Polyvinyl chloride

Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.

PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, signage, inflatable products, and many applications where it replaces rubber.

Pure poly (vinyl chloride) is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.

Discovery

PVC was accidentally synthesized in 1872 by German chemist Eugen Baumann. The polymer appeared as a white solid inside a flask of vinyl chloride that had been left exposed to sunlight. In the early 20th century the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC in commercial products, but difficulties in processing the rigid, sometimes brittle polymer thwarted their efforts. Waldo Semon and the B.F. Goodrich Company developed a method in 1926 to plasticize PVC by blending it with various additives. The result was a more flexible and more easily processed material that soon achieved widespread commercial use.

PVC-1

PVC-1 is a 2007 Colombian drama film directed by Spiros Stathoulopoulos. The plot was inspired by a true story about a pipe bomb improvised explosive device (IED) that was placed around the neck of an extortion victim. This directorial debut premiered at the Cannes International Film Festival in 2007 as an official selection of the Directors' Fortnight. The 84-minute film was shot in one single continuous take without cuts using a Glidecam Smooth Shooter and a Glidecam 2000 Pro camera stabilization system. The film won numerous awards at the International Thessaloniki Film Festival.

Plot

The film, set in Colombia, opens with a gang in a car, carefully looking after a certain package. The gang is led by a violent and volatile man who is only known as Benjamin. A few moments later, the gang arrives at a farm and storm the house, taking the family hostage. Benjamin then says that there is money in the house, and that the family will give it to them if they want to remain unharmed. However, Simon, the man of the house, says that they are wrong and that they are a really poor family who have never had much money. A furious Benjamin holds Simon at gunpoint, while one of his henchmen begins taking measures of all the family member's necks, he realizes that the only person who has the "desired" measures is Simon's wife, Ofelia. The man then takes out the package seen at the beginning of the film and opens it, revealing 2 pieces of PVC pipes and other instruments; he places the pieces around Ofelia's neck and straps them together, forming a "collar bomb". Benjamin then orders the family to lay down on their stomachs, the family complies and, a few minutes later, realize the gang is gone.

Plastic

Generic term used in the case of polymeric material that may contain other substances
to improve performance and/or reduce costs.

Note 1: The use of this term instead of polymer is a source of confusion and thus is
not recommended.

Note 2: This term is used in polymer engineering for materials often compounded that
can be processed by flow.

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organics that are malleable and can be molded into solid objects of diverse shapes. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural.Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.

Due to their relatively low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in an enormous and expanding range of products, from paper clips to spaceships. They have already displaced many traditional materials, such as wood, stone, horn and bone, leather, paper, metal, glass, and ceramic, in most of their former uses. In developed countries, about a third of plastic is used in packaging and another third in buildings such as piping used in plumbing or vinyl siding. Other uses include automobiles (up to 20% plastic), furniture, and toys. In the developing world, the ratios may be different - for example, reportedly 42% of India's consumption is used in packaging. Plastics have many uses in the medical field as well, to include polymer implants, however the field of plastic surgery is not named for use of plastic material, but rather the more generic meaning of the word plasticity in regards to the reshaping of flesh.
