Phenolic resins are mainly used in the production of circuit boards. They are better known however for the production of molded products including pool(Billiard) balls, laboratory countertops, and as coatings and adhesives. In the form of Bakelite, they are the earliest commercial synthetic resin

Chemical properties for the Phenol formaldehyde?

Simple phenolic resins are condensation polymers formed from phenol and formaldehyde. Therefore, they contain only the elements found in phenol and formaldehyde: carbon, hydrogen, and oxygen. The characteristic bond for a cured phenolic resin is a methylene group, derived from a formaldehyde molecule, joining two aromatic rings derived from two phenol molecules. A wide variety of structural formulas are possible, because resins can be made from a variety of ratios between phenol and formaldehyde.


What are the uses of the benzopyrene nucleus?

Benzene today is mainly used as an intermediate to make other chemicals such as styrene, which is used to make polymers and plastics. Benzene is also used to make phenol for resins and adhesives (phenol-formaldehyde resins). Smaller amounts of benzene are used to make some types of rubbers, lubricants, dyes, detergents, drugs, explosives, napalm and pesticides. Benzene is also used in the production of cyclohexane by catalytic hydrogenation. Benzene has reduced uses compared to the past due to its carcinogenic properties.


What is cation exchange resin used for?

Cation-exchange resin has a variety of uses in automotive manufacturing and construction; it contains negatively charged radicals that attracts and isolates cations. It is also called a cation deionization resin or water softening resin.

What are the different uses of paraformaldehyde in details?

Paraformaldehyde is a solid form of formaldehyde. ithas the same uses as formaldehyde. Like Formaldehyde, Paraformaldehyde also reacts with phenol, urea, melamine or resorcinol and produce resins used as binders. Regards Sharad Madhukar Koparkar India


What is formaldehyde resin?

Resin is essentially a glue typically used in commercial processes. For example a resin is used as the adhesive (glue/resin) that holds the saw dust together to make particle board. Formaldehyde resin is any resin that uses formaldehyde in production of the resin. Turns out that formaldehyde resins are cheap and very good and therefore widely used. Unfortunately, the formaldehyde off-gasses forever and is commonly at high enough concentrations to be a health risk. The State of CA has lowered their recommended concentration of formaldehyde to avoid cancer risks to just 7 ppb (parts per billion). This is actually difficult to achieve and 98% of the CA homes tested exceeded this 7 ppb concentration. The typical home was 27 ppb or four times higher than recommended. Unfortunately, homes especially those that are energy efficient have even higher concentrations of formaldehyde. 100 to 200 ppb is not uncommon.

What are the properties of MDF?

Medium Density Fibreboard (MDF) is a wood substitute form which is made from fine wood fibres in a resin which is bonded under heat and pressure. It is manufactured by a dry process at a lower temperature than other fibreboards e.g hardboard. The natural glues and resins contained within the wood are not effective. MDF therefore uses artificial bonding agents / resins. The resin used is usually urea formaldehyde, but some fibreboard including exterior or marine quality board will use stronger glues such as phenol formaldehyde. MDF may be used instead of plywood or chipboard. It is dense, flat, stiff, has no knots and is easily machined. It is made up of fine particles and therefore does not have an easily recognisable surface grain. Can be obtained in natural colour in various thicknesses or self coloured. Requires sealing if likelyhood of moisture ingress.


Two important uses of phenol?

Pharmeceuticals and detergents.


Is polyquaternium-10 a type of formaldehyde?

No. Polyquaternium-10 uses quaternary ammonium as a functional group. This is different from formaldehyde, which has an aldehyde as the functional group.


What are the uses of urea formaldehyde?

Urea-formaldehyde is a non-transparent thermosetting resin or plastic, made from urea and formaldehyde.It used in adhesives, finishes, Medium-density fiberboard (MDF), electrical components and sometimes molded into objects. Urea-formaldehyde is also known as urea-methanal. Because it is formed by chemical reactions with formaldehyde is can be an environmental hazard and there is particular concern regarding indoor air quality. Virtually all modern houses and buildings will have some material made with urea formaldehyde. The problem occurs when the chemical reactions involved in manufacture do not completely use the formaldehyde chemical. This has been a serious problem in the past when production processes were shoddy. It is part of the air quality standards of the US Environmental protection Agency.


What is deifference between GRE pipe and RTR pipe?

RTR Pipe(Reinforced Thermosetting Resin pipe) is a kind of composite thermosetting plastic pipe,combing Resin with Fiberglass Roving.In fact,the RTR pipe have a more approperiate name as GRE(Glass Reinforced Epoxy) Pipe, since that uses Epoxy Resin instead of Polyester.GRE Pipe have much superior properties than common RTR Pipe, especially in properties of high pressure resistant.
