Glue and rubber primitive materials are derived from natural animals or plant products or synthetic polymers used in the manufacture of adhesives and rubber. Therefore, to produce a higher quality product, various additives can be used to improve its adhesion properties as well as accelerate the restoration or reduction of their viscosity.
Natural adhesives are easy to use and generally soluble in water. Artificial adhesives are divided into four chemical categories: thermoplastic, thermometer, elastomeric and their compounds. Thermoplastic adhesives, such as polyvinyl alcohol and acrylics, require heat or solvent to bond. Thermal adhesives, which contain epoxies, cannot be heated or destroyed after heating, as they cross-act when bonded. Elastomeric adhesives are based on isoprene rubber or synthetic polymers that have both elasticity and good strength.
Depending on the material we want to bond together, a wide range of adhesives can be used, which can be divided into different categories, depending on their appearance, adhesion, strength and chemical structure. These properties are derived from the Glue and rubber primitive materials.
The most important advantage of using adhesives over other bonding techniques, for example, thermal bonding, mechanical fastening, includes the ability to efficiently distribute stresses during bonding. Other benefits include improved aesthetics and low cost for such a process.
Natural rubber is also obtained from a tree found mostly in Brazil. To make the solid rubber, the tree is hit and the latex is collected in a small cup, where it coagulates in a mass. This mass is collected along with the remaining flow and other parts and processed at high temperature. It destroys most proteins and produces solids. Artificial rubber includes neoprene and latex. Artificial tires are made using a variety of chemical processes.
