Why Polyurethane for Shock Tools?
-
Exceptional Abrasion & Wear Resistance
Withstands repeated compression, impact loading, and abrasive drilling environments without tearing or deforming. -
Chemical & Fluid Compatibility
Resists degradation from drilling fluids, oils, grease, smog, and ozone—conditions that cause natural rubber to fail prematurely. -
Low Compression Set
Maintains thickness and elasticity even after thousands of high-force cycles, ensuring consistent shock performance. -
Dielectric & Non-Magnetic Properties
Safe for use around MWD/LWD systems and sensitive electronic assemblies. -
Bondability to Metals & Composites
Allows hybrid or multi-material designs when required by tool engineering. -
Precision Durometer Control
Hardness can be engineered to match your exact shock pulse or energy absorption profile. -
Fast, Reliable Production
ISM casts and machines polyurethane in-house for rapid prototyping, short production runs, and consistent quality—without offshore delays. -
A Legacy of Performance
Backed by five decades of ISM expertise in manufacturing trusted components for the drilling and oilfield industry.
These characteristics make cast urethane the ideal choice for high-cycle, high-impact, vibration-critical applications.
Polyurethane Shock Components Built for Extreme Downhole Demands
Our polyurethane shock disks and rings are engineered to absorb energy, soften impact loads, and reduce vibration transfer within drilling tools and industrial systems. These components help protect sensitive assemblies such as:
- Shock tools & drilling jars
- MWD/LWD electronic housings
- Tool joints and threaded connections
- Measurement instrumentation
- High-cycle downhole mechanisms
Suitable for any industrial machinery, automation systems, and equipment where shock/vibration protection extends component life.
Mining Vibration & Isolation Products
Mining operations rely heavily on vibrating equipment — shaker tables, screening decks, feeders, crushers, and processing systems. These environments create constant shock loading, dynamic stress, and structural fatigue.
Our urethane vibration products are used in:
-
Shaker tables
-
Vibrating screens and screen decks
-
Feeders and hoppers
-
Crusher support systems
-
Pump skids and structural mounting points
-
Material handling equipment
Whether isolating vibration from structural steel or cushioning impact at contact points, our components are engineered for performance in harsh environments.
Vibration Bumpers
Custom-molded bumpers designed to absorb shock loads and reduce frame damage in shaker tables and vibrating systems.
Isolation Mounts & Pads
Durable urethane mounts that reduce vibration transfer to surrounding equipment and structures.
Impact Cushions & Stops
Replaceable urethane components that protect high-impact zones from metal-to-metal damage.
Structural Protection Components
Custom-cast urethane elements designed to protect mounting brackets, frames, and connection points.
Conveyor Belt Rollers & Urethane-Coated Rollers
Precision-molded and bonded urethane rollers designed for conveyor systems in mining and material handling applications. Urethane reduces vibration, minimizes belt wear, improves traction, and extends service life in abrasive environments.
Because Industrial Screen & Maintenance (ISM) casts, cures, and CNC-machines polyurethane entirely in-house, we maintain precise control over material consistency, durometer accuracy, dimensional tolerances, and overall performance. Our integrated manufacturing approach allows us to produce complex geometries, precision OD/ID fits, grooves, and custom profiles—ensuring every component meets the demanding requirements of oilfield and industrial shock applications.

Polyurethane hardness affects shock response
- 60A–80A: Softer, ideal for energy absorption and cushioning.
- 85A–95A: Stiffer materials for high-impact loads, downhole shock tools, and drilling jar components.
- Shore D Options: For extreme rigidity or hybrid assemblies.

FAQs Frequently Asked Questions
What do urethane shock disks and rings do?
They absorb impact energy and dampen vibration to protect drilling tools, electronics, and mechanical assemblies.
How does polyurethane compare to rubber or metal springs?
Polyurethane resists abrasion, oil, and chemical degradation and maintains shape under repeated cycles, outperforming rubber in oilfield applications.
Can you match an existing part?
Yes. Send a sample or drawing, and we’ll match or improve the geometry and material.
Is polyurethane suitable for downhole environments?
Yes. We use formulations engineered for hydrocarbons, drilling fluids, temperature fluctuations, and abrasive conditions.
Do you support small orders or prototypes?
Absolutely, from one-offs to full production.
What temperature can urethane safely operate in?
A working temperature under a consecutive 220 degree Fahrenheit is recommended.
