PU vs. PP Chair Casters: Why Material Choice Matters for Your Seating Product Line

By Enjoying Go Co., Ltd.

In the development of office and commercial seating, caster material is not just a manufacturing detail—it’s a crucial factor that directly impacts end-user comfort, floor protection, long-term product value, and brand reputation.

Among the most commonly used materials are PU (Polyurethane) and PP (Polypropylene). Though similar in appearance, these materials offer very different performance characteristics. This guide is designed to help procurement professionals, designers, and furniture manufacturers make the right decision based on use case, user needs, and quality expectations.


PU Casters – The Quiet, Floor-Friendly, High-End Choice

Polyurethane is a premium material known for its elasticity, excellent wear resistance, and noise reduction—making it a popular choice for executive office chairs, conference room seating, and ergonomic workplace solutions.

Advantages of PU Casters:

  • Smooth, silent rolling → Ideal for quiet office spaces, healthcare environments, or meeting rooms

  • Floor protection → Reduces scratching and scuffing on wooden or luxury vinyl floors

  • Long-term durability → Maintains performance over time even with frequent use

Maintenance Notes:

  • Avoid excessive moisture or direct sunlight

  • Clean with a damp cloth or disinfectant wipe—do not soak or wash with water

Professional Tip:
→ Choose "Single-Shot Injection PU Casters" – this advanced manufacturing process bonds PU and nylon into one seamless unit, minimizing the risk of delamination and significantly extending the caster’s service life.


PP Casters – A Budget-Friendly Option for Short-Term or High-Turnover Projects

Polypropylene is a cost-efficient plastic material commonly used in mass-produced furniture for educational, industrial, or budget office environments.

Advantages of PP Casters:

  • Affordable → Ideal for cost-sensitive bulk orders or temporary seating solutions

  • Resistant to moisture and corrosion → Performs well in humid storage or workshop settings

  • Lightweight → Easier to assemble, ship, and replace

Limitations of PP Casters:

  • Noisy rolling and limited shock absorption

  • Tends to scratch delicate flooring surfaces

  • Becomes brittle in cold weather and has lower overall durability compared to PU


Application Scenarios and Material Recommendations:

Use Scenario Recommended Caster Material Key Reason
Executive Office Chairs PU (Single-shot injected) Quiet, smooth, and floor-safe with premium appeal
Budget-Friendly Seating PP Casters Cost-effective and sufficient for temporary setups
Educational or Industrial Nylon (PA6) or PU Casters Focus on durability and weight-bearing capacity
Healthcare Facilities PU Casters (Low Noise) Smooth rolling and hygienic for quiet environments

Why Caster Material Isn’t Just a Price Tag

Too often, the choice of caster is treated as a low-priority decision during production. But poor rolling performance, noise, or floor damage can become major pain points for end users—and ultimately affect product reviews and brand perception.
