Will the amount of organotin heat stabilizer used for PVC-U pipes be too much to cause mouth mold precipitates?
Organotin stabilizer is one of the heat stabilizers. The main features are high efficiency, high transparency, excellent heat resistance, and resistance to sulfur pollution.
Organotin stabilizer
It is an additive for plastics.
Mainly used in food packaging film and other transparent PVC products.
Laurates, maleates and mercaptans are commonly used in industry.
Polyvinyl chloride (PVC) processing and molding process, efficient, excellent heat stabilizer, its thermal stability, transparency, are better than other PVC heat stabilizers. Methylmercaptan and its products have been recognized as non-toxic and safe by the West German Federal Health Agency (BGA), the U.S. Food and Drug Administration (FDA) and other world health supervision agencies.
<Product performancent color="#0000FF">Product performance.
It has outstanding performance of inhibiting the pre-coloring of PVC products during processing, excellent UV resistance and long-term stability, good fluidity, good color retention during processing, and good transparency of products. Especially, its light and heat stability reaches the international leading level, and can effectively maintain the secondary processing and recycling.
The tube generally cannot add a lot of stabilizer, the mouth mold precipitation is mostly the lack of lubricant, or the use of low-grade wax caused by.
You can try to add a little A-C 6A.
Follow up question
It should not be caused by the lack of lubrication, the previous lubrication is very little, the mouth mold also has precipitation, now the lubrication increased to three times the original, the mouth mold still exists precipitation
