MONOTHANE™
Single component elastomers
MONOTHANE™ is used on a world-wide
basis for the manufacture of:
• Printing rollers
• Mechanical handling rollers
• Steel mill rollers
• Anti vibration mountings
• Textile spinners
• Capstan drive units
• Seals
• Gaskets
• Rings
• Isostatic press bags
MONOTHANE is a range of SINGLE
COMPONENT, READY FORMULATED
polyester and polyether based
polyurethane elastomers, available in
the hardness range SHORE A 20 - 95.
• Single Component
• Each hardness grade is ready formulated
- no mixing.
• No Degassing
Low Capital Costs
No mixing or dispensing equipment
is needed. No vacuum degassing
equipment is needed. An efficient aircirculating
oven is required for melt
down at 70°C and curing at 135°C.
A
well sealed mould is also vital. There is
no waste. After melt down the required
amount is tapped off; the drum may
then be resealed for use again. Though
nitrogen flushing is recommended, it is
not essential.
In addition to the standard grades of
MONOTHANE, a range of specially
modified grades (A30P, A40P and A45P)
has been developed specifically for the
manufacture of metal decorating rollers
and can lacquering wheels. Tests have
shown that these grades are suitable for
use with the majority of printing inks
and that subsequently the rollers and
wheels can be easily reground.
MONOTHANE exhibits extreme
durability and performance in demanding applications when compared
with rubbers and other urethane systems.
MONOTHANE™ also overcomes one of the major problems in manufacturing vertically cast rollers, i.e. air entrapment. As the MONOTHANE™ process includes passes through a water-thin stage during the curing process - it automatically de-gasses, producing bubble-free mouldings. This is particularly important when making long rollers of small overall diameter.
Ease of Handling
MONOTHANE may be melted down
in the container at 70°C, poured into a
well-sealed pre-heated metal mould and
then cured at 135°C.
Simply HEAT – POUR – CURE.
