HR Molded Foam - Flexible Polyurethane Raw Materials

HR Molded Foam (Flexible) Polyurethane Systems

The PLUSOL-F-201 and PLUSNATE-F-200 series represent Pluskim’s advanced generation of high-strength, flexible polyurethane foam systems.

Developed with precision and formulated using MDI-based technology, these two-component High Resilience (HR) molded polyurethane systems offer superior mechanical properties compared to conventional block foam products.

Their elevated sag factors, improved compression behavior, and optimized hysteresis curves position HR foams as a premium choice for applications that demand both comfort and durability.

Thanks to their unique polymer structure, HR foams provide enhanced energy absorption, long-term elasticity, and excellent recovery characteristics—qualities essential for seating systems, ergonomic components, and comfort-focused industrial applications.

As industries increasingly prioritize user comfort, longevity, and performance reliability, HR molded foams have become a preferred material solution across multiple sectors.

Key Features of HR Molded Polyurethane Foams

HR molded polyurethane foams offer superior resilience, durability, and comfort through enhanced elasticity and optimized cell structure. They provide excellent energy absorption, long-term shape retention, and customizable hardness levels, making them ideal for seating, automotive, ergonomic, and high-performance comfort applications.

High Strength & Long-Term Durability

HR polyurethane foams are engineered to withstand continuous mechanical stress without permanent deformation. Their robust cell structure maintains stability across repeated load cycles, ensuring performance longevity even under intensive daily use.

Superior Comfort & Flexibility

Due to their enhanced energy absorption profile and elastic response, HR foams deliver a higher level of comfort compared to traditional foams. This makes them ideal for seating products where pressure distribution, ergonomic support, and tactile softness are essential.

Customizable Hardness Levels

Both the PLUSOL-F-201 and PLUSNATE-F-200 series can be formulated in a wide range of hardness values. This adjustability allows manufacturers to create products tailored to specific comfort, design, and application requirements.

Cold Molding Application

These systems are optimized for cold molding, enabling efficient low-temperature processing. This not only supports energy savings but also ensures consistent curing behavior, dimensional stability, and reliable production throughput.

Technical Details

These systems feature adjustable formulations, controlled reaction profiles, and a pre-polymer approach that enhances processing stability.

With high sag factors and optimized hysteresis curves, HR molded polyurethane foams deliver consistent mechanical performance, efficient production behavior, and long-lasting durability across various applications.

Formulation Flexibility

Pluskim’s HR foam systems can be tailored to meet various design and performance specifications. Adjustments to viscosity, hardness, reaction profile, and cell structure enable manufacturers to optimize the foam for different industrial scenarios, from automotive seating to high-end furniture applications.

Pre-Polymer Approach

The PLUSOL-F-201 and PLUSNATE-F-200 series are based on a pre-polymer production approach, which ensures better control over reactivity, improved processing consistency, and enhanced foam quality. This method provides a stable and predictable system ideal for mass production and professional molding environments.

High Sag Factor

A higher sag factor is one of the distinguishing characteristics of HR foams. It directly contributes to improved elasticity, comfort, and load-bearing performance. This property enables the foam to compress gently under load while maintaining strong recovery behavior.

Optimized Hysteresis Curves

With improved hysteresis performance, these HR systems minimize energy loss during compression cycles. This means less fatigue over time, making the foam more durable and more resilient—especially important for seating and ergonomic applications where long-term comfort is expected.

Applications of HR Molded Polyurethane Foams

HR molded polyurethane foams are widely used in seating systems, automotive interiors, office and ergonomic furniture, and mattress components.

Their resilience, comfort, and long-term durability make them ideal for applications requiring enhanced support, energy absorption, and reliable performance across diverse comfort and industrial products.

Seating Groups

Ideal for chair and sofa cushions, HR foams offer a premium comfort experience with excellent dimensional stability. Their supportive yet flexible structure makes them a preferred choice for both residential and commercial seating solutions.

Automotive Industry

The automotive sector benefits significantly from HR foam systems in components such as vehicle seats, headrests, armrests, and interior comfort elements.

Their durability and comfort-enhancing properties improve passenger experience while meeting performance standards required by automotive manufacturers.

Ergonomic Products

Office chairs, mattress components, and ergonomic accessories rely on HR foams for balanced support, pressure distribution, and long-term comfort. The resilience of HR technology ensures that these products maintain their form and function under constant usage.
