Polypropylene (PP) mesh is currently used in both hernia and pelvic organ prolapses, but may not always be the most biocompatible option. Mesh implantation will naturally generate an inflammatory response to the inserted mesh, but biocompatibility ranges from how easily it is integrated to how severe the foreign body reaction is.
Polypropylene has been used in hernia and pelvic organ prolapse repair operations to protect the body from new hernias in the same location. A small patch of the material is placed over the spot of the hernia, below the skin, and is painless and rarely, if ever, rejected by the body.
A polypropylene mesh Prolene product is used for repairing hernias and other injuries to the fascia. Prolene commonly is used in both human and veterinary medicine for skin closure. In human medicine it is used in cardiovascular, ophthalmic and neurological procedures. It is often used in conjunction with the absorbable suture Monocryl.
Polypropylene manufacturers consume nearly two thirds of global production. [17] Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used for the production of important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In the year 2013 about 85 ...
Polypropylene sheets are used for stationery folders and packaging and clear storage bins. Polypropylene is defined by the recyclable plastic number 5. Although relatively inert, it is vulnerable to ultraviolet radiation and can degrade considerably in direct sunlight. Polypropylene is not as impact-resistant as the polyethylenes (HDPE, LDPE).
Used in the field of cryogenics: Twaron: Para-aramid: Heat resistant and strong fibre: Bullet-proof body armor, helmets, brake pads, ropes, cables and optical fibre cables, etc. and as an asbestos substitute Mylar: Polyethylene terephthalate film: High strength and stiffness, less permeable to gases, almost reflects light completely

The PP and PE components of a blend constitute the "crystalline phase", and the rubber and branched PE chains and PE/PP end groups gives the "amorphous phase". If PP and PE are the dominant component of a TPO blend then the rubber fraction will be dispersed into a continuous matrix of "crystalline" polypropylene.
