A research study to evaluate if the materials HDPE & PET are suitable as cabling ducts for the automotive industry. The cabling ducts will be used in places such as the engine compartment and inside the body of the car. The research study was ordered from Lear Corporation. Lear Corporation uses today a material that is called Polyamide 66 and they wanted the student to find out if it was possible to use either HDPE or PET instead. The reason why Lear wanted it is because the previous report that students from University West did for Lear Corporation shows that the material PET looked surprisingly well. Now Lear wanted to dig in more into depth and see if it was possible to use PET as material for the cabling ducts. Lear choose HDPE also because they wanted the student to compare those two materials and to see if any of those will suit in as cabling ducts. 

Both HDPE and PET are recyclable and environmentally friendly, and the properties (mechanical and thermal) was good. The only reason why HDPE and PET would not work is because they are highly flammable and burns fast. If flame retardant material is mixed with either HDPE or PET, then it will not be recyclable.

The study was completely based on facts and the student have used different databases as well as student literature and previous reports. 

The result showed that the material that Lear Corporation uses today is the most suitable for the combustion chamber and PET suits the rest of the car. Both are recyclable and the process method which is injection molding suits perfectly for PET and polyamide 66.
