South African polyurethane systems specialist National Urethane Industries (NUI) provides advanced polyurethane products and technical solutions for the mining, construction, manufacturing and industrial sectors.

Established in 1982, the company specialises in the formulation and manufacture of coatings, adhesives, sealants and elastomers, offering customers customised solutions designed to address specific operational challenges. NUI asserts that its combination of local manufacturing capabilities and advanced polyurethane technology has led it to develop products suited specifically to African operating conditions.

A key offering in the company’s portfolio is Poly-NUI-Matic Tyre Fill, a two-component polyurethane tyre-fill system engineered for heavy-duty, slow-moving equipment. Developed specifically for tyre-filling applications, the product is designed to eliminate common tyre-related problems in harsh industrial environments.

Developed by NUI, the system is designed to deliver puncture-proof performance to help reduce equipment downtime caused by tyre failures. It also adds ballast weight to tyres, improving stability and machine performance while maintaining a ride quality similar to that of conventional pneumatic tyres. Additional benefits include increased tyre lifespan, the elimination of split rims for improved safety, and reduced maintenance costs, helping operators save both time and money.

Poly-NUI-Matic 73TF18 TYREFILL is used across a range of demanding applications, including underground mining, quarries, forestry operations, earthmoving equipment, freight docks, airports, factory transport systems, and municipal waste and sanitation fleets. Its stated durability and reliability make it particularly suited to environments where equipment uptime is critical to productivity.

NUI emphasises its strong focus on technical support and product development. The company offers tailor-made polyurethane formulations, application expertise and specialist technical assistance. Its research and development team works closely with customers to create custom solutions for demanding applications, ensuring products are aligned with specific industry requirements.

Now part of the Rigifoam Group, NUI explains that it has expanded its reach through national and international distribution channels while maintaining its commitment to locally manufactured products.

NUI invites participants to visit its stand at the upcoming Electra Mining Africa expo to discuss its growing portfolio of engineered polyurethane solutions.
