Product Properties:
Heat Stability: DX-181 has high efficient heat stability and good early color stability.
Transparency: The products processed with DX-181 have superior transparency, clear color, little gas and no educt.
Process: The excellent high-temperature color stability and long-term dynamic stability provided by DX-181. 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 methyl tin mercaptide compared with butyl tin or octyl tin 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.
Applications
PVC film (thermal shrinking packaging film, printing film, calendared film, twisting film)
PVC sheet (clear flexible and rigid sheet,istmas sheet, advertisement sheet, compound sheet)
PVC granule (granule, shell of electronic communication apparatus, etc.)
PVC building and construction materials (drinking water pipe and pipe fittings, chemical pipes, construction materials, profile etc.)
PVC medical apparatus (transfusion device, etc.), food packaging materials, daily-used appliances and others
