Synthetic resins, also called plastic resins, are those used for the manufacture of plastics, as it is a very economical, lightweight, durable, versatile and easy to maintain material. There are different types of resins with different characteristics. In this article we tell you all about their uses and applications.
Synthetic resins or plastic resins are a material with similar properties to natural resins (a viscous liquid capable of hardening permanently) but very different in chemical structure.
The chemical structure of plastic resins are polymers (macromolecules), made of monomers or chemical compounds of low molecular weight that through a process called polymerization are grouped together forming a new compound: the polymer. These are free of altering composition and body patterns by synthetic resins and fillers, plasticizers, stabilizers, lubricants, the composition of additives such as color material.
POLYCARBONATE vs. RESIN
It is made of oil, gas and air: from crude oil, paraxylene is extracted and oxidized with air to obtain terephthalic acid. Ethylene, obtained from natural gas derivatives, is oxidized with air to form ethylene glycol. The combination of terephthalic acid and ethylene glycol results in PET.
A hydrocarbon that belongs to the polyolefin family and is produced from the polymerization of propylene. Its molecular structure consists of a methyl group (CH3) bonded to a vinyl group (CH2). Polypropylene can also be copolymerized with ethylene to form random copolymers (for transparency and gloss) and impact copolymers (impact and low temperature resistance).
Its composition includes carbon and hydrogen in the form of ethylene, derived from oil or gas, and chlorine. The virgin resin is mixed with specific additives to obtain the required properties: flexibility, transparency, texture or color.
What is the difference between liquid glass polyester resin and PET?
PET plastic is one of the most commonly found plastics in water bottles, juices, beverages and textiles, it is also the plastic that most recyclers and recycling points receive, and one of the easiest to replace, you only need to start using a reusable bottle to begin to stop using PET.
PET was first produced in 1941 to be used as a textile fiber to help make up for the wartime shortage of cotton. In the 1950s it was used in the food industry as an ambassador, and its production became widespread in the 1970s when it began to be used as a rigid container for beverages and carbonated water.
It is generally known for its use in pipes, but it can also be found in oil bottles, shampoo, medicine containers, meat packaging, sausages, tablecloths, to name a few. PVC is considered toxic due to the use of chlorine in its manufacture, and it also emanates vinyl chloride, which can pass into liquids (pipes or water bottles) as the temperature rises.

Monomers are the building blocks of the structure of plastics (e.g. ethylene). They are simple molecules (carbon and hydrogen). The union of many monomers constitutes a polymer (e.g. polyethylene).
It is produced through terephthalic acid and ethylene glycol by polycondensation. There are two types: textile grade and bottle grade; for bottle grade it must be post-condensed, and there are different colors for these uses.
It is a thermoplastic manufactured from ethylene (made from ethane, one of the components of natural gas). It is very versatile and can be transformed in different ways: injection, blow molding, extrusion or rotational molding.
It is produced from natural gas. Like HDPE, it is highly versatile and can be processed in different ways: injection, extrusion, blow molding and rotational molding. Its transparency, flexibility and economy make it present in a variety of containers, alone or in conjunction with other materials and in a variety of applications. Advantages
