A review of all the polymer processing technologies and their capability to produce enhanced properties through combining different polymers.
A review of the current and novel polymers available for the use in co extruded and multilayer structures.
How a structure can be designed for packaging, construction, automotive and medical applications.
Properties of various barrier polymers
A comparison of the properties for various barrier polymers with an extended evaluation of the properties of EVOH for different applications.
Forming multilayer polymer melts
The many types of extrusion dieheads are reviewed and the possibility of forming multilayer structures examined. The rheology of different materials is reviewed in relation to the principles of die design. Examples of theoretical modeling are provided.
The implications of using multiple extruders is examined and the requirements made for control and ancillary equipment.
Quality and process control
How to be in control of the process and product for multilayer structures with practical SPC examples demonstrated. A practical case study is given for obtaining multilayer pipe to customer standards. Start up and shut down procedures are given.
Possible faults and trouble shooting
The instabilities due to using multiple layers are considered. Potential defects in products are examined and linked to the end physical properties and quality control.
Time is given to delegates in the final part of the course to discuss their own specific application areas with Dr. Peter Cox.
This course will concentrate on structures and processes for blowmoulding and manufacturing pipes/tubes from 1mm in diameter, for medical applications, to large bore pipes. A practical case study examines how to obtain multilayer pipe to customer
