What Is Wood Glue?
It is an adhesive used to tightly bond pieces of wood together. It is white and odorless and has a relatively high viscosity. This adhesive is made of polymer materials and has great flexibility.
This chemical product can be dissolved in water and plastic paint. It is used in various industries, especially in wood and carpentry industries, handi crafts, and furniture making.

History:
A few thousand years ago humans used a type of glue made of animal protein. It is still used today and preferred in some applications.
But from the beginning of the 19th century, wood glue gained a special place in Europe.
Its use reached its peak in the First World War and in the construction of ships, trains, planes, and trucks.
Now animal glue especially hoofs and hide glue, was the primary adhesive of choice for many types of woodworking, including furniture and lutherie, for many centuries.
Types:
There are different types of wood adhesive, each of which has a specific application according to its ingredients and adhesive strength.
The most popular types are:
1- Polyvinyl Acetate (PVA wood Glue):
PVAs are traditional glues and some of the most common adhesives. They are also called “Aliphatic Resins”, “White Glue“, and “School Glue”. PVA belongs to polyvinyl esters and is a type of thermoplastic.
Polyvinyl acetate provides a strong wood-to-wood bond but will not adhere strongly or consistently to nonporous materials, such as metal or plastics. this is the most common wood glue at home depot.
2- Polyurethane Glue:
Polyurethane is one of the best waterproof wood glues available. Polyurethane adhesives are normally prepolymers terminated with isocyanate groups.
In addition to wood, this is used in metals, stones, plastics, and ceramics.
It does not air-dry like PVA glues, but instead chemically reacts with moisture in the objects being glued or even in the air. It expands when it cures, improving adhesion where the fit is not tight.
Polyurethane glue has high adhesion and does not damage wood components and details.
3- Epoxy Glue:
Epoxy, usually as a two-part mix system, cures under a wider range of temperatures and moisture content than other glues.
They are very strong adhesives with high-filling properties. Epoxy wood glue does not require pressing.
They are water-proof and they can be blended with a dry powder with an appropriate color to balance it with the color of the wood.
The use of double-component epoxy requires careful attention to the mixing ratio of the two parts. It bonds to most cured wood adhesives (except PVA).
4- Cyanoacrylate glue:
This glue is usually used for gluing surfaces that are hard and strong, and the drying speed is usually high. Even apart from carpentry, this glue has many uses in homes. Cyanoacrylate, or CA glue, is used to join hard pieces together.
It cures in a very short period of time which is one of its advantages. The adhesive strength of this type of glue is very high and you can only remove it if you break or separate the wooden item.
This adhesive model increases its speed when it is placed in the desired area using an activating spray. It’s one of the strongest wood glue.
5- Hide Glue:
This type of glue is made from animal hide. It is mostly used in making instruments such as bows, guitars, etc. There are two types of hide adhesive. The first is hot hide glue, which is prepared by heating it in a container with water.
When heated, it becomes liquid and when cooled, it becomes solid. This type of adhesive should be applied with a brush in the desired place.
Another type of hide glue is liquid skin glue that offers in a bottle. It can be used just like PVA glue.
The advantage of using liquid hide glue compared to PVA is that: «It is transparent wood glue and does not leave any mark at the place of use».
Most wood adhesives should be clamped while the glue sets. As a result, woodworkers usually use tight joints that require surprisingly little glue to hold large pieces of wood together. Therefore, most of them must be clamped while the glue hardens.

I have a mdf factory. which kind of these glues are the best for mdf on mdf?
PVA epoxy wood glue is good
I did not understand how to use animal wood glue
I think you mean hid glue. When hid glue heated, it becomes liquid and when cooled, it becomes solid. This type of adhesive should be applied with a brush in the desired place.
There are several types of wood glue available in the market. Here are some of the most common ones: 1. PVA glue: PVA (polyvinyl acetate) glue is the most commonly used wood glue. It is water-based, dries clear and is easy to clean up. PVA glue is suitable for most woodworking applications, and it can bond a variety of materials including wood, paper, fabric, and some plastics. 2. Polyurethane glue: Polyurethane glue is a two-part adhesive that creates a strong and durable bond. It reacts with moisture in the air to expand and fill gaps, and it can bond a variety of materials including wood, metal, plastic, and ceramics. 3. Cyanoacrylate glue: Cyanoacrylate glue, also known as super glue or CA glue, is a fast-drying adhesive that works well for small repairs and crafts. It bonds almost instantly and has a strong hold. However, it is not suitable for all materials and can be brittle. 4. Epoxy glue: Epoxy glue is a two-part adhesive that creates a strong and permanent bond. It can be used for a variety of materials including wood, metal, and plastic. It is often used for structural bonding and can fill gaps and holes. 5. Hide glue: Hide glue, also known as animal glue, is made from animal hides and bones. It has been used for centuries and is still used by some woodworkers because of its strength and the fact that it can be reversed with heat and moisture. However, it requires more preparation and can be messy to work with.

Which wood glue is better for furniture?
In general, for making a wooden frame for a sofa, PVA glue can be a reliable choice, especially if the frame is not subjected to excessive stress or moisture. Ensure that the surfaces are clean and properly prepared before applying the glue to maximize its bonding strength. If you anticipate the frame to endure heavy loads or more challenging conditions, using epoxy glue could offer added strength and durability.
Remember to follow the manufacturer’s instructions and consider the specific requirements of your project when selecting and applying the wood glue.
