Polyurethane (PU) Sheet is a high performance engineered material, renowned for its superior durability and versatility that outperforms traditional rubber and plastics. It boasts excellent abrasion, impact and chemical resistance, capable of withstanding oils, solvents and harsh environments while maintaining flexibility even under extreme temperatures (-30℃ to 90℃).
With a wide hardness range (40A to 70D) and customizable sizes, thicknesses and colors, it adapts to diverse industrial, commercial and automotive applications. Machinable and easy to process, it is ideal for linings, gaskets, shock absorbers, conveyor components and vibration dampening pads.
Crafted with strict quality standards, our PU Sheet offers long service life, good elastic memory and load bearing capacity, making it a reliable choice for high-wear scenarios and custom engineering needs.
Applications
1. Industrial: Conveyor belt linings, mechanical table tops
2. Construction: Sealing gaskets, stair treads
3. Civil: Shoe sole liners, yoga mats, floor mats
4. Food/Medicine: Processing table tops, contact sheets
5. Equipment: Shock-absorbing gaskets, precision instrument buffers
