Why Polyurethanes?

Polyurethane elastomers can be formulated to produce a diverse range of systems which, when cured offer a wide range of hardness, mechanical properties, chemical and environmental resistance. This diversity of design combined with flexible, low cost production methods give polyurethane elastomers a unique position in the market place.

Properties offered by Neuthane polyurethanes are as follows:

Hardness

Neuthane prepolymers and systems are available from 30 Shore A to above 85 Shore D

Abrasion Resistance

One of the main advantages of polyurethane components is their excellent resistance to wear (both sliding and impact abrasion). This property is 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 system 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 is excellent making them an 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.

Environmental 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).

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 Resistance

Polyurethanes can be chosen to operate at temperatures from below 30⁰C to more than 120⁰ C.

Flame Retardancy

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

Innovative Solutions

 Notedome thrive on a customer focused approach which underpins the success of the company. Continual research and development generates new systems on a frequent basis where customers find new applications for polyurethanes or where current systems must be modified to match certain processing or performance criteria. This is a key characteristic of Notedomes customer focused approach.

 Expanding our range of Neuthane systems is made possible by a flexible manufacturing process that allows small to large-scale production with ease making Notedome the perfect development partner for new applications.
