- The main performance characteristics:
-
Excellent thermal stability: close to organic tin, especially when used with calcium stearate in a twin-screw extruder.
-
Cost advantage: The price is lower than that of organic tin stabilizers such as methyltin and butyltin, and the dosage is low, with high cost performance.
-
Low toxicity: In the United States, it meets the NSF standard when the dosage is ≤0.4 parts by mass, and is suitable for food contact fields such as drinking water pipes; but it is classified as a toxic substance in Japan. It is widely used in the Chinese market, the Asian market and Africa.
-
Poor transparency: The transparency is lower than that of organic tin and calcium zinc stabilizers, close to lead salts, and it is easy to change color (brown → black) under ultraviolet irradiation.
PVC Antimony Heat Stabilizer:CST-A
PVC Antimony Stabilizer CST-A is Changsheng’s best antimony stabilizer, suitable for the production of PVC packaging films, PVC high-end sheet materials,PVC pipes and fittings,any rigid compounds.
PVC Antimony Stabilizer CST-A is a light yellow viscous liquid, close to the appearance of methyl tin stabilizer, often used to replace methyl tin and calcium zinc stabilizer. But it is not resistant to sunlight.
Antimony Heat Stabilizer For PVC Sheet
PVC Antimony Stabilizer CST-A is mainly used for the production of PVC transparent sheets, and industrial PVC sheets.
Antimony Heat Stabilizer For Pipe and Fitting
Antimony Heat Stabilizer CST-A can be used for the production of non-white PVC pipes and PVC fittings with excellent thermal stability.
Other Changsheng‘s PVC Stabilizers
PVC antimony stabilizer is a kind of heat stabilizer with organic antimony compounds as the core.
Compound optimization is important: adding auxiliary ingredients (such as lubricants, antioxidants) to improve processing performance
PVC Antimony Stabilizer is a new type of stabilizer, it is a very good PVC stabilizer, the only disadvantage is that it is not as resistant to sunlight as methyl tin mercaptide, you can contact our sales team and we will give you a suitable suggestion.
