Rubber Processing
The Marcus homopolymer polyethylenes have
a unique and tailored combination of physical and chemical characteristics,
which coupled with their excellent compatibility features and chemical
inertness, makes them outstanding high performance additives for the processing
of natural and synthetic elastomers.
Their nature provides an extremely effective
lubricant function with minimal detrimental influence upon curing rates
and mechanical properties. Consequently, when incorporated at levels between
2 - 10 % (depending upon the the extent of filler loading), they are highly
efficient in action no matter what the processing method, whether it be
milling, calendering or an internal mixing operation. Equally, there are
benefits to be secured in subsequent extrusion and molding procedures.
For convenience of use the polyethylenes are available in pastille and
powder form, the latter providing ease of dispersion.
A summary of the prime advantages of these
polyethylenes in compounding with natural and synthetic elastomers are:
-
Compatability with elastomers.
-
Good lubricant / release action from
equipment.
-
Excellent flow properties (lower Mooney
viscosity).
-
Easily dispersible.
-
Chemically inert with good electrical
properties.
-
No detrimental influence upon curing
rate.
-
Minimal effect upon mechanical properties.
-
Improved filler dispersion.
