Silicone Fluids as Internal Processing Aids for Thermoplastics 780357
The addition of a high molecular weight Silicone Fluid to most thermoplastics results in numerous processing advantages and cost savings.
These fluids are mechanically blended with the resin melt to form stable polyblends. Addition to injection molding equipment or extruders can be accomplished either by utilizing a small metering pump or adding the fluid in a pelletized concentrate form similar to color concentrates. Excellent dispersion of the fluid in the resin results when done properly by either method.
The fluid remains in the molded or extruded part in the form of small cells or droplets 2 - 4μ in size. The fluid exhibits no tendency to migrate or bleed. Fabricated parts may be decorated without the need for part cleanup.
