Why Polyurethanes?

Notedome™ polyurethane elastomers are high-performance materials with exceptional versatile properties and are available in a wide range of hardnesses and further can vary from light-weight and flexible to strong and rigid.

They are resistant to oil, fuel and seawater and have excellent electrical insulating properties and function well in harsh conditions, outperforming steels and rubbers and can be moulded to almost any shape.

Processing of the two- or three- polyurethane component chemicals is simple, and they require only low heating, simple mixing by hand or machine, and are fast curing and economic to use.

Abrasion and Tear Resistance

One of the main advantages of polyurethane components is their excellent resistance to wear (impact abrasion and tear resistance). These properties are especially important in applications such as solid tyres, scraper blades, mining screens, pump liners and impellors etc.

Cut Resistance

Polyurethanes have excellent cut resistance make them ideal for application areas such as belt scraper blades, mining screens, swarf skirts, concrete moulds, anvil rollers and fork truck wheels. Notedome offers systems that not only maximise cut resistance but also maximise tear propagation resistance which has an additional benefit of increasing abrasion resistance.

Dynamic / Mechanical Performance

The load bearing properties of polyurethanes are excellent making them ideally suited to high load application areas such as rollers in the steel industry, fork lift truck tyres press tools etc.

Oil and Chemical Resistance

Polyurethanes have excellent resistance to fuel, oils, grease, and many solvents. This makes them especially suited to applications such as automotive (suspension bushes, engine mounts, hoses) steel and aluminium manufacture, coil / can coating and printing.

Resilience

Neuthane prepolymers can formulated to offer a broad range of rebound resilience from almost zero to above 80%. This allows the customer to determine the degree of energy transfer required, especially important in suspension mounts and bump stops, and in the case of wheels (e.g. roller blades) to minimise the rolling resistance.

Natural Resistance

Polyurethanes exhibit very good resistance to ozone and oxygen and general weathering. Resistance to water at ambient temperature is also very good. High temperature, wet or humid applications will degrade conventional urethane but Notedome offer a range of speciality system which maximise the potential of polyurethanes in demanding application areas such as wringer rolls used in the steel industry.

Electrical Properties

In general, polyurethanes are non-conductive, however Neuthane systems can be supplied to meet the requirements of antistatic application areas (e.g. rollers processing plastic films) or to meet the demands of application where true conductivity is required (e.g. certain printing processes, fork truck wheels used in paint / solvent stores).

Electrical components can be encased in polyurethane to protect them from seawater and the general environment.

Flex Resistance

Some application areas impose high demands on elastomers by repeated flexing of thin sections. Polyurethanes can be formulated to offer excellent flex resistance for use in application areas such as moulds in the ceramics industry.

Temperature Range

Polyurethanes can often withstand temperatures between -80°F (-60C°) to +200°F (+90C°).

Flame Retardancy

Notedome offers flame retardant systems and additives to allow their use in application areas such coal mining.
