Do we really know what is PVC?

Many times when you hear about molecules, polymers, plastics, etc.., Is thought to be boring or complicated and usually do not have the curiosity to know what the real meaning of the words. Plastic for example, means, capable of being molded. All around us there are several types of plastics, such as: polyethylene, used in grocery bags, polypropylene, which are manufactured with syringes, PET, with bottles being manufactured where we pack drinks carbonated or purified water, among others.

In the case of PVC (Polyvinyl Chloride) home, is a plastic in which more than fifty percent of its membership comes from a renewable source of enormous availability in our seas: salt, making it a sustainable plastic . PVC derived from the polymerization of vinyl chloride monomer, which is formulated to obtain a wide range of common in our daily life.

The vinyl chloride monomer was discovered by Henri Regnault Victor  in1835. It was not until 1930 that Waldo Semon, of the B. F. Goodrich Chemical, found that PVC plasticizer absorbed and processed that transforms into a flexible, since by nature is rigid. So, the PVC emerged as an excellent alternative to new markets and new applications from the decade of the sixties.

But why do we say it is the most versatile plastic? Primarily, is that there is not a plastic that can be processed so as diverse (calandreo, extrusion, injection, rotational molding, dip coating, fluidized bed, thermoforming, among some more), in addition to the variety of finished products you can get with this, ranging from applications in medical products (IV tubing), food packaging (stretch film) Baby items (teethers and toys), construction (electrical cable, rigid pipe, blinds, panels, floor and profiles for windows), automotive (synthetic leather, high temperature electrical wire and flexible profiles), garment (shoes and print shirts, among others) and many applications, both rigid and flexible.

Within the flexible applications, the most important and required additives for formulation are plasticizers. Within the range of commercially available plasticizers, are the phthalic, terephthalic, adipates, benzoates, trimellitates, sebacates and citrates.

In Resymat we have the full range of traditional plasticizers, which include a new generation of bio organic plasticizers, in addition to manufacturing and epoxidized plasticizers polymeric plasticizers. All this stems from a continuous research and consistently developing new technologies, new products and new applications, always seeking PVC not only research, but also from polyurethane with polyester polyols manufacturing, in lacquers, adhesives, and other important markets.
