Polyurethane Manufacturers
Last updated: January 2026
This directory lists 103 polyurethane manufacturers across the United States, from specialized custom cast urethane shops handling low-volume industrial components to high-capacity facilities performing complex Reaction Injection Molding (RIM) for automotive and medical sectors.
Buyers typically engage these manufacturers to solve critical problems requiring unique material properties: seeking superior abrasion resistance for industrial rollers, specific compression set for durable seals, controlled impact absorption for protective padding, or consistent elongation for flexible diaphragms. Achieving these specifications often demands precise control over the polymer's cross-linking and cellular structure.
The supplier landscape ranges from dedicated custom casters, who excel at short runs and intricate designs using relatively inexpensive tooling, to foam fabricators specializing in cutting and shaping open-cell and closed-cell foams. Further upstream are molders focusing on high-volume processes like RIM or Liquid Injection Molding (LIM), alongside extruders producing continuous profiles and films from Thermoplastic Polyurethane (TPU). Each type brings distinct advantages in terms of material breadth, scale, and tooling investment.
To ensure a smooth engagement, buyers should come prepared with detailed specifications including required Shore hardness, tensile strength, tear strength, and any environmental resistance needs (e.g., UV, chemical exposure). Understanding the expected annual volume and acceptable lead times for both tooling and production will also significantly help manufacturers provide accurate quotes and suitable process recommendations.

How to Choose a Company
- Validate Process-Specific Expertise: Don't just ask if they "do polyurethane." Inquire if they have proven experience with your specific required process, such as high-pressure Reaction Injection Molding (RIM) for complex, high-volume enclosures, or low-pressure casting for large, thick-sectioned elastomer parts where post-curing is critical.
- Scrutinize Material Formulation Capabilities: For custom applications, verify their ability to formulate specific urethane chemistries to meet detailed property requirements like a precise Shore A or D hardness, specific compression set values, or critical elongation and tear strength thresholds, backed by internal lab testing.
- Understand Tooling Impact and Ownership: Clarify the type of tooling required for their process (e.g., soft tooling for cast urethanes vs. hard steel/aluminum for RIM or LIM) and discuss tooling lead times, costs, and ownership. A common gotcha is not understanding the amortization of expensive hard tooling over lower-volume runs.
- Assess Quality Control & Compliance: For sensitive applications, confirm they perform relevant material testing (e.g., ASTM D3574 for flexible cellular materials) and can provide certifications like UL 94 for flammability or adhere to automotive standards such as FMVSS 302 if applicable.
- Evaluate Production Scale & Demold Cycle Management: For production runs, confirm they can scale from your prototype needs to your production volumes, and critically, inquire about their typical demold times and how they manage these cycles to meet your delivery schedule without compromising part integrity.
- Red Flag: Vague Pot Life Management: Be wary of manufacturers who can't clearly explain how they manage exothermic reactions, pot life, and cure cycles, especially for thicker sections or complex geometries. Poor control here can lead to inconsistent material properties, internal voids, or delayed production.

Frequently Asked Questions
What's the critical difference between cast urethane and Reaction Injection Molding (RIM) for my custom part?
Cast urethane involves pouring pre-mixed liquid polyurethane into a mold and allowing it to cure, ideal for lower volumes, larger/thicker parts, and specialized material properties with softer tooling. RIM, conversely, injects two liquid components under pressure into a closed mold where they react and cure, enabling faster cycle times, finer detail, thinner walls, and higher volumes with more robust, often more expensive, tooling. Your part's geometry, volume, and tolerance requirements will dictate the most suitable process.
How do I accurately specify Shore hardness for my polyurethane component, and why does it matter beyond a single number?
Shore hardness (e.g., Shore A, Shore D) indicates resistance to indentation, but it's crucial to specify the range and test method (e.g., ASTM D2240). Beyond the number, consider the material's elastic modulus, compression set, and tear strength; a high Shore A might still deform under constant load if the compression set is poor. Discuss your application's specific loading conditions and expected deformation with the manufacturer to ensure the material performs as intended, rather than just meeting a static hardness value.
What impact do a manufacturer's tooling capabilities and demold time have on my project timeline and cost for custom polyurethane parts?
Tooling type significantly affects initial cost and lead time: soft silicone or epoxy molds for casting are cheaper and faster but wear quickly, while hard aluminum or steel tools for RIM are expensive but durable for high volumes. Demold time – the period before a part can be removed from the mold without deforming – directly dictates cycle time. A longer demold time means fewer parts per shift and higher unit costs. Understand how the manufacturer balances tooling investment, material formulation (which affects demold time), and production efficiency to meet your cost and delivery targets.
For flexible polyurethane foam, what should I look for regarding open-cell versus closed-cell structures?
The cell structure dictates key performance characteristics. Open-cell foams have interconnected pores, making them excellent for sound absorption, thermal insulation, and breathability, but they absorb water and are less supportive. Closed-cell foams have sealed, discrete cells, providing superior waterproofing, higher structural rigidity, better energy absorption (impact), and often greater resistance to chemicals, but they are less breathable and can feel firmer. Your application's need for insulation, sound dampening, water resistance, or impact protection will guide the choice.
What kind of material test data or certifications should I request for a critical polyurethane application like an automotive component or medical device?
For critical applications, always request a Certificate of Conformance (CoC) for the material batch. Beyond that, ask for specific test reports, which might include tensile strength, tear strength (e.g., ASTM D624), elongation, compression set (e.g., ASTM D395), density, and specific gravity. For automotive, confirm compliance with standards like FMVSS 302 (flammability). For medical, inquire about biocompatibility testing and adherence to relevant ISO standards or FDA guidelines, ensuring traceability of raw materials and consistent batch quality.
