Thermoplastic glue (Hot Melt Adhesives / glue sticks) may have been invented around 1940 by Procter & Gamble as a solution to water-based adhesives commonly used in packaging at that time failing in high humid climates, causing packages to fail and pop open.
What is the history of the hot glue gun?
Early hot melt glues were applied using a brush or poured from a pot. This was messy, time-consuming, and often left users with burns and blisters. In 1954, George Schultz was said to have invented his Polygun – the first glue gun. The technology was simplistic, and loading the glue was difficult.
What is the history of glue?
The earliest glues were made from various plant-based materials. The oldest known compound glue was made from plant gum and red ochre approximately 70,000 years BC, and was found in South Africa, so our ancestors were figuring out ways to stick two things together a long, long time ago!
What is in hot melt glue?
3. What are hot glue sticks made out of? Three thermoplastic elastomers are commonly used for making glue sticks: EVA (Ethylene Vinyl Acetate), APAO (Amorphous Poly Alpha Olefin), and PA (Poly Amides). Various tackifiers are also incorporated in these hot melt glue sticks.

What is hot melt? Hot melt or hot glue consists of thermoplastic polymers that when melted, apply as a liquid but become a solid again as they cool. Hot glue is used in both commercial and residential areas. It is used for a variety of things crafts, hobbies, woodworking, assembly, packaging, labeling, etc.

Hot glue sticks are produced by combining polymers with various additives. The selection of polymers, which include materials like ethylene-vinyl acetate (EVA) and polyethylene, among others, determines the glue's properties such as strength, flexibility, and heat resistance.
Why is hot glue called hot glue?
As already mentioned, hot glue is applied in a liquid (molten) state after being heated to the adhesive's application temperature. Ensuring the glue is hot enough guarantees a good “wet out” of the first substrate, with glue able to fill small crevices on its surface.
What was the first glue?
World's oldest glue used from prehistoric times till the days of the Gauls. Birch bark tar, the oldest glue in the world, was in use for at least 50,000 years, from the Palaeolithic Period up until the time of the Gauls. Made by heating birch bark, it served as an adhesive for hafting tools and decorating objects.
What was glue originally made of?
Stone age sites in Italy and Eastern Africa show that early humans used birch tar and red ochre to make glue. Furthermore, artefacts found at both Sibudu Cave and Rose Cottage in South Africa show evidence of the use of “compound adhesives” over 70,000 years ago.
Where was glue made from?
Glue, historically, is indeed made from collagen taken from animal parts, particularly horse hooves and bones. In fact, the word “collagen” comes from the Greek kolla, glue.
What are the interesting facts about hot melt glue?
Hot melt adhesives contain no solvents, and no water. They set by loss of heat. This gives them a very fast setting speed. They can bond two non-porous materials.
How does hot melt glue work?
Hot-melt adhesives are 100% thermoplastic polymer adhesives that are solid at room temperature. When heated above their softening point—a relatively low temperature compared to many packaging components—hot-melt adhesives liquefy, allowing for their application to several packaging and other applications.
What are advantages of hot melt glue?

What is the meaning of hot melt?
Generally, super glue is stronger than hot glue. Super glue is a type of adhesive that sets quickly and forms a strong bond between two surfaces. Hot glue is a type of adhesive that is melted and then applied to two surfaces. It sets more slowly than super glue and does not form as strong of a bond.
What is stronger than hot glue?
Hot glue is suitable for various materials, and it's often used for crafting, household repairs, and other applications where a fast bond is needed. However, hot glue may not be as strong as epoxy in terms of sheer strength and long-term durability.
Is hot glue stronger than epoxy?
Hot glue guns are great for so many projects. The bond formed is very strong and the glue adheres to all kinds of materials. The concept is simple: a glue stick is inserted into the glue gun and then heated until it melts. The melted glue is applied to a surface to bond materials together.
Is hot glue a strong glue?
Hot melt glues liquefy at temperatures ranging from 250 to 375 degrees Fahrenheit. If there is too much moisture or humidity in the air, it can prevent glue from drying and impacting bonding.

Neanderthal tools might look relatively simple, but new research shows that Homo neanderthalensis devised a method of generating a glue derived from birch tar to hold them together about 200,000 years ago—and it was tough. This ancient superglue made bone and stone adhere to wood, was waterproof, and didn't decompose.
What did early humans use for glue?
The first references to adhesives in literature appeared in approximately 2000 BC. The Greeks and Romans made great contributions to the development of adhesives. In Europe, glue was not widely used until the period AD 1500–1700. From then until the 1900s increases in adhesive use and discovery were relatively gradual.

What are some advantages and disadvantages of hot melt glue?
Although hot melt adhesives have occasionally been used as tail tie adhesives they have hitherto been for the most part unsuitable for pick-up and tail tying because they have not been water soluble and hence would leave residues which interfere with repulping of scrap paper.
What is the difference between hot melt and cold melt glue?
Hot melt adhesives can be made of a poly amide, polyester, polyurethane, or even EVA. Melting the adhesive will set of the chemical reactions which helps in forming the cross links within the adhesive. This cross linked product binds the two substrates. Why does ice melt when it gets warm?
Is hot melt glue water soluble?
It is made of thermoplastic polymers combined with wax, tackifiers and mobilizers to give the polymers their adhesive power. This means that hot glue becomes sticky and moldable at high temperatures and re-solidifies when it cools, therefore bonding items together at a very high setting speed.
How is hot melt glue made?
Hot glue (also called “hot-melt adhesive”) is a 100% solid thermoplastic that is applied in a molten state and forms a bond on cooling to a solid state. Most hot melts lose tack as they solidify; those that retain their tack are known as pressure-sensitive adhesives.
What type of glue is hot glue?
Key point 2: Apply a certain pressure: after the hot glue is applied to the items to be bonded, bring the two materials together and apply a certain amount of pressure. Only by applying pressure can the molten hot glue properly penetrate into the tiny gaps of the materials, resulting in a stronger bond.
