1. Market Trend: TPU Is Rapidly Replacing PU in Heavy-Duty Wheel Applications

Over the past three years, the industrial wheel market (caster wheels, pallet truck wheels, conveyor wheels) has seen a strong shift from PU to TPU (Thermoplastic Polyurethane).
The main drivers are stricter performance requirements from logistics, warehousing, automation, and robotic systems:

• Higher load capacity
• Continuous 24/7 operation
• Strong surface friction
• Harsh temperature & humidity conditions
• Extreme abrasion demands

TPU delivers 1.5–3× longer lifespan thanks to its exceptional mechanical strength, tear resistance, hydrolysis resistance, and durability.

2. TPU vs. PU: Why TPU Performs Better

2.1. 2–4× Higher Abrasion Resistance

TPU has a well-balanced elastic–crystalline polymer structure, providing outstanding wear resistance on:

• Rough concrete floors
• Metal surfaces
• Wet or oily environments

This is crucial for extending wheel lifetime and reducing maintenance cost.

2.2. Better Load Capacity & Minimal Compression Set

PU often suffers from flat-spotting or permanent deformation when carrying heavy loads for long periods.
TPU, on the other hand:

• Maintains its shape
• Minimizes deformation
• Distributes load evenly
• Reduces vibration during heavy-load operation

2.3. Superior Hydrolysis & Chemical Resistance

TPU is ideal for:

• Cold storage
• Food processing plants
• High-humidity environments
• Areas exposed to oils and chemicals

PU Ester tends to degrade or “break down,” while TPU remains stable.

2.4. Better Grip & Elasticity

TPU offers higher friction, ensuring stronger traction and non-slip performance, especially important for conveyor wheels and AGV robots.

Its elasticity also helps reduce noise and provides smoother wheel movement.

2.5. Easy Processing & Lower Defect Rates

TPU offers:

• Clear melting point
• Stable injection molding performance
• Reduced risk of core separation
• Lower burn defects

This helps manufacturers reduce scrap rate and improve production efficiency.

3. TPU Grades Designed for Heavy-Duty Wheels

3.1. Required Performance for Wheel-Grade TPU

• Shore A: 85–95
• Abrasion: < 60 mm³
• Tear strength: > 80 kN/m
• Low compression set
• Hydrolysis resistance
• Oil & chemical resistance

3.2. TPU Grades Commonly Used (Provided by JM Enterprise)

• Polyester TPU for heavy-load wheels
  → High stiffness, excellent wear resistance, strong traction
• Polyether TPU for humid or cold environments
  → No hydrolysis, no degradation
• Oil-resistant TPU for mechanical shops & logistics environments
• High Abrasion-Resistant TPU for AGV robot wheels & pallet truck wheels

4. TPU Applications in Wheel Manufacturing

✔ Pallet truck / pallet jack wheels
✔ AGV/AMR robot wheels
