• Polyurethane is polymer material that is
popular in many applications for its:
– Toughness
– Abrasion Resistance
– Cut and Tear Resistance
– Ease of Processing
– Versatility

3. Sunray-Inc.com
• Polyurethane is extremely versatile and can
be formulated a number of ways.
• Hardness, size, chemical resistance and shape
can all be formulated differently, depending
on the application.
• There are a number of things to consider
when choosing the right polyurethane
formulation.

• Hardness (Durometer)
• Compression
• Resilience
• Abrasion Resistance
• Flex Fatigue
• Load Capacity
• Resistance to Solvents
• Stability

• Idler & Drive Wheels
• Used In Industrial Manufacturing:
– Low Compression to Reduce Flat Spotting.
– Low Heat Build Up to Run at Higher Speeds.
– High Resilience For Continuous Operation.

7. Sunray-Inc.com
• U-groove & V-groove Wheels
• Used For Track, Rail And Roller Applications
• Similar Formulation To Non-grooved Wheels:
– Low Compression
– Low Heat Build Up
– High Resilience

8. Sunray-Inc.com
• Designed For Demanding Applications
• Hard Outer Tread For Durability
• Softer Inner Core Allows the Wheel to Flex,
Protecting Delicate Materials

9. Sunray-Inc.com
• Used In Robotic Stacking Operations
(AGV Equipment]
• Hardness Is Dependent On Material Being
Handled
• Formulated To Be Extremely Durable For
Repetitive Operations

10. Sunray-Inc.com
• Used On Amusement Park Rides
• Manufactured From Two Formulations of
Polyurethane:
– Hard Inner Core
– Soft Resilient Outer Tread
– Water-Resistant
– Provides Shock Absorption

• Idler & Drive Rollers
• Used in manufacturing when a greater
load distribution is required.
• Similar formulation as Polyurethane
Wheels.
– Low Compression
– Low Heat Build Up
