Advanced Polymer Solutions for Data Centers: Materials, Fluid Handling, and Thermal Management for the AI Era
Quick Answer
Data centers built for AI and high-performance computing rely on fluoropolymers — primarily PFA, PTFE, FEP, and PVDF — for fluid-handling and cooling-loop components, paired with silicone, EPDM, or TPV/TPE seals for leak prevention. These materials are chosen for chemical resistance to coolants, continuous-use temperatures up to 500°F (260°C), and long-term dimensional stability under constant thermal cycling. PC/ABS and reinforced thermoplastics handle high-density cable management and routing. Pexco manufactures Altaflo® fluoropolymer tubing, Insultab® heat shrink products, custom extruded profiles, and precision-molded seals and gaskets for each of these application areas. Rigid thermoplastic piping systems such as PVC, CPVC, PVDF, and PFA also support facility-level coolant, water, and specialty fluid distribution where corrosion resistance, chemical compatibility, and long-term reliability are required.
The Future of Data Centers Depends on Materials Innovation
Artificial intelligence, machine learning, cloud computing, and edge processing are transforming the global data center industry. As computational demands continue to increase, operators are building larger, denser, and more power-intensive facilities than ever before. Traditional air-cooling architectures are reaching their practical limits, forcing a rapid shift toward liquid cooling systems, advanced thermal management strategies, and higher-performance infrastructure materials.
While processors, servers, and networking equipment often receive the most attention, the materials that support these systems play a critical role in data center reliability, efficiency, and uptime. Fluid handling systems, cooling loops, cable management infrastructure, seals, gaskets, and electrical protection components must operate continuously in demanding environments where downtime is unacceptable.
In addition to flexible tubing, modern data centers rely on rigid thermoplastic piping systems to distribute cooling water, treated process fluids, and specialty coolants throughout the facility. Materials such as PVC, CPVC, PVDF, and PFA can provide corrosion resistance, long service life, lower weight than metal alternatives, and compatibility with demanding cooling and fluid-handling environments.
Modern data centers require materials that can:
- Withstand continuous thermal cycling
- Resist chemical degradation from advanced coolants
- Support high-density cable routing
- Maintain dimensional stability
- Meet stringent flame and safety standards
- Enable scalable, modular facility designs
- Deliver long-term reliability with minimal maintenance
As a North American leader in engineered polymer solutions, Pexco provides Altaflo® fluoropolymer tubing, Insultab® heat shrink products, custom extrusions, machined components, molded parts, seals, and thermal management solutions that help data center operators, OEMs, and infrastructure designers meet these challenges.
Pexco products map directly to the four core infrastructure categories where material performance is most critical:

- Insultab® Heat Shrink Tubing for wire identification, insulation, and abrasion protection in high-density environments
- Custom Extruded and Molded Seals and gaskets for leak-critical liquid cooling assemblies
Why Are Data Centers Changing So Quickly?
The rise of AI has fundamentally altered the design requirements for data center infrastructure.
Traditional enterprise data centers were designed around server racks drawing roughly 6 to 15 kW. Today’s AI training clusters and high-performance computing (HPC) systems are pushing density to 30–40 kW per rack as a baseline, and the latest GPU platforms — including NVIDIA’s GB200 NVL72 racks — are reaching 120 kW or more in a single rack. That is several times the thermal load of a traditional enterprise rack, concentrated in the same physical footprint.
These increased power densities create three significant challenges:
1. Thermal Management
Heat has become one of the largest constraints on data center performance.
Modern AI racks often exceed the cooling capabilities of conventional air-cooled systems, driving adoption of:
- Direct-to-chip liquid cooling
- Rear-door heat exchangers
- Immersion cooling systems
- Hybrid cooling architectures
- Advanced coolant distribution networks
Industry market research projects the global data center liquid cooling market to grow from roughly $6.6 billion in 2025 to nearly $29.5 billion by 2033 — a clear signal of how quickly operators are moving away from air-cooled architectures.
2. Infrastructure Density
Organizations are deploying more computing power into smaller footprints.
This trend requires:
- Higher-density fiber routing
- Improved cable management
- More efficient airflow pathways
- Modular containment systems
- Compact fluid distribution assemblies
3. Reliability Requirements
Data centers operate around the clock.
Any failure involving cooling systems, fluid leaks, electrical connections, or infrastructure components can result in:
- Costly downtime
- Equipment damage
- Lost productivity
- Reduced service availability
At rack densities above 100 kW, even a brief cooling-loop failure can force an emergency shutdown within minutes — a far narrower margin for error than legacy air-cooled environments allowed.
As a result, material selection has become a strategic engineering decision rather than a commodity purchasing exercise.
What Makes Engineered Polymers Better Than Metal for Data Center Components?
Engineered polymers offer a unique combination of performance characteristics that make them ideal for data center applications.
Compared with traditional metal components, advanced polymer materials often provide:
- Superior corrosion resistance
- Reduced weight
- Enhanced electrical insulation
- Chemical compatibility
- Design flexibility
- Lower maintenance requirements
When properly selected, polymer components can improve both operational efficiency and equipment longevity.
Why Is Liquid Cooling the Fastest-Growing Data Center Technology?
Liquid cooling is rapidly becoming the preferred solution for high-density computing environments.
Unlike air, liquids transfer heat far more efficiently, enabling operators to cool increasingly powerful processors without expanding facility footprints. Recent industry surveys suggest fewer than half of data centers still rely on air cooling alone, with the remainder running liquid or hybrid systems — and that share is expected to keep shifting toward liquid cooling as AI rack densities climb.
The success of these systems depends heavily on fluid handling components.
Critical components include:
- Tubing
- Pipe systems
- Cooling manifolds
- Heat exchangers
- Seals and gaskets
- Quick-connect assemblies
These components must withstand continuous exposure to cooling fluids while maintaining dimensional stability and leak-free performance.
Flexible tubing is often used inside equipment and rack-level cooling assemblies, while rigid thermoplastic piping forms the backbone of many facility-wide cooling networks. PVC and CPVC are commonly used for chilled water, condenser water, and utility piping, while PVDF and PFA are specified where higher purity, enhanced chemical resistance, or specialty coolant compatibility is required.

What Other Thermal Management Components Do Data Centers Need Beyond Cooling Loops?
Thermal management extends far beyond moving coolant through a system.
Data centers require integrated approaches that include:
- Heat exchangers
- Thermal isolation components
- Fluid containment systems
- Cable protection systems
- Environmental controls
Advanced polymer materials help engineers manage heat while reducing contamination risks and maintenance requirements.
What Materials Are Used for Data Center Cable Management?
Data center cable management systems use engineered thermoplastics — primarily PC/ABS blends and reinforced polymer profiles — for raceways, routing channels, and support structures, combined with heat shrink tubing at the wire and connector level for insulation, identification, and environmental sealing. Pexco extrudes custom cable raceway profiles up to 30 inches wide and manufactures Insultab® heat shrink tubing to UL 224 VW-1 specifications.
Effective cable management solutions help:
- Improve airflow
- Reduce installation complexity
- Simplify maintenance
- Protect sensitive infrastructure
- Support future expansion
Wide-format extruded raceways address the routing demands of high-density fiber and copper environments that off-the-shelf components cannot. Pexco’s extrusion capability extends to 30-inch-wide profiles — a dimensional range that accommodates high-count fiber trunk runs, multi-tier copper routing, and integrated airflow channels in a single extruded cross-section. Custom raceway profiles can be designed to fit specific rack footprints, cabinet configurations, and hot aisle/cold aisle airflow management requirements, eliminating the stacking of multiple narrower channels and the associated installation complexity.
Insultab® heat shrink tubing from Pexco provides protection at the individual wire and connector level. In high-density data center environments, Insultab® serves four distinct functions: electrical insulation at terminations, color-coded circuit identification across high cable-count installations, abrasion protection at cable entry points and bend radii, and environmental sealing around connectors exposed to humidity or cleaning agents. Insultab® is available in polyolefin, PVC, and specialty fluoropolymer constructions, with ratings available to UL 224 VW-1 and other applicable standards.

Frequently Asked Questions
What is the best material for data center liquid cooling tubing?
PFA and PTFE are generally the top choices for liquid cooling tubing because of their broad chemical compatibility, low extractables, and continuous-use temperatures up to 500°F (260°C). FEP is a common alternative where flexibility and transparency matter more than peak temperature rating.
Is PFA or PTFE better for direct-to-chip cooling loops?
Both perform well. PFA is melt-processable, which makes it easier to form into precision tubing, fittings, and manifold components with smooth, low-particulate internal surfaces — an advantage in high-purity coolant loops. PTFE is not melt-processable but offers a slightly broader temperature range and is often used for static seals and gaskets within the same system.
What temperature can PFA tubing withstand in data center cooling systems?
PFA is typically rated for continuous use up to 500°F (260°C), well above the operating range of any coolant used in standard direct-to-chip or immersion cooling applications.
What seal materials are used in liquid-cooled data center racks?
Silicone and EPDM are the most common choices for general environmental sealing, while TPV and TPE are used where manufacturing flexibility matters. Fluoropolymer-based seals are specified for components in direct contact with aggressive or specialty coolants.
What compliance standards apply to data center fluid handling components?
Common standards include UL 94 V-0, UL 224 VW-1, SEMI F57, SEMI C90, and relevant ASTM material standards, depending on the application and coolant type.
What is the difference between PFA and FEP for data center applications?
PFA offers a higher continuous-use temperature (up to 500°F/260°C versus roughly 400°F/205°C for FEP) and better mechanical properties at elevated temperatures. FEP is more flexible and more transparent, which makes it useful for monitoring lines and flexible routing where visual inspection or bend radius matters more than peak temperature.
Why is air cooling no longer sufficient for AI data centers?
Traditional air cooling was designed for racks drawing roughly 6 to 15 kW. AI training racks now routinely exceed 30 to 40 kW, and some of the latest GPU platforms reach 120 kW or more in a single rack — densities that air alone cannot remove efficiently, which is why liquid cooling has become standard for AI infrastructure.
What materials are used for data center cable management?
PC/ABS and reinforced engineered thermoplastics are widely used for cable raceways, routing systems, and support structures because they combine impact resistance, dimensional stability, and compliance with flame-rating standards like UL 94 V-0.
What piping materials are used in modern data centers?
Modern data centers commonly use PVC, CPVC, PVDF, and PFA piping systems in addition to flexible fluoropolymer tubing. PVC and CPVC are often specified for chilled water and utility fluid distribution, while PVDF and PFA are selected for high-purity, chemically aggressive, or specialty coolant applications requiring enhanced performance and durability.
