Guys,
I verified my dictionary... and in my language "translucent" has similarity with "transparent". But in English, it does not occur. I keep my last considerations, but I change "translucent" for "transparent".
Cheers,

Dear Demon3,
I agree that the chain packing affects density (isotatic PP has 0.9 to 0.91 g/mL). You can see in "Principles of Polymerization" (Odian) that "some polymers are highly crystalline primarily because their structure is conducive to packing, while others are crystalline primarily...
Dear,
Remember that PP is a macromolecule and it has two major shapes: isotatic and atatic (besides the sindiotatic). The first shape of the molecules give to PP the possibility of "packing" it. The consequence is some oppacity in material, because the light is more difficulty to pass through...
Dear,
Maybe the factory want a guy that knows all parameters include in a molding process (temperature, pressure, injection velocity and the extruder velocity, if have a extruder before injector). You know that this things are very important in a polymer process. So, this worker must be able to...
