Polyurethane Block

Durable. Versatile. Customizable.

At Zhengyuanpu, we specialize in manufacturing high-performance polyurethane blocks designed to meet the diverse needs of industries ranging from mining and material handling to automotive and engineering prototyping. Our PU blocks offer an ideal solution for custom machining, prototyping, vibration absorption, and wear protection.

🔶 Product Overview

Polyurethane blocks are solid, rectangular slabs or cubes made from precision-cast or molded polyurethane elastomer. They are widely used as raw materials for further processing, or directly applied as buffers, spacers, vibration isolators, or in tooling and mold making.

Our polyurethane blocks are available in a wide range of Shore hardness levels (from 45 Shore A to 60 Shore D), and custom colors, offering maximum flexibility in performance and design.
