Polypropylene, a compound of the polyolefins family, is the lightest plastic known, highly crystalline and therefore hard, has a high chemical resistance and excellent dielectric properties. Resists temperatures ranging from -10 ° C up to 100 ° C depending on the fluid to be handled. In weather conditions, his resistance is very satisfactory, it does not require paints or coatings. For installations that transport liquids that tend to release sediments, the VALTIC polypropylene CHEDULE 80 is ideal because it does not allow incrustations, it does not pollute and it does not present effects of migration of heavy metals, for this reason the food and pharmaceutical industry uses VALTIC pipelines. The installation is simple; practical and versatile, the fittings can be made in threaded form; welding by socket or butt thermofusion.
