Phenolic resin is a heat-cured plastic formed from the reaction of a carbon-based alcohol and a chemical called an aldehyde. Formaldehyde is a common raw material for this type of resin, but other related chemicals can be used.

How are phenolic resins obtained?

The phenolic resin, with an approximate density of 1.25 kg/dm3, is obtained by polymerization between phenol and formaldehyde; This polymerization can be carried out using phenol analogs such as: cresols or resorcin, among others.

What does the word phenolic mean?

Phenolic compounds or polyphenols constitute a wide group of chemical substances, considered secondary metabolites of plants, with different chemical structures and activity. encompassing more than 8,000 different compounds.

What kind of plastic is phenols?

Phenol is a polymer laminated at very high pressure, which has characteristics that make it very useful. One of them is that its own composition makes it a thermostable product. It is a plastic composed of a cotton canvas base with phenolic resin.

This product is also known as polymethyl methacrylate, PMMA (acronym in English) or Acrylic (in Latin America). It is, in short, a transparent plastic material, one of the lightest and most resistant that you can find. In addition, methacrylate is used both for work on the terrace and indoors.

What kind of plastic is melamine?

Melamine resin, MF resin or melamine-formaldehyde resin (sometimes also shortened to just melamine) is a hard thermosetting material, made by the condensation of melamine and formaldehyde. In its butylated form, it dissolves in n-butanol and xylene.

What is an example phenol?

Phenols are organic compounds that are formed by one or several Hydroxyl Functional Groups (-OH) attached to an aromatic ring (benzene ring). Phenols are a type of Alcohols. They have the following properties: They are slightly soluble in water and highly soluble in ethers and alcohols.

What are the foods rich in phenols?

Foods rich in phenols are onion, tea, red wine, cocoa, virgin olive oil, etc. These substances influence the quality, acceptability and stability of foods, since they act as colorants, antioxidants and provide flavor.

What are phenols and examples?

Simple Phenols: Simple Phenylpropanoids: Having a basic phenylpropanoid backbone (an aromatic ring attached to a 3-carbon chain). Examples: trans-cinnamic acid, p-coumaric acid, and its derivatives such as caffeic acid. Phenylpropanoid lactones (or “cyclic esters”), also called coumarins.

How are resins formed?

Resin, from the Latin resin, is a pasty or solid substance that is obtained naturally from an organic secretion of certain plants. Thanks to their chemical properties, resins are used to make perfumes, adhesives, varnishes and food additives, among other products.

What are Resoles?

Base-catalyzed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of more than one (usually around 1.5). These resins are called resoles. Phenol, formaldehyde, water, and catalyst are mixed in the desired amount, depending on the resin being formed, and heated.

What are the types of methacrylate?

Within methacrylate, we find two types: extrusion methacrylate and casting methacrylate. They may seem like the same product a priori, but they are two different types of methacrylates.

What type of plastic is low-density polyethylene?

Low-density polyethylene is a polymer from the family of olefinic polymers, like polypropylene. It is a thermoplastic polymer made up of repeating units of ethylene. It is designated as LDPE (for its acronym in English, Low Density PolyEthylene) or PEBD (low density polyethylene).

What material is polyethylene?

Polyethylene (PE) is chemically the simplest polymer. It is represented by its repeating unit (CH2-CH2)n. It is one of the most common plastics due to its low price and simplicity in its manufacture, which generates a production of approximately 80 million tons per year worldwide.
