Blockage of the bile duct by a cancer, gallstones, or scarring from injury prevents the bile from being transported to the intestine and the active ingredient in the bile (bilirubin) instead accumulates in the blood.
Best Answer: millions of things. Polyethylene is the most popular plastic in the world.It has a very simple structure, the simplest of all commerical polymers. A molecule of polyethylene is a long chain of carbon atoms, with two hydrogen atoms attached to each carbon atom.t is used to provide coatings to paper and paperboard products for packaging of liquids such as milk and fruit juices, and to provide a moisture barrier to paper and woven cloth. It is also used for the coating of foil to provide a heat-seal layer in multilayer film structures.
The combination of polypropyleneâs properties makes it desirable for a broad mix of applications. In many areas where fluoropolymer tubing is typically used, polypropylene tubing can be employed as a relatively low-cost alternative. The high-crystalline composition also makes it good for use in structural systems.Polypropylene (PP) tubing is weldable and, when welded, can be used in non-fluid transfer applications.he combination of polypropyleneâs properties makes it desirable for a broad mix of applications.
