Hydrogen peroxide (H2O2)
Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond) and an oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution it appears colorless. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species.
Now a days engineering plastics (Polyacetal, polyamide, polycarbonate, polyphenylene oxide, polybutyl terephthalate , and polyethylene terephthalate) are very popular rather then thermoplastic resins.Polyacetal(Acetal Resins or Polyoxymethylene/POM) are any of several polymers of formaldehyde and trioxane.As the molecule has no side chains, dense crystals are foamed, Acetal resins are hard,rigid,strong,tough,and resilient.
TMP is mainly consumed as a precursor to alkyd resins. Otherwise, acrylated and alkoxylated TMP's are used as multifunctional monomers to produce various coatings, Ethoxylated and propoxylated TMP, derived condensation of from TMP and the epoxides, are used for production of flexible polyurethanes.
NPG (Neopentyl Glycol)
NPG is a diol which features unique chemical structure. It has 1,3-position two hydroxyl groups on the primary carbon atom for rapid esterification reaction and two methyl groups, instead of the usual hydrogen atoms, on the alpha-carbon atom for the high chemical and thermal stability. It is a white crystalline solid partially soluble in water soluble in oxygenated solvents and completely soluble in alcohol.
Para-formaldehyde is a polymer of formaldehyde in solid form. containing a percentage of water, readily soluble in order to obtain an aqueous solution or to be used as a reactant by dissolving it in the reaction medium. In chemical terms, para-formaldehyde is a polymer which is obtain by poly-condensation of formaldehyde in aqueous solution. it is formed by a mixture of polyoxymethylene glycols.
White, crystalline powder, readily esterified by common organic acids.
MIBK (METHYL ISOBUTYL KETONE)
MIBK is a good polar solvent with a modern evaporation rate.a single step process is applied for the production of MIBK,which is led to make lower investment cost and operating costs,and avoids the low conversion of acetone.
PA (Phthalic Anhydride)
PA is widely used as phthalate plasticizer,unsaturated polyester resin,dye intermediate.PA manufacturing method is divided into two processes, ortho-xylene process with the specific catalyst,and catalytic oxidation of naphthalene process by fixed or fluidized bed type. P & ID LTD.can provide with ortho-oxylene based process.
MA (Maleic Anhydride)
Maleic anhydride is mainly used for unsaturated polyester resin for housing units and automobiles,fumaric acid for food and succinic acid.
Ethanolamines are a class of organic (nitrogen) compounds with amine functionality at one end alcohol group at the other. they are typically classified as Mono-ethanolamine(MEA), di-ethanolamine(DEA), and triethanolamine(TEA).
Phenol & Acetone
Phenol is white crystalline, odorous and toxic chemical compound .
BPA (Bisphenol A)
Bisphenol A, commonly abbreviated as BPA Known to be estrogenic since the mid 1930s.
Terephthalic acid is poorly soluble in water and alcohols, consequently up until around 1970 most crude terephthalic acid was converted to the dimethyl ester for purification. It sublimes when heated.
