Product Introduction
I. Product Introduction
The A-3500/B-3500 is a solid polyurethane tire compound. The low-hardness polyurethane elastomer produced from it has excellent flexibility and high elasticity. Tires made with this compound not only offer puncture and cut resistance but also possess high strength and high rebound properties, allowing them to withstand heavy loads at certain speeds.
