INDUSTRIES SERVED: Automotive , Material Handling, Agriculture, Manufacturing & Industrial Machinery
Shanghai Pepsen is the earliest manufacturer of polyurethane rods（also known as PU rods, urethane rod, PU rubber rod）in China. With many stocked molds and much experience, we are capable of supplying various PU rods with customized diameter , length, hardness, colors and formulations.
Polyurethane rods are usually used to produce bushes, impact pads, damper, buffer, bumper, pads, spacers, spring and many more. They serve diverse industries: automotive (for suspension bushings), material handling & mining (strips, rollers and wheels), and manufacturing & industrial machinery (as machine parts like bump stops, vibration isolators, wear pads. They can also be used for hydraulic seal machining.
| Custom Parameter | Available Options | Target Applications |
|---|---|---|
| Diameter | 3mm - 500mm (standard & custom sizes) | Automotive suspension bushings, machinery wear pads |
| Hardness (Durometer) | 20A (soft) - 80D (hard) | Medical device components, aerospace lightweight spacers |
| Length | 100mm - 3000mm (cut-to-length or full rods) | Food processing equipment parts, industrial spacers |
| Custom polyurethane formulations | Anti-static, UV-resistant, FDA-compliant | Electronics industry rods, outdoor machinery parts, food-contact components |
- Automotive Industry:
Used for steering system components to absorb bumps, providing a quieter and smoother ride. Also used for seals and other parts requiring durability and flexibility.
- Material Handling & Mining:
Ideal for components like wear strips, rollers, and chute liners due to their high abrasion and impact resistance when handling abrasive materials like coal, sand, and ore.
- Manufacturing & Industrial Machinery:
Employed as machine parts like waer pads, bump stops, vibration isolators, and bushings to absorb shock, reduce vibration, and extend the life of equipment.
- Agriculture:
Found in applications such as plow wear strips and other components requiring strong wear and corrosion resistance.
- Transportation:
Used in various vehicles and marine applications for their durable and weather-resistant properties.
- Durable: superior wear resistance to ordinary rubber, withstanding frequent friction and impacts. Its service life is 3-5 times longer than traditional rubber rods, reducing frequent replacement costs.
- Environmental Adaptability: Resistant to oil and chemical corrosion (e.g., acid-alkali solutions), and maintains elasticity in the temperature range of -40℃ to 120℃, suitable for high and low-temperature working conditions.
- High Elasticity & Cushioning: Features a rebound rate of over 70%, effectively absorbing vibrations and dispersing pressure to prevent equipment damage from impacts.
- Weather Reistance: Withstands sunlight and weathering for outdoor durability.
- Lightweight & Easy to Process: Weighs only 1/3 of metal rods, and is easy to cut and drill, making assembly easier and reducing the overall weight of equipment.
Experience
Pepsen has manufactured polyurethane solid rods since 1996, building rich field experience and technical expertise.
Extensive Stocked Molds
A large stock of molds cuts costs and lead times for both custom and standard-sized polyurethane rods.
Flexible Customization
Beyond standard shapes, Pepsen offers custom colorants, multiple Shore hardnesses, and rods tailored to specific application needs.
Strict Quality Control
Tight oversight of mixing, demolding, and post-curing ensures consistent quality and performance of every rod.
In-House Machining
Pepsen provides in-house machining to turn urethane rods into tight-tolerance parts, delivering comprehensive solutions.

Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
All of products with 3-6 months guarantee (except very frequently wearing parts).
We will response in 24 hours with solutions such as replacement or reworking.
We have dedicated personnel to sort out and maintain molds regularly.
20,000 times for compressions molds and 30,000 time for casting molds
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
