What type of plastic is sebs?
Poly(Styrene-Ethylene-Butadiene-Styrene) Elastomer
What are polyhydroxy aldehydes?
Hydroxyl groups are -OH molecules that form the 'alcohols' in organic chemistry. 'Poly' equates to 'many.' An important polyhydroxyl group is 1, 2-ethanediol (ethylene glycol) C2H4(OH)2 which is in anitfreeze for cars I think.
What is the outer layer of an escutcheon?
The outer layer of an escutcheon which is the protective sheet is normally made from LDPE (Low density Poly Ethylene). It is used to prevent any aesthetic damage to the escutcheon and will be removed at the customer end.
What is the Name of the small molecule used to make polythene?
Poly(methylene) is the IUPAC name of polyethene. But IUPAC also suggest polyethene to be a correct usage.
What is the plastic used as non-stick coating on cookwares?
PTFE or Poly Tetra Fluoro-ethylene is a Polymer commonly used as insulation but also used to coat non-stick frying pans.
What is the fullform of PEG?
The full form of PEG is "Polyethylene Glycol." It is a polymer compound commonly used in pharmaceuticals, cosmetics, and food products.
What are the derivatives of ethylene oxide?
Products derived from EO have many different uses. They include:Monoethylene Glycol: Production of polyethylene terephthalate (polyester fibers, films and bottles), antifreeze and coolants for engines, heat transfer liquids and aircraft and runway anti-icing and deicing fluid.Diethylene Glycol: Polyurethanes, polyesters, softeners (cork, glue, casein and paper), plasticizers, gas drying and solvents.Triethylene Glycol: Lacquers, solvents, plasticizers, gas drying and humectants (moisture-retaining agents).Poly(ethylene) Glycols: Cosmetics, ointments, pharmaceutical preparations, lubricants (finishing of textiles, ceramics), solvents (paints and drugs) and plasticizers (adhesives and printing inks).Ethylene Glycol Ethers: Brake fluids, detergents, solvents (paints and lacquers) and extractants for SO2, H2S, CO2, and mercaptans from natural gas and refinery gas.Ethanolamine: Chemicals for textile finishing, cosmetics, soaps, detergents and natural gas purification.Ethoxylation products of fatty alcohols, fatty amines, alkyl phenols, cellulose and poly(propylene glycol): Detergents and surfactants (nonionic), biodegradable detergents, emulsifiers and dispersants.
What is the full form of ldpe?
low density poly ethylene
What is Poly Ethylene Terephthalate a thermoplastic or thermo setting?
a thermoplastic
What are the names of petrochemical feedstock products?
Glycol ethers, ethylene, poly ethylene, ethylene oxide, ethanol, propylene, iso propyl alcohal, acrylonitrile, polypropylene, propylene oxide.. these are some examples for petrochemical feed stock products.
What is the full form of PET?
PET means Poly Ethylene Terephthalate.
What is a pegylated treatment?
It is treatment in which a Poly-Ethylene Glycol polymer is attached to another molecule, such as interferon, for the treatment of hepatitis (for instance). The term, pegylated, is derived from the acronym P-E-G, from the chemical, polyethylene glycol. Pegylation can sometimes render a treatment more effective, such as is the case with pegylated interferon treatment (versus standard interferon treatment).
How is plastic made today?
Plastic is poly-ethylene. it is made by the polymerisation of ethylene or ethene and they add some chemicals to strengthen the bonds
What is poly ethylene trephthalate made?
Polyethylene terephthalate (PET) is made through a polymerization process that involves reacting ethylene glycol with terephthalic acid or dimethyl terephthalate. This reaction results in long chains of repeating units, forming the PET polymer, which is commonly used in the production of plastic bottles, clothing fibers, and packaging materials.
What type of plastic is sebs?
Poly(Styrene-Ethylene-Butadiene-Styrene) Elastomer
What can hydrofluoric acid be transported in?
Containers made of paraffin and poly(ethylene) and -(propylene).
What is the monomer of poleyster?
Polyesters are co-polymers, meaning they have more than one monomer. Instead of a chain made of repeated identical units, A-A-A-A-A-A-A-....., they have alternating units, A-B-A-B-A-B-A-B-.....In theory you start with a dicarboxylic acid such as terephthalic acid with a diol such as ethylene glycol, which react by a series of condenstation reactions to form the polymer. In practice they often start with acid derivatives such as dimethyl terephthalate, which then reacts by a transesterification reaction with the glycol. The precise monomers depend on which polyester you are making, but terephthalic acid and ethylene glycol make the commonest one, poly(terephthalic ester) or PET.
