CHEMICALLY MODIFIED POLYOLEFINES
For the first
time in India a range of maleated polymeric resins in granular form
are being manufactured by PLUSS®, entirely based on indigenously
developed technology. These have been found invaluable as additives
in compounding and processing applications.
OPTIM® Polymeric Resins are based on polyolefines and copolymers,
like LDPE, LLDPE, ULDPE, HDPE, PP, EVA and EPDM. These base polymers
are grafted predominantly with maleic anhydride and other functional
groups that impart a degree of polarity to the otherwise nonpolar base
polymers. The additional chemical groups provide exceptional compatibility,
reactivity and adhesion properties to these resins and cause good affinity
towards other polar materials used in blending, compounding, co-extrusion,
printing, and lamination.
Higher filler loadings also become possible.
In such cases OPTIM® replaces the conventionally used low molecular
weight additives like waxes, which have a tendency to plateout and form
undesirable die deposits during processing.
In extruded products, OPTIM® provide
smoother surface finish. In injection moulded products, the better pigment
dispersion and higher flow of the filled compound so achieved make it
possible to mould dimensionally stable thin wall parts or parts with
a profile of varying thickness.
OPTIM® modified polymers are based on PEs, PPs, EVA, and EPDM. They
act by improving interfacial adhesion between the filler and polymer matrix.
Thus, the polar functional groups in OPTIM®, bind with the surface
of fillers like calcium carbonate, talc, mica and glass fibres, while
the polymer backbone of OPTIM® mixes well with the matrix polymer.
This results in a better dispersion of the filler and enhances the mechanical
properties of the compound. Maleated Polymers are known to be excellent
impact modifiers for filled PP and Nylon compositions.
