If you carefully observe the production materials of many daily necessities and decorations, you will find that there are phenolic resins in many supplies. So, what is a phenolic resin? What is it used for?

Below, Tuba Rabbit will give you a brief introduction to phenolic resin, as well as its uses, advantages and applications, to help you understand this material.

Phenolic resin

Phenolic resin is a synthetic plastic, usually colorless or yellow-brown, in liquid state and solid. Since it is often used in some electrical equipment, it can also be called "bakelite". In terms of classification, phenolic resin can usually be divided into two different resins, thermoplastic and thermoset, but its storage method should be noteworthy, under normal circumstances, it is suitable to be placed in a cool, dry and ventilated place, not in an overheated environment, in addition, it is best to be equipped with fire-fighting equipment.

Advantages of phenolic resins:

The advantages of phenolic resin are that it has good resistance to high temperature and water, and is not easy to burn, and it has good acid resistance, but it has poor alkali resistance. At the same time, phenolic resins are easy to cut and are often used in electrical equipment, so they have good mechanical and electrical properties. In addition, phenolic resin is not easy to degrade and has a long storage time.

Among them, if you dislike the poor alkali resistance of phenolic resin, you can add some components to the phenolic resin to improve, so that the phenolic resin can obtain some special properties, such as alkali resistance, wear resistance and so on.

Uses of phenolic resins

Due to the high temperature resistance of phenolic resin, it can keep the structure of the object unchanged in a high-temperature environment, that is, stability, therefore, phenolic resin can be used in some high-temperature fields, such as some fireproof board and other refractory materials, as well as some casting, thermal insulation materials and so on. In addition, phenolic resin has good water resistance, so it can be made into a binder for bonding wood and other materials.

In addition, phenolic resin is easy to cut, has excellent mechanical properties and good acid resistance, and can be improved by adding some ingredients, which makes it possible to make various compression molding powders, plastics, and some insulating or corrosion-resistant coatings. Due to the non-degradability and good stability of phenolic resin, phenolic resin can be made into a variety of daily necessities or decorative products, which are widely used in people's lives.

The above is the phenolic resin introduced in this article, as well as its advantages and specific uses, I believe that people should have an understanding of phenolic resin, especially its use, after reading this article. If you want to know more about Da Yanguo, it is recommended that you find some products made of phenolic resin, and then understand and study the instructions of these products, especially the raw materials.

The composition and use of phenolic resin are as follows:

Composition: Phenol and formaldehyde are formed by polycondensation reaction under the action of acidic or alkaline catalysts, linear thermoplastic resin is generated when phenol is excessive, and bulk thermosetting resin is generated when formaldehyde is excessive under the action of alkaline catalyst.

The application areas are as follows:

1. Compression powder: The compression powder for the production of molded products is one of the main uses of phenolic resin.

2. Phenolic glue: thermosetting phenolic resin is also an important raw material for adhesives.

3. Phenolic fiber: mainly using thermoplastic linear Nianye phenolic resin as raw material, soaked in the aqueous solution of polyoxymethylene and hydrochloric acid after melt spinning, to obtain formaldehyde cross-linked body structure fiber.

4. Anti-corrosion materials: phenolic resin coatings, phenolic resin FRP, phenolic epoxy resin composite FRP, phenolic resin cement mortar, phenolic resin impregnation, profiled graphite products.

5. Thermal insulation materials: phenolic foam products are characterized by thermal insulation, heat insulation, fire prevention, light weight, as a new material for thermal insulation, energy saving, and fire prevention, it can be widely used in the field of air conditioning systems, lightweight thermal insulation color steel plates, housing thermal insulation, energy reduction, thermal insulation materials for chemical pipelines, vehicles and ships, etc.

The demand for phenolic resin on the market is very large, and many products that we come into contact with in our daily life are made of phenolic resin, such as: switch plugs, sockets, etc. So, today I will talk to you in detail about what isPhenolic resin

What are the uses of phenolic resins?

What is phenolic resin

Many people refer to phenolic resins as bakelite or bakelite powder. Most of the bumper bends on the market are colorless or yellow-brown smiling transparent materials, but now you can also see some red, green, brown, blue, yellow, black and other colors according to continuous creation. Phenolic resins are in powder form, granular form, etc., and will decompose when weak alkali and weak acid resistance will occur when encountering strong acid, and corrosion will occur when encountering strong alkali.

This substance is insoluble in water, but it dissolves easily in liquids such as acetone or alcohol.

Uses of phenolic resins

1. Phenolic glue: solid phenolic resin is also one of the important raw materials of phenolic glue. If it is a single phenolic resin glue, the texture is relatively brittle, and it is mainly used for the bonding of building materials and plywood and precision casting sand molds.

In addition, it is used as an adhesive based on phenolic resin modified by other polymers, so it occupies a very important position in structural adhesives.

2. Phenolic fiber: mainly based on thermoplastic linear phenolic resin as the basic raw material, through melt spinning and then soaked in hydrochloric acid and polyoxymethylene aqueous solution, so as to play a role in solidification, better obtain formaldehyde cross-linked body structure fiber products.

3. Anti-corrosion materials: there are also thermosetting phenolic resin components in the field of anti-corrosion, and the common forms are: phenolic resin fiberglass, phenolic resin coating, phenolic resin cement, phenolic-epoxy resin composite fiberglass, mortar, phenolic resin impregnated and profiled graphite products.

4. Thermal insulation materials: mainly phenolic resin foaming materials, and phenolic foam products are characterized by thermal insulation, fire prevention, light weight, heat insulation, as a new material for thermal insulation, energy saving and fire prevention. It can be widely used in the field of air conditioning systems, lightweight thermal insulation color steel plates, thermal insulation materials for chemical pipelines, housing thermal insulation and energy reduction, vehicles and ships.

5. Compression molding powder: Compression molding powder is one of the main uses for the production of phenolic resin, and compression powder can be made into various plastic products by transfer molding, molding and injection molding. Most of the thermoplastic phenolic resin compression powder is used to manufacture electrical parts such as sockets, plugs, switches, and some daily necessities in life, as well as some industrial manufacturing products.

My conclusion: Above, aboutPhenolic resinIts use performance is extensive, the market demand is large, interested friends can learn about it in many aspects!

Summary. The most important feature of phenolic resins is their high temperature resistance, which maintains their structural integrity and dimensional stability even at very high temperatures.
