Non-Marking Polyurethane Wheels for Semiconductor & Industrial Automation

In semiconductor, FPD, solar PV, and precision manufacturing environments, even minor contamination, surface damage, or particle generation can affect product quality and manufacturing yield. As specialists in polyurethane (PU) elastomer R&D and manufacturing, we provide non-marking polyurethane wheels engineered through molecular-level formulation optimization to offer superior protection for highly sensitive surfaces.

Advantages of Non-Marking Polyurethane Wheels

Zero-Marking Assurance: Our specially formulated non-marking polyurethane compounds are designed to minimize surface marks on epoxy, vinyl, tile, and other industrial flooring materials.

Noise Reduction: The inherent elasticity of high-quality polyurethane absorbs vibration and shock, significantly reducing operational noise levels—a critical requirement for quiet work environments like hospitals and office buildings.

Exceptional Durability: While softer than metal, our polyurethane treads are engineered for high load-bearing capacity and long-term wear resistance, ensuring your wheels don’t develop flat spots under heavy static loads.

Chemical & Moisture Resistance: Designed to withstand daily maintenance cycles, our wheels resist oils, greases, and standard cleaning chemicals, ensuring they remain resilient in demanding commercial environments.

Particle Generation: Low-particle-generation polyurethane materials help maintain cleanroom standards by reducing abrasion debris during continuous operation, suitable for ISO 5 / Class 100 cleanroom environments

Electrostatic Control: Conductive and anti-static polyurethane formulations are available to prevent electrostatic discharge (ESD) risks in sensitive electronic manufacturing environments.

Precision Movement: Advanced PU elastomer technology provides excellent dimensional stability, low rolling resistance, and smooth operation for automated material handling systems.

Applications for Non-Marking PU Wheels

Our non-marking polyurethane caster wheels are widely specified across a variety of sectors where floor aesthetics and performance matter:

1. Semiconductor & Electronics Manufacturing Equipment

Semiconductor manufacturing requires extremely high standards for cleanliness, precision, and contamination control. Wheel materials used in cleanroom automation systems must minimize particle generation, prevent surface damage, and maintain stable performance during continuous operation.

Non-marking polyurethane wheels are widely applied in:

FOUP/Pod stockers

Reticle stockers

OHT (Overhead Hoist Transport) systems

Automated material handling equipment (AMHS)

Cleanroom AGVs and RGVs

Wafer transportation systems

2. Flat Panel Display (FPD) Manufacturing

Flat panel display production involves the handling of large and fragile glass substrates, where even minor scratches, vibration, or contamination can affect product quality.
