In accordance the present invention is particularly advantageous to stabilize rigid PVC formulations, designed for use on pipes, profile configuration and plates in the form of transparent and opaque coatings. For transparent coatings, it is preferable to use compounds of the form (I), (II), (III) or (IVb), which have a melting temperature below 190°C. Stabilization is also useful for semi-rigid and flexible formulations and plastisols. This stabilization does not require the use of heavy metals (Sn stabilizers, Pb stabilizers, Cd Zn stabilizers and stabilizers) and can be used for the production of physiologically applicable consumer products made of PVC, including health-care products.

The stabilizing system can be applied in the following ways: in the form of an emulsion or dispersion; as a dry mixture during the mixing of the added components or polymer mixtures; direct addition to the processing device (for example, calender, mixer, kneader, extruder and the like), in the form of a solution, or melt, or, respectively, in the form of flakes or pellets, are part of the same dust-free packaging.

Stabilized PVC of the present invention can be obtained in a known manner using known equipment, for example the above-mentioned manufacturing device for mixing a stabilizing system and, if desired, other additives with PVC Stabilizers may be added individually or in a mixture, and also in the form of what is called the "concentrate".

PVC stabilized in accordance with the present invention, can be produced in a desired shape by using a known method. Examples of processes of this type can serve as grinding, calendering, extrusion, injection molding and centrifugation, and extrusion blow molding.

Stabilized PVC can also be subjected to processing with the formation of foam. PVC stabilized in accordance with the present invention, particularly suitable for the manufacture of hollow articles (bottles), packaging films (film hot stamping), exaggerated films, pipes, heavy specialized products (window frames), transparent wall structures, structural profiles, sidings, fittings, office of protective coatings and buildings equipment (computers, household appliances). Preferably the casting of solid PVC foam and PVC pipe, for example, for drinking water and wastewater pipes to work under pressure, gas pipes, pipes for laying cables and pipes for cable protection pipes for industrial piping, gutters, sewers, gutters and drain pipes.

PVC stabilized in accordance with the present invention can also be used to obtain semi-solid and flexible formulations, mainly because of the flexible formulations for wire reinforced, cable insulation, manufacturing flooring, Wallpaper, vehicle components, flexible films, injection castings or hose, which is particularly preferred. PVC invention in the form of semi-solid formulations particularly suitable for the manufacture of decorative films, foams, agricultural films, hoses, sealing profiles and office films.
