PVC environmental stabilizer is widely used, its security issues are now more and more people's attention. In the study of PVC environmental stabilizer safety should be considered from three aspects, one is the use of raw materials processing of the safety, and second, the user's safety protection, the third is the safety of waste on the environment. The safety protection of the processor can be solved by the liquefaction, paste and granulation of the stabilizer. For the safety protection of the user, the stabilizer can be quantified or the reactive stabilizer is prepared to improve its resistance to desorption, but considering that the stabilizing effect is a molecular chemical reaction, the above method is not the most suitable method, Of the method or the use of high safety stabilizer. In the selection of stabilizers, it is also necessary to consider the safety of the chemicals produced by the reaction between the resin and the stabilizer, or the stabilizer, during the stabilization process.

From the safety of various types of stabilizers, cadmium stabilizers will cease to be used in the near future. But this is a slow process, one of the reasons is that most of the cadmium-free stabilizer in use when the cost to rise 10% -20%, and cadmium-free stabilizer can not be used for a wide range of PVC mixture. If the processing range is narrow, often need to use auxiliary stabilizer to make up for its performance defects. Now the performance of cadmium-free stabilizers has reached the performance of cadmium stabilizers. Calcium and zinc stabilizer has been rapid development. And the powder, paste and liquid, as well as the standard and non-toxic level of sale, the second generation of calcium and zinc stabilizer in food and drug packaging has replaced zinc and tin tin. Lead class stabilizer because of its extraction set is small, so the use of safety is not a problem, but there are environmental hazards. Due to the low cost and high efficiency of lead stabilizers, many companies use this. With the development of non-lead PVC composite stabilizers, lead salts are being replaced by non-toxic environmental stabilizers. Due to the ban on lead in many countries, lead stabilizers are emerging from the market.

In short, pvc environmental stabilizer is moving in a safe, non-toxic direction, the prospects are broad.
