Trillium provides both organic and silicone treatment chemistries for fillers and flame retardants.
Slurry Application: Slurries of calcium carbonate, talc or other fillers can be efficently treated with emulsified organo-modified siloxnes (OMS). These are mixed directly into the slurry with treatment occuring during the drying process. OMS will impart compatability between the resin and the filler. In some cases it will act as a coupling agent as well. In most cases the benefits seen will be improved dispersion, improved speed of dispersion, color strength, improved melt flow, imprved impact strength and other physical properties. and easier processing. The later occurs due to the additional effect of OMS as an exterior process lubricant.
Dry Fluxing: Many treatments can be dry fluxed onto the filler surface in conventional, heated, high-intensity mixer such as a Henschel or Papenmier. The strategy is to blend the filler and treatment (powdered) with high speed while heating a five to ten degrees past the melt point of the treatment agent. The mixing vessle and contents should then be coooled below the melt point of the treatment agent while mixing. The material can be handled without much risk of massing. Failure to mix during the cool down can result in clumping and massing.
Liquid Treatments: Many methods are utilized in treating filler surfaces with liquid treatment agents. These usually take the form of slow addition or injection of liquid into a high-speed mixing vessel during blending.
Typical treatment rates rarely go above 2% by weight of treatment agent to filler. However, some systems do go above this. The excess treatment can perform other functions in the compound or blend such as wetting or lubrication.. The filler surface area dictates how much treatment agent will be used u on the filler surface.
