October 30, 2025

Graphene has moved from being a laboratory promise to becoming a tangible tool for solving real-world challenges in technology, medicine, energy, and manufacturing. If you work in industries where innovation and performance matter, understanding what graphene is, what it’s used for, and how it can be applied can help you make a qualitative leap in your projects.

This article offers a clear, professional, and practical guide to graphene — its properties, current applications, and how it can benefit your field of work.

What Is Graphene and Why Should You Pay Attention to It?

Graphene is a material made up of a single layer of carbon atoms arranged in a hexagonal lattice, similar to a honeycomb. It’s so thin that it’s considered two-dimensional, yet so strong that it can be harder than steel.

Although it was first isolated in 2004, graphene quickly became a cornerstone for advanced technologies. From flexible electronics to new medical treatments, graphene is reshaping entire industries.

If you need materials that combine high mechanical, thermal, electrical, and chemical performance with low weight and thickness, this material deserves your attention.

What Is Graphene Used for in Professional Environments?

The right question isn’t just what graphene is for, but what problems it can help you solve. Here are a few areas where graphene truly makes a difference:

Electronic engineering: enhances the performance of sensors, transistors, antennas, and flexible boards.
Energy industry: improves the capacity and lifespan of batteries, solar panels, and supercapacitors.
Aerospace and automotive: reinforces composites to reduce weight without compromising strength.
Construction: added to cements or coatings to improve durability and resistance to water or fire.
Technical textiles: enables fabrics with conductive, thermal, or antimicrobial properties.
Advanced medicine: supports biomedical sensors, drug delivery systems, and smart prosthetics.

If you work in any of these fields, graphene has likely already entered your technical conversations.

Properties That Make Graphene So Valuable

The reason so many companies and research centers are investing in graphene lies in its extraordinary properties. This isn’t scientific hype — these traits directly enhance product and process performance:

Ultra-strong: up to 200 times stronger than steel, with a thickness of one atom.
High electrical conductivity: even better than copper — ideal for sensors and electronics.
Excellent thermal conductivity: helps dissipate heat in demanding devices.
Extremely lightweight: improves weight-to-performance ratios.
Impermeable: acts as a barrier against gases and liquids.
Flexible and elastic: doesn’t break when bent.
Biocompatible: can integrate into medical devices safely.

These features make graphene a perfect choice for anyone looking to reduce weight, boost efficiency, or add smart functionality to their products.

Main Applications of Graphene

Although research continues, there are already many commercial and pre-commercial applications for graphene:

Flexible Electronics
Ideal for foldable displays, body-adaptive sensors, and more accurate wearables. Graphene enables thinner, more responsive devices.
Energy Storage
Graphene-enhanced batteries charge faster, last longer, and operate more safely — making them prime candidates for electric vehicles and renewable energy systems.
Industrial Reinforcement
Used in resins, plastics, and cement to improve mechanical strength, waterproofing, and thermal resistance.
Smart Coatings
Paints and varnishes with graphene can be anticorrosive, antistatic, flame-retardant, or even self-cleaning — ideal for industrial environments.

Graphene in Medicine: From the Lab to the Operating Room

The use of graphene in medicine is advancing rapidly. If you’re in the biomedical, research, or healthcare sector, these applications will sound promising:

Ultrasensitive biosensors: for fast and precise diagnostics.
Smart implants: prosthetics and pacemakers with greater durability and less rejection.
Neural electrodes: for brain stimulation or signal detection.
Targeted drug delivery: graphene can encapsulate and transport medicine directly to affected areas.

Thanks to its biocompatibility and precision, graphene is becoming a key player in personalized medicine and medical technology innovation.

Pultrusion profiles: innovation transforming the industry.

What is Pultrusion and Why It’s Revolutionizing Profile Manufacturing

Pultrusion is an industrial manufacturing technique increasingly used in sectors that demand strong, durable, and lightweight materials. In essence, it’s a continuous process that creates reinforced profiles — most often using fiberglass — by pulling fibers through a heated mold.

But what exactly is pultrusion? Imagine a system where fibers such as glass or carbon are impregnated with resin and continuously drawn through a mold that shapes and solidifies them. This is how pultruded profiles are made — valued for their stability, strength, and adaptability.

How the Pultrusion Process Works

The pultrusion process is simpler than it seems, yet highly technical. It begins with continuous fibers fed from spools. These fibers pass through a liquid resin bath, usually polyester or epoxy, which coats them completely.

Once impregnated, the fibers enter a heated mold that defines the final profile shape. The resin hardens with the heat, and the finished product is continuously pulled out and cut to the required length. Controlling temperature, speed, and pulling force is key to maintaining precise tolerances and consistent quality.

This process allows for the production of everything from thin rods to complex structural profiles — all with exceptional mechanical strength.

Advantages That Make Pultruded Profiles Stand Out

Compared to traditional materials such as steel, aluminum, or even wood, pultruded profiles offer clear advantages:

Much lighter while maintaining stiffness and strength.
Corrosion- and rust-resistant, ideal for harsh environments.
Non-conductive, making them safe for electrical applications.
Low maintenance and long-lasting.
Dimensionally stable, even under extreme weather conditions.

Thanks to these properties, pultruded profiles are widely used in outdoor structures exposed to sunlight, humidity, or chemicals — environments where other materials would fail.

Fiberglass Pultrusion: The Perfect Balance of Strength and Cost

When we talk about pultrusion, fiberglass is the most common reinforcement choice. Why? Because it offers the ideal balance between performance and cost. It’s strong, affordable, non-conductive, and suitable for a wide range of applications.

In sectors such as construction, agriculture, chemical industry, and marine engineering, fiberglass profiles have become a standard solution. Common uses include:

Railings and outdoor structures
Industrial grating (tramex)
Technical ladders
Machinery components
Agricultural stakes

Manufacturers like Polymec, based in Spain, operate under strict European standards such as UNE-EN 13706, ensuring structural quality in every profile produced.

Types of Pultrusion Profiles Available

One of pultrusion’s great strengths is its versatility. Standard shapes can be produced, but custom designs are also possible for specific applications. The most common include:

Rods (smooth, ribbed, round, or square)
Tubes (round, square, rectangular, telescopic)
Flat bars (plain or special geometry)
Angles, U-profiles, I-beams, dog bones, corner pieces
Gratings (tramex)
Special profiles: steps, manhole covers, skirting boards, tool components

In Polymec’s catalog, there are versions made with fiberglass, carbon fiber, or even graphene additives, offering enhanced properties such as thermal conductivity or chemical resistance.

Standards in Pultruded Profiles: Safety and Quality Assurance

Producing pultruded profiles is not just a technical process — it must also comply with international standards to ensure safety and performance.

In Europe, the key reference is EN 13706, which classifies profiles into two categories: E17 (standard) and E23 (high quality). Polymec manufactures under the latter, meeting stricter requirements for stiffness, strength, and dimensional tolerances.

These profiles are also tested under EN ISO 527 and EN ISO 14125 standards to evaluate their behavior under tension, bending, shear, and other mechanical loads.

Pultrusion and the Future: Growing Applications

The potential of pultruded profiles extends far beyond current uses. Their future is bright — especially in industries seeking sustainable, durable, and long-lasting materials. Emerging applications include:

Supports for solar panels and wind turbines
Railway and marine infrastructure
Components for smart urban furniture
Modular construction systems
Lightweight parts for automotive and electric transport

Thanks to specialized companies like Polymec, which not only manufacture but also advise and customize solutions, pultrusion is positioning itself as a key technology in the shift toward a more efficient and sustainable industrial future.

The first products made with graphene composites are being introduced.

The first products made with graphene composites were presented at the JEC World Composites trade fair held in Paris this March. These are pultruded profiles with graphene that, thanks to this nanomaterial, improve the mechanical properties of conventional pultrusion profiles. They maintain the same weight but significantly increase strength — even surpassing that of steel, something unthinkable until the arrival of graphene.
At Polymec, we manufacture pultrusion profiles with graphene, marketed under the name CompoSmart, in Murcia.

The most innovative nanomaterial of recent times is set to play a key role in the future of composite materials. Graphene’s mechanical properties make it an ideal material to incorporate into composites to enhance their strength and durability.

At the JEC World in Paris, a section of a boat similar to the Graphenano One could also be seen — a vessel unveiled last October in Alicante to great anticipation, as it is the first boat built entirely from graphene-enhanced composite. Among its advantages: greater strength, lighter weight, higher speed, fuel savings, reduced material use during production, and lower environmental impact.

Graphenano Composites works with Gazechim for the supply of resins, which are enhanced with graphene in Graphenano’s laboratories.

Six-month RECOTRANS meeting.

On March 9th, the second meeting of the RECOTRANS Project consortium was held, coordinated by AIMPLAS, in which we are partners.
The goal of this project is to develop a new manufacturing system to produce multi-material composites suitable for the transport industry, achieving lightweight, high-quality materials.

The next steps will include defining and designing the three demonstrators, finalizing the formulation of the materials, setting the parameters for the laser technology, and integrating microwave technology into the resin transfer molding and pultrusion lines.
