We are a leading China-based manufacturer and supplier of urethane (also called PU or polyurethane) liners for chute and hopper. Our precision casting process ensures each liner meets strict tolerance standards, delivering exceptional wear resistance for high-abrasion environments. Made from high-grade polyurethane, our liners outperform rubber and steel, with a service life proven to exceed 4 years in tough conditions.

Our urethane chute liners and urethane hopper liners serve diverse industries worldwide. From mining crushers and aggregate conveyors to seaport and agricultural grain handlers and construction concrete mixers, our liners prevent equipment from abrasive materials, corrosive substances, and impact damage.

Application of Urethane Liners

- Mining: Protect ore transport chutes from rock abrasion

- Agriculture: Line grain hoppers for seamless material flow

- Construction: Shield concrete mixer chutes from aggregate wear

- Waste Management: Line debris hoppers to resist corrosion

- Food Processing: FDA-grade liners for material handling

Advantages of Urethane Liners

- Excellent Wear Resistance: Polyurethane is a wear-resistant material , nearly 10 times that of rubber.

- Corrosion & High-Temperature Resistance: Polyurethane elastomer offers excellent corrosion and rust prevention performance.

- Aging Resistance & Long Service Life: Polyurethane elastomer has good anti-aging properties, which can extend the service life of conveyor hoppers.

- Superior Shock Absorption & Cushioning: Polyurethane provides excellent shock absorption and cushioning, reducing noise and vibration during conveyance and improving workplace quality.

- Dust Pollution Prevention: The integrated top-to-bottom design prevents dust diffusion when materials fall from heights, reducing pollution.

- Adjustable Density : The density of polyurethane elastomer is adjustable. It can be molded into conveyor hoppers of various shapes according to specific density requirements.

- Various Color Options: We offer a variety of colors, enabling the production of conveyor hoppers that are visually appealing, durable, and corrosion-resistant.

Case Study of Urethane Liners ?

This polyurethane hopper is used in very cold condition, where the ambient temperature generally ranges from -40℃ to 40℃ (often around -40℃). It is applied for port material conveyance—ports in this region are located near oceans or bays, resulting in high air humidity (relative humidity often exceeds 70% or even higher). The marine moisture in the port environment and persistent humid climate, combined with salty marine conditions, easily cause corrosive damage to port facilities and equipment.
