Engineered polyurethane solutions that keep South African mining moving.

In mining, every hour of downtime costs money.
Equipment operates in some of the harshest conditions imaginable. Constant abrasion. Heavy impact. Corrosive chemicals. Extreme temperatures. Components need to withstand continuous punishment while maintaining performance.

That is where National Urethane Industries (NUI) comes in.

For decades, NUI has been engineering high-performance polyurethane systems that help South African industry improve reliability, extend equipment life and reduce maintenance costs.
Whether the application requires exceptional wear resistance, superior adhesion, precision cast components or high-performance sealing systems, NUI develops solutions designed for demanding industrial environments.

One technology. Four specialist solution categories. (C.A.S.E.)

1.       Castings

Polyurethane castings deliver exceptional wear resistance and durability for components exposed to abrasive conditions.   Applications include rollers, wheels, liners, wear parts, screens, bushes and custom-moulded components used throughout mining and mineral processing operations.

2.       Adhesives

Industrial polyurethane adhesives provide high-strength bonding for demanding applications where long-term durability is essential.   Designed for performance in challenging operating conditions, they deliver reliable bonds across a wide range of industrial materials.

3.       Sealants

Mining operations depend on effective sealing systems to protect equipment and infrastructure from dust, moisture, vibration and chemical exposure.     NUI's polyurethane sealants are engineered to maintain performance where conventional products often fail.

4.       Elastomers

Polyurethane elastomers combine flexibility with exceptional toughness.
Their resistance to impact, abrasion and wear makes them ideal for components that must absorb heavy loads while maintaining dimensional stability and long service life.

Supporting South African industry

NUI supplies engineered polyurethane solutions to industries including:
