DOW CORNING MB25501 Masterbatch is a pelletized formulation containing 25% of a functionalized high molecular weight siloxane polymer.
It is designed to be used as additive in resin compatible systems to improve processing and modify surface characteristics.
Silicone-based plastic additives have been used in the plastics industry for several years to improve the mold release and flow of thermoplastics.
They are effective in this role, although until now some difficulties have been experienced in the accurate incorporation of low-viscosity liquids into thermoplastic melts without use of specialized equipment.
The DOW CORNING MB Series Masterbatches address these problems by supplying a high concentration of a high molecular weight siloxane as a dispersion in a dry pellet form in a variety of thermoplastics.
The siloxane is finely dispersed at a fine particle size in the thermoplastic matrix as the discontinuous phase.
The functionalized siloxane has unique advantages over standard polydimethylsiloxane (PDMS).
The functional groups provide an attraction of the siloxane molecule to the metal surface during processing.
This allows for processing aid advantages as well as surface property modification, i.e., lower coefficient of friction. |
