pvc heat stabilizer significance

With many countries in the world for environmental awareness and increasingly severe environmental problems , related health problems in people's daily lives by everyone concerned . PVC products used as an extremely wide range of general plastic surface , in the heat stabilizer for shoes  traditional PVC heat stabilizers , containing heavy metals such as lead salt heat stabilizer has a good cost advantage , is widely used . However, with the deepening of understanding and found that in the manufacturing process have serious dust pollution, once absorbed by the body after can not be excreted , seriously affecting the health of production workers ; while PVC products containing lead salts in the course will be varies with time precipitation , which also affects the user 's health, especially in  titanium dioxide medicine and health, children's toys and food packaging-related products is particularly serious. Therefore, the traditional heavy metal toxic heat stabilizers will be fully replaced . Future PVC heat stabilizers are mainly concentrated in the direction of non-toxic calcium / zinc composite heat stabilizer and organic tin in two ways. Ca / Zn compound stabilizer due to excellent overall performance and cost-effectiveness will ultimately shape the future country PVC stabilizer system of the subject. It is also about to become the next phase of PVC heat stabilizers hotspot.
In summary , pvc heat stabilizer study glyceryl monostearate  related subjects in previous studies , based on the liquid calcium / zinc composite heat stabilizer metal soap synthesis and complex research to improve synthesis process , improve heat stabilizer comprehensive performance to meet the future needs of multi-functional stabilizer for the relevant enterprises and research institutions to provide a reference . And soft , transparent PVC heat stabilizer complex study to improve thermal stability . If these problems are resolved , there will be our country's non-toxic environmentally friendly PVC heat stabilizers to a higher level , widening environmentally friendly composite heat stabilizer market and shorten the gap with foreign countries . For widening liquid calcium / zinc composite heat stabilizer field of use has a positive meaning , and will directly promote the upgrading and development of the PVC industry .
