How to choose the right PIR System for real production needs in insulated panel manufacturing?

Puroxen 1800 vs 1750 — one market, different needs

Although PIR systems have become the industry standard in the production of metal-faced insulated panels, manufacturers are increasingly facing another important decision — selecting a system that best matches their production requirements and market expectations.

Today’s sandwich panel market is far more complex than it was just a few years ago. For some manufacturers, achieving the lowest possible thermal conductivity remains the key objective in order to produce panels with the highest insulation performance. Others focus primarily on process stability, a wide processing window, and the reliability of day-to-day production. An increasing number of producers are also paying close attention to production economics, line efficiency, and opportunities for cost optimization.

This is precisely why Purinova has developed different PIR systems designed to address specific market needs and various production models within the sandwich panel industry.

Two different approaches to PIR panel production

To meet the diverse needs of sandwich panel manufacturers, Purinova continues to develop a portfolio of PIR systems tailored to different production models and market expectations.

Puroxen 1800 was developed for manufacturers seeking the highest insulation performance, an exceptionally wide processing window, and maximum production stability. Puroxen 1750, on the other hand, addresses the needs of customers looking for the right balance between process stability, product performance, and production economics.

Although both systems belong to the group of advanced PIR technologies for insulated panel production, each was designed with different technological priorities and production approaches in mind.

Puroxen 1800 — a Premium-Class System

Puroxen 1800 is the most advanced PIR system in Purinova’s portfolio, developed for manufacturers seeking the highest insulation performance and maximum production process stability. The system was created in response to the needs of the most demanding customers, for whom not only laboratory results matter, but also production reliability, consistent quality, and the long-term stability of panel properties. It is primarily chosen by companies that build their competitive advantage on the quality of the finished product and the long-term trust of end users.

Puroxen 1800 is the result of many years of market experience and close cooperation with sandwich panel manufacturers. Its refined formulation combines very low thermal conductivity with high cell stability, excellent dimensional stability, and strong adhesion to metal facings.

One of the system’s greatest advantages is its wide processing window. In practice, this translates into greater day-to-day production stability and reduced risk of issues caused by fluctuations in ambient temperature, differences in operator performance, or temporary process deviations. This is why Puroxen 1800 is often selected by manufacturers seeking maximum process reliability and a lower risk of product claims.

The advanced performance of the system is primarily driven by Purinova’s formulation expertise. The careful selection of surfactants, catalysts, and additives influences not only the final panel properties but also the stability of the entire production process.

Foaming technology is another key factor in premium PIR systems. Puroxen 1800 has been developed to work with virtually all foaming technologies commonly used in the market — from conventional pentane-based blowing agents, such as n-pentane, cyclopentane, and cyclopentane/isopentane blends, to modern next-generation HFO (hydrofluoroolefin) blowing agents.

This compatibility with a wide range of blowing agents allows manufacturers to optimize the system according to the specific requirements of their production line and the desired panel performance. The choice of blowing agent affects not only the production process itself, but also the final thermal conductivity and long-term stability of the system.

Puroxen 1800 has been on the market for more than 10 years and has been proven in industrial use by numerous sandwich panel manufacturers. Thanks to its high process stability and consistent quality, the system is characterized by a very low level of customer claims compared with many solutions available on the market.

Puroxen 1750 — the balance between performance and production economics

Puroxen 1750 was developed in response to the needs of sandwich panel manufacturers seeking a stable and reliable PIR system while maintaining favorable production economics. The system was designed for customers who do not necessarily require the lowest possible thermal conductivity values, but instead focus on stable processing, efficient production, and consistent panel performance.

Puroxen 1750 was not created as a simplified version of a premium system, but rather as a solution tailored to a different production model and a different set of market requirements. In practice, this means a distinct formulation approach designed for production lines where the key objective is to combine process stability with cost optimization.

The system has been developed to deliver very good fire and mechanical performance while maintaining a wide and stable processing window. This allows manufacturers to sustain high production line efficiency while reducing the risk of technological issues during day-to-day operations.

Puroxen 1750 is particularly well suited to markets where not only the quality of the system itself matters, but also the overall economics of the production process and the ability to remain competitive while maintaining consistent finished product quality.

Solutions supporting sustainable development

Sustainability-related considerations are playing an increasingly important role in the construction industry. Investors and manufacturers are paying attention not only to the technical performance of finished products, but also to the origin of raw materials, the use of recycled content, and the environmental impact of products throughout their lifecycle.

In response to these market expectations, Purinova continues to expand its portfolio of solutions designed to support customers in achieving their sustainability goals. Alongside standard PIR systems, we develop technologies focused on increasing the share of recycled raw materials and reducing the use of selected chemical substances within formulations.

Particular emphasis is placed on solutions based on secondary raw materials. Purinova develops technologies that primarily utilize materials recovered from waste generated during the production and processing of PIR foams. The use of PIR dust as a raw material for new formulations allows valuable material to be reintroduced into the production cycle and represents a practical example of circular economy principles in action. Our sustainable product portfolio also includes formulations incorporating recycled PET-based raw materials, which have long been recognized and utilized within the polyurethane industry.

Purinova’s portfolio also includes halogen-free systems. This means that the formulations do not contain halogenated flame-retardant additives used in some traditional solutions. Such an approach is increasingly recognized as one of the key directions in the development of modern insulation materials, responding to growing market expectations related to sustainability, product stewardship, and future environmental regulations.

Importantly, modern sustainable solutions are no longer merely a complementary offering. Thanks to carefully engineered formulations, they can deliver performance comparable to traditional systems based on petrochemical raw materials, while maintaining excellent thermal insulation properties, mechanical performance, and processing stability. This allows sandwich panel manufacturers to pursue their sustainability objectives without compromising the quality, process reliability, and production efficiency expected from modern PIR systems.

Technological support as part of the System

In modern sandwich panel manufacturing, the PIR system itself is often only one part of the overall technological process. Equally important today is the know-how behind the formulation, quality consistency, and day-to-day production support.

Panel manufacturers know their production lines, capabilities, and limitations better than anyone. Purinova’s role is to understand the chemistry of the entire process and support customers in achieving stable, safe, and repeatable production. Every production line operates under different conditions — varying in length, speed, equipment configuration, and process characteristics — which is why implementing a PIR system often requires an individual technological approach.

Technical support extends far beyond the initial start-up phase. It also includes further process optimization, sample analysis, and ongoing quality monitoring. An equally important aspect is the selection of the right formulation, catalyst packages, and processing parameters tailored to a specific production line.

Another key element of technical support is ensuring the consistency of the supplied system. Even the most optimized production process can become problematic if raw material properties vary from one delivery to another. For panel manufacturers, consistency of system parameters has a direct impact on product quality, process repeatability, and overall production efficiency.

Maintaining this consistency is supported by an extensive laboratory infrastructure and a multi-stage quality control process covering both raw materials and system components used in PIR production. Supplier qualification, raw material verification, and continuous monitoring of production processes help minimize the risk of unwanted deviations and ensure customers receive a stable and reliable product.

In practice, this means that a modern PIR system is much more than just a chemical formulation. It is also a guarantee of consistent quality, technical support, and expertise that helps customers achieve reliable day-to-day production.
