extrusion are made--has led to innovative technologies within the plastic extrusion industry. Extruder screws are continually being improved, so that they produce higher output at low discharge temperatures.
