Like tin-based thermal stabilizers, the Thermal Stabilizers BaZn, CaZn, MgAlZn for PVC They are responsible for slowing down the thermal degradation of PVC. The mechanism consists of preventing the formation of hydrochloric acid (HCl) caused by high processing temperatures. There are different levels of protection for this. PVC suspension and emulsion, which serve various industries such as medical, food, toys, footwear, electrical, among others. Some of our degrees are: free of phenols (BPA), heavy metals and phthalates.
These thermal stabilizers for PVC They are the new trend in the market and the future of the market. PVC; These have come to replace others metallic salt stabilizers and lead in electrical cable applications. Among the new developments are grades that comply with California Standard 65, which are free of BPA, phthalates, and other substances.
It has been found to have great potential for use in medical, food and toy applications, not only because of its low odor levels but also because it is considered a completely non-toxic material.
These thermal stabilizers for PVC They arose from the need to remove the Cadmium in PVC to comply with toxicity standards. This product's performance is excellent in terms of thermal stability; however, there are varying degrees depending on its application, as well as the formulator's criteria. PVC. We offer powder grades, but liquids are the most common. Their application is limited to general-purpose markets, such as... plastisol, film, injection-molded parts and flexible profiles. It is recommended for use for Flexible and semi-rigid PVC.
It is important to know that depending on your application we offer grades of low volatile content, plate-out, weather resistance and good initial color.
It is a variant of the other metallic salt stabilizers with the intention of obtaining good thermal stability and reducing the issue of toxicity to the maximum, thus making it possible to use it in medical applications such as blood bags or venoclysis.
Within the thermal stabilizers for PVC made of metallic salts, BaCdZn is being phased out on the market, although there are still some general grades where it is used and where its application poses no health risks. In the local market, it can still be found in... hoses, mats and profiles in industrial sectors. Its advantage is its large thermal stability, Cost-effective, very low plate-out and/or migration, low volatility, and high transparency. It is useful in both Flexible PVC, as well as semi-rigid PVC.
