Sanipolymers inhibit a biocompatible solution to make the material and the surface of the object produced more resistant to the attack by microbes and bacteria. The development and proliferation of bacteria on the surface of the object is slowed down and the microbes and bacteria count is strongly reduced, up to 99 percent measured according to ISO22196. The incorporated technology is not cytotoxic and not ecotoxic. It is fully safe in contact with humans and nature. Furthermore the patented technology proves to be suitable for plastics that come in contact with foodstuff or materials for other regulated applications, as it presents no increased migration and it uses only allowed substances.
