How many types of plastic resins are there?
At the present time there are marketed around 30 families of plastics with their corresponding formulas. Among those most used we can find the Polyvinylidene Chloride (PVC), High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene (PP) and the Polystyrene (PS), among others.

Where does plastic come from?
The most important ingredient of plastics is petroleum. Naphtha is distilled and starting from this fraction the matters prevails is obtained. It is important to know that 4% of the world production of petroleum is only dedicated to manufacture plastics, 6% goes to other industries and 90 remaining% is used to fuel for heating and locomotion.

Can plastic be combined with metallic materials?
Plastic materials are innocuous and completely adaptive to metallic constructions.

How are plastics made?
The production of plastics is a process called polymerization: chemical reaction with small molecules called monomers combine to each other to form other much bigger molecules to form chains which are called polymers, in those it repeats the structure of the original ones. The monomer is the matters prevails that are manufactured starting from the petroleum. They are presented in diverse forms but, usually, in way of granules -screening -, powder, pastures, among others.

How are objects made of plastic manufactured?
Once produced, plastic polymers can be transformed into different products for the use in various applications .That transformation is carried out through processes like extrusion, injection or compression molding which takes advantage of the "plasticity of resin". Plastic resins are molded by using high temperature, pressure and molds to make the final products. These final products can be used in a variety of applications for domestic, medical and industrial use to name a few.
