Low density hot melt glue is better in some applications because it offers better flowability and penetration into tight spaces. It also has a quicker set time and can be more cost-effective due to covering a larger surface area. However, high density glue might provide stronger adhesion and be more resistant to heat and humidity in certain applications.

How glue gun heating element works?

A glue gun heating element consists of a metal rod wrapped with a high-resistance wire, such as nichrome. When electricity passes through the wire, it generates heat due to electrical resistance. This heat is transferred to the metal rod, which then heats up the glue stick in the gun to melt it for application.


How does styrophone melts because of glue?

Styrofoam is made of polystyrene, which is a type of plastic that can be dissolved by certain chemicals found in glue. When glue comes into contact with styrofoam, it breaks down the polystyrene molecules, causing the material to melt or soften. The glue essentially eats away at the styrofoam, causing it to lose its shape and structure.


How can temperature affect the strength or adherence of glue?

If heat is exposed to glue than it will melt instead of harden i guessANS 2 -If heat is given to some adhesives, epoxies in particular, they will set faster and become stronger.-It's very important to remember the term 'glue' refers to at least a hundred different formulas. -Simply calling it 'glue' IS NOT GOOD ENOUGH ! - It's all different.


What type of light might cause glass to melt?

Intense heat from sources like a blowtorch or a high-powered laser can cause glass to melt.


Why was the hot glue gun invented?

Hot glue has been used for many centuries, the first hot glue was made by finely grating animal hooves together with a mineral spirit and heated in a double boiler, when soft it was used to glue wood and other porous materials. the glue gun was a natural evolution from the double boiler, it has made the use of hot glue very easy and quick. by the way, they make use of synthetic glue and no longer use animal hooves.
