These solid polyurethane rods offer an impressive combination of tensile strength (30-50 MPa) and flexibility (elongation at break: 300%-500%), making them ideal for demanding industrial applications. Engineered for high cut and impact resistance, they endure intense operational conditions without significant wear, ensuring enhanced longevity and durability.

Versatile Application Options

PU rods are commonly used for fabricating machinery parts, gaskets, seals, cushion pads, and shock absorbers. Thanks to their oil resistance and low water absorption, they are highly suitable for both dry and wet environments. Their customizable dimensions make them a practical solution across diverse industries.

Custom Manufacturing & OEM Service

Our PU rods are available in a wide range of diameters and lengths to suit specific requirements. Both cast and injection molding processes are utilized to produce rods with a smooth, non-porous finish. OEM services are available to facilitate tailored solutions for dealers, distributors, retailers, and end-users across India.

FAQ's of PU Rod:

Q: How are PU rods with hardness 70A-95A Shore manufactured?

A: PU rods are typically produced using either casting or injection molding processes. These methods help achieve a consistent, non-porous, and smooth surface finish, ensuring the products meet demanding industrial specifications for mechanical properties and reliability.

Q: What makes PU rods suitable for industrial applications?

A: With high tensile strength (30-50 MPa), impressive elongation (300%-500%), excellent impact and cut resistance, and low compression set, PU rods withstand heavy loads, repeated stress, and harsh operating environments, making them ideal for machinery parts and engineering components.

Q: Where can PU rods be used effectively?

A: PU rods are highly effective in applications such as machinery parts, gaskets, cushion pads, seals, and shock absorbers. Their oil resistance and minimal water absorption make them suitable for use in both wet and dry industrial settings.

Q: What benefits does a PU rod provide over traditional rubber or plastic rods?

A: Compared to many rubber or plastic alternatives, PU rods offer higher tensile strength, better abrasion and cut resistance, lower compression set, and superior impact resistance, resulting in longer service life and reduced maintenance requirements.

Q: When should one choose PU rods with high hardness?

A: High-hardness PU rods (above 90A Shore) are recommended when the application requires superior wear, abrasion, or cut resistance, such as in heavy-duty gaskets, seals, or anti-vibration components.

Q: How can custom sizes of PU rods be ordered?

A: Custom PU rod sizes can be requested by specifying required diameters (10 mm to 300 mm) and lengths (300 mm to 1,000 mm). OEM services are available to accommodate specific client and industry requirements across India.

Q: What is the main process behind ensuring the durability and performance of PU rods?

A: The use of industrial-grade polyurethane with over 99% purity, combined with precise molding techniques, ensures excellent durability, consistent mechanical properties, and a smooth surface finish for every PU rod manufactured.
