3. Methyltin Mercaptide Heat Stabilizer 57583-35-4 JT-980 Properties

Heat Stability: JT-980 has high efficient heat stability and good early color stability.
Transparency: The products processed with JT-980 have superior transparency, clear color, little gas and no educt.
Process: The excellent hightemperature color stability and longterm dynamic stability provided by JT-980. Without fouling, the time of cleaning equipment is shortened. It is suitable for all kinds of process of flexible and rigid PVC, such as calendaring, extrusion,injection and blow molding, etc.
Amount: On the same condition, less methyltin mercaptide compared with butyltin or octyltin can achieve the same effect.  
Safety: The product of methyltin mercaptide has been approved by American FDA (21 CFR 178.2010) and certified by Germany BGA (IIA, 4C). It can be used in food packaging materials and water pipes etc. It’s safe and reliable.
