Trillium produces various specialty dispersants for pigments, fillers and other mineral constituents such as flame retardants. 

Mechanism:  There are two mechanisms by which dispersing aids tend to function.  The first is by molecular bonding of a polar functionality on the dispersant molecule to the polar filler surface (such as by hydrogen bonding).  A non-polar portion of the same molecule is then attracted to the non-polar polymer matrix.  This approach is very effective when a polar mineral filler is compounded into a non-polar polymer such as PP or PE.  The other mechism is wetting by simple surface tension reduction of the polymer.  This allows for effective wetting of a dispersed particle so that mechanical entanglement or weaker molecular attraction forces can take over. This is more effective for more polar polymers such as engineering resins of if organic pigments or fillers are used.

Often times due to the complex interactions of the dispersing aid, other effects are seen in the compound. A good dispersant will not only wet out a pigment or filler faster but also reduce bulk viscosity, maintain or improve physical properties with higher loading levels, reduce torque and pressures, improve color strength efficiency and reduce or eliminate agglomeration or act as a process lubricant. When evaluating a  new dispersant it is important to look for these generally beneficial changes. 

TRILSPERSE  800 is best suited for dispersing pigments and fillers into polyolfins or less polar resins.  The wider the polarity difference the more effective it is.  It works as a coupling agent so physical properties are often improved with its use. Trilsperse 800 is a excellent cost effective carrier wax.  It is FDA approved and can pre-fluxed or simply added at the extruder.

TRILSPERSE 101 is a liquid dispersant that works best for engineering resins where the polymer is more polar. It works by the wetting mechanism discussed above. It can be pre-treated to the surface for the filler or added directly to the resin in the melt phase. 

TRILTREAT 1038 & 1039 are organomodified siloxanes based dispersive waxes.  Primarlity used to pre-treat fillers and flame retardants, they can also be added during compounding.  The TRILTREAT 1000 series will coat the filler and help wet out the polymer onto the surface of the particle. Evidence of coupling has also been observed.  The end effects that can be observed are improved processing due to lower melt flow, faster blending, improved physical properties such as impst resistance, lower blocking, improved slip and smoother surface properties.
