Polyurethane Dunnage

Polyurethane Dunnage Solutions for Industrial Product Protection

Protecting high-value components during handling and transport is not optional—it’s essential. At Yantai Zhengyuan Polyurethane Co., Ltd., we offer custom-engineered polyurethane dunnage solutions designed to deliver precise protection, impact resistance, and long service life in demanding industrial environments.

🔧 What Is Polyurethane Dunnage?

Polyurethane dunnage refers to molded or machined support blocks, inserts, trays, or cushioning systems made from polyurethane elastomers. These components are used to:

Secure and separate parts during transportation or storage

Prevent scratches, vibrations, and surface damage

Enable repeatable positioning in robotic or automated systems

Compared to rubber, foam, or thermoplastics, polyurethane offers superior dimensional stability, load-bearing capacity, and abrasion resistance.

🏭 Why Choose Polyurethane for Dunnage Applications?

✅ 1. High Durability

Our durable dunnage blocks maintain their shape and performance under repeated loading and unloading. Polyurethane resists compression set and retains its resilience even in continuous-use cycles.

✅ 2. Superior Surface Protection

The elastomeric properties of polyurethane provide a soft yet tough interface, reducing the risk of marring metal, glass, painted surfaces, or composite parts.

✅ 3. Excellent Chemical Resistance

Polyurethane is inherently resistant to oils, greases, and industrial fluids, making it ideal for harsh factory conditions or cleanroom applications alike.

✅ 4. Molded Precision

We offer precision molded dunnage customized to your component geometry, ensuring accurate fit, repeatability, and optimized logistics handling.

✅ 5. Reusability & Cost Efficiency

Unlike disposable materials, reusable polyurethane dunnage inserts are built for thousands of cycles, helping you reduce waste, labor, and replacement costs.
