N-methyl-2-pyrrolidone 872-50-4
>85% of compound
N-methyl-2-pyrrolidone (NMP) is a cyclic organic compound made up of carbon, nitrogen, and hydrogen.
25
Carbon
Carbon- (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent
bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table.
26
Nitrogen
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It
is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
27
hydrogen
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass,
and renewable power like solar and wind

Polyvinyl Chloride
Polyvinyl chloride (PVC) is made from a polymerized form of vinyl chloride monomer (VCM), which is created by combining ethylene (derived from oil or natural gas) and chlorine (derived
from salt) through a chemical reaction; essentially, PVC is made from a combination of oil/gas and salt.
Polyvinyl Chloride (PVC) is one of the most widely produced thermoplastic polymers in the world after polyethylene and polypropylene. Without the additions of plasticizers, PVC is a
naturally white, brittle plastic.
30
Polyvinyl Chloride resin
uses
PVC is primarily produced as a rigid or unplasticized polymer (RPVC) or as a flexible plastic (uPVC). Flexible, plasticized or regular PVC is softer and more amenable to bending than
uPVC due to the addition of plasticizers like phthalates such as diisononyl phthalate or DINP. Flexible PVC is commonly used in construction as insulation on electrical wires or in
flooring for homes, hospitals, schools, and other areas where a sterile environment is necessary. Rigid PVC is also used in construction as pipe for plumbing and siding that is commonly
called vinyl in the United States. It is also used for bottles, other non-food packaging, and cards (such as credit or membership cards). It is also used imitation leather, signage,
phonograph records, inflatable products, and many applications where it is used as a replacement for rubber.
Pure polyvinyl chloride is a white, brittle solid generally delivered as powder or pellets. It is insoluble in alcohol but slightly soluble in tetrahydrofuran.
PVC is manufactured from petroleum. The production process also uses sodium chloride. Recycled PVC is broken down into powder or small chips with the impurities removed. The resulting
product is refined to make pure white PVC. It can be recycled approximately seven times. Its lifespan is about 140 years.
31
Thermoplastic
polymers
Thermoplastic polymers are plastics that can be heated to a certain temperature to make them pliable and moldable. When cooled, they solidify into their new shape. Thermoplastics are
recyclable because they can be reheated and reshaped many times.
32
Plasticizers
Plasticizers are substances that make materials softer and more flexible. They are added to polymers to improve their processability and flexibility.
How plasticizers work:
Plasticizers decrease the viscosity of a material
They increase the plasticity of a material
They reduce friction when handling a material during manufacturing
They reduce interactions between segments of polymer chains
33
ethylene
Ethylene is a colorless, flammable gas with a faint sweet odor, chemically represented as C2H4, which is a key component in the petrochemical industry and is widely used in the production
of plastics, primarily polyethylene, as well as playing a crucial role as a plant hormone that triggers fruit ripening in many fruits and vegetables; essentially, it's the most widely
produced organic compound globally.
34
Chlorine derived from salt
chlorine is derived from salt (sodium chloride) through a process called electrolysis, where an electric current is passed through a brine solution (salt dissolved in water) to separate
the sodium and chlorine ions, producing chlorine gas as a result; essentially, salt water chlorination systems used in swimming pools utilize this principle to generate chlorine on-site
