What Is CPU Cast Polyurethane Elastomer? High-Performance Solutions For Industrial Applications

Dec 19, 2025 Leave a message

Cast Polyurethane Elastomer, commonly known as CPU, is one of the most versatile and high-performance elastomer materials used in modern industrial applications. Compared with TPU and rubber, CPU polyurethane elastomer offers superior mechanical strength, excellent abrasion resistance, outstanding load-bearing capacity, and long service life, making it a preferred choice in demanding environments.

Understanding CPU Cast Polyurethane Elastomer

CPU elastomer is produced through a liquid casting process, where prepolymers react with curing agents and are poured into molds. This method allows the production of large, thick, and complex polyurethane parts that cannot be achieved through injection molding. CPU materials can be tailored in hardness from Shore A 30 to Shore D 80, meeting diverse application requirements.

Key properties of cast polyurethane elastomer include:

Excellent abrasion and wear resistance

High tensile strength and tear resistance

Superior impact resistance

Outstanding oil, grease, and chemical resistance

Excellent vibration damping and noise reduction

These characteristics make CPU polyurethane elastomers ideal for replacing rubber, metal, and plastic in many industrial uses.

Main Applications of CPU Polyurethane Elastomers

CPU elastomers are widely used across multiple industries:

Mining & Quarrying: polyurethane screens, liners, hydrocyclones

Material Handling: polyurethane rollers, conveyor components, scraper blades

Industrial Machinery: bushings, seals, gaskets, couplings

Construction Equipment: wear pads, shock absorbers, impact buffers

Oil & Gas: sealing elements, pipeline supports

Thanks to their excellent wear resistance and load capacity, CPU polyurethane products significantly reduce downtime and maintenance costs.

Advantages Over Rubber and TPU

Compared with traditional rubber:

CPU elastomer lasts 3–5 times longer

Better resistance to cutting and tearing

Maintains elasticity under heavy load

Compared with TPU:

CPU is suitable for thicker and heavier parts

Higher customization flexibility

Better performance in harsh working environments

This makes CPU cast polyurethane the optimal solution for heavy-duty industrial applications.
