Building stronger, sustainable non-pneumatic tires with TPC

Pneumatic tires aren’t ideal for the rugged demands of off-road vehicles and machinery. Their air-filled design makes them vulnerable to punctures, leading to costly downtime, frequent repairs, and reduced productivity. On wet, uneven, or sloped terrain, these tires may also lose traction, causing slippage that can damage work areas or delay projects.

While alternatives like solid rubber or foam-filled tires exist, they often bring their own trade-offs—such as increased weight, less efficient manufacturing, and poor damping or ride quality.

A growing shift to non-pneumatic tire solutions

To meet evolving performance needs, many manufacturers are now exploring non-pneumatic tire technology. Unlike traditional designs, NPTs offer structural support without the need for pressurized air. For sectors like construction and agriculture—where heavy equipment operates in extreme weather and terrain—this shift offers clear advantages.

For these applications, tires must:

• Support heavy mechanical loads
• Operate across wide temperature ranges
• Maintain high durability and flexibility
• Provide traction on slick or sloped surfaces

Envalior's advanced TPEs help make that possible.

Enhancing non-pneumatic tires with Arnitel®

Envalior’s Arnitel® is a high-performance thermoplastic elastomer engineered to meet these exact challenges. With its unique balance of flexibility, strength, and temperature resistance, Arnitel® enables the design of lighter, more durable non-pneumatic tires.

Our collaborative development approach led to an innovative tire concept that integrates an Arnitel® web structure between the metal wheel and the rubber tread. This design not only improves mechanical performance, but also makes the tire more sustainable and cost-effective over its lifecycle.

Arnitel’s block copolymer structure gives it excellent fatigue resistance, high impact strength, and superior load-bearing capacity. These properties help extend tire life—lasting up to three times longer than conventional pneumatic options.

The material also enables excellent adhesion with rubber components. This compatibility allows for better bonding between the Arnitel® web and the outer tread, reducing wear and boosting long-term durability.

Proven resistance to extreme conditions

Arnitel® is designed to perform across a wide range of temperatures—from -30°C to 100°C. it’s exhibiting consistent mechanical properties fluctuate, while ductility is maintained down to -40°C. This makes it a dependable option in both cold winters and hot, demanding work environments.

In addition, the material resists:

• Harsh weather and UV exposure
• Hydrolysis and microbial growth
• Oils and Grease resistance as well as to other Agricultural and industrial chemicals

For manufacturers focused on sustainability, Arnitel® Eco offers a bio-based solution made with up to 75% renewable resources. It delivers the same high performance with a reduced carbon footprint—helping companies meet their environmental goals without sacrificing product strength or longevity.

Non-pneumatic tires built with Arnitel® represent a forward-thinking solution for industries where reliability and efficiency are non-negotiable. Whether you’re engineering equipment for construction sites or agricultural fields, Envalior’s materials can help you build smarter, more sustainable products.
