Heat stabilizer is mainly used for PVC and other chlorinated polymers

PVC is mainly used for PVC heat stabilizers and other chlorinated

polymers. PVC has been found only in the plastic molding process to above

160 ℃, while it is in the 120 ~ 130 ℃ thermal decomposition begins,

releasing HCl gas, HCl is generated if it does not inhibit the

decomposition will further exacerbate this problem has been plagued The

main problem of development and application of PVC plastic.
The study found that if the amount of PVC-containing plastics, such as

lead salts, metal soaps, phenols, aromatic amines and other impurities,

which will not affect the processing and application, but also to some

extent, delaying the thermal decomposition effect. The above problem can

be solved, thus contributing to the establishment of research in the field

of heat stabilizers and continue to develop. PVC heat stabilizer is

polyvinyl chloride (PVC) processing essential additives. With concern for

human health and ecological environment growing, countries have

promulgated a series of laws and decrees, and take various measures to

limit the use of heavy metal heat stabilizers containing lead, cadmium and

other. Outside the industry generally believe, PVC heat stabilizers

environmental protection has become the development trend will not be

reversed. In recent years, the process of environmental protection PVC

heat stabilizers, instead of the traditional WSD Plastic impact modifier  lead, cadmium heat

stabilizer, research and development of non-toxic, non-polluting, complex,

and efficient heat stabilizers has been more widely appreciated, its

synthesis and applied research made a lot of  WSD stearic acid new progress.
With the implementation of the people's awareness of environmental

protection regulations and decrees, PVC heat stabilizers to be non-toxic

and environmentally friendly direction of the trend. Our heat stabilizer

industry should conform to this trend and accelerate the pace of

structural adjustment, increase calcium zinc stabilizers, organic

stabilizer environmental products research and WSD Metallic stearate  development efforts,

emphasis on research auxiliary heat stabilizers and heat stabilizers

complex system, and promote China environmental process PVC heat

stabilizers.
