Dow Corning MB50-004 Masterbatch
Additive in polystyrene compatible systems.
DOW CORNING MB50004 Masterbatch is a pelletized formulation containing 50% of an ultrahigh
molecular weight (UHMW) siloxane polymer dispersed in highimpact polystyrene.
It is designed to be used as an additive in polystyrene compatible systems to impart benefits such as processing improvements and modification of surface characteristics.
Liquid siloxane plastic additives have been used for several years to improve the lubricity and flow of thermoplastics.
They are effective in this role although some difficulties have been experienced in the incorporation of liquids into thermoplastic melts without the use of specialized equipment.
It has also been difficult to produce masterbatches with greater than 20% liquid siloxane because of processing difficulty and bleed problems.
The DOW CORNING¢ç MB Series Masterbatches address these problems by supplying a high concentration of an ultra-high molecular weight (UHMW) siloxane as a dispersion in a dry pellet form in a variety of thermoplastics.
Appearance: Off-white pellets
Siloxane content: 50 %
Organic resin: High-impact polystyrene, MI 3.5
Suggested use level: 0.2 to 10 %
