Gerdau Graphene

Haydale has announced a new contract agreement with Gerdau Graphene, which focuses on the development, industrialization and commercialization of chemical additives, mineral additions and masterbatches with carbon-based nanomaterials, such as graphene.

This collaboration between Haydale and Gerdau Graphene will facilitate the development of graphene infused product lines and synergy between the advanced materials.

Gerdau Graphene has launched “NanoCONS,” a new line of graphene admixture solutions designed for the construction industry, meant to enable concrete producers to leverage the physical properties of graphene to improve the mechanical performance of their concrete products. 

The integration of NanoCONS into cementitious materials may also reduce carbon emissions associated with concrete production: according to recent research on graphene-enhanced concrete, reducing cement content can lower concrete manufacturing-related emissions by up to 20%. NanoCONS can help reduce cement consumption without any loss of concrete performance, thereby contributing to more sustainable concrete production.

Gerdau Graphene has announced the availability of NanoCORR Shield, the newest product from its G2D NanoCORR line of anti-corrosion paints and coatings additives. Developed with Gerdau Graphene's exclusive G2D technology, NanoCORR Shield is a graphene-enhanced chemical additive designed to increase the corrosion resistance of solvent-based paints and coatings. NanoCORR Shield has demonstrated a 30-70% increase in corrosion resistance when subjected to salt spray testing.

The addition of a small amount of specially-developed graphene into paints and coatings allows for an increase in the barrier effect against corrosive elements such as water, oxygen, and chlorides. In addition, NanoCORR reduces paint consumption by reducing the nominal thickness of the coating while maintaining the paint or coatings' other characteristics and performance properties.

Black Swan Graphene has announced the commercialization of a new product, the GraphCore family of graphene nanoplatelets products. These products, now in full production volume, are tailored to meet a diverse range of needs within the polymer industry, offering various forms including powders and polymer-ready masterbatches.

According the the Company, in addition to double-digit tensile property improvements with less than 1.0% loading, performance enhancements seen at global customer industrial trials include:

* 25% weight reduction with 1.5% loading in TPU;
* More than 20% impact resistance improvement in PP at 0.2% loading; and
* More than 40% improvement in barrier properties in PLA at 1.0% loading.

Gerdau Graphene has announced that Brazil has adopted an internationally-recognized industry standard for graphene. The Brazilian standard, published by Brazil’s National Standards Forum (ABNT), is identical to an existing international graphene standard that was developed in collaboration with more than 30 countries, including Brazil, under ISO/TC 229 – Nanotechnologies. The standard aims to characterize the different products that make up the class of materials named graphene, thus contributing to the development of new technologies.

In addition, Gerdau Graphene hosted an international consortium of nanotechnology researchers and industry leaders from April 8-12, 2024, in São Paulo, Brazil. The ISO/TC 229 – Nanotechnologies working groups covered topics related to terminology and nomenclature; measurement and characterization; health, safety, and environmental aspects of nanotechnologies; material specifications; products and applications; and more.

Gerdau Graphene, in collaboration with Gerdau (its parent company and a major Brazilian steel manufacturer), has unveiled graphene-infused packaging for Gerdau’s nail product line manufactured at three facilities in Brazil. Utilizing the new packaging is expected to reduce Gerdau’s direct plastic consumption by around 25%, or more than 72 tons per year.

Produced with proprietary G2D technology, the new packaging incorporates 1% Poly-G PE-07GM, the company’s inaugural polymer masterbatch with graphene dispersed in polyolefins such as polyethylene (PE) and polypropylene (PP). Poly-G is suitable for the production of films, profiles, and sheets formed through the extrusion processes. The new thermoplastic products created using Poly-G PE-07GM are reportedly proven to be stronger and offer greater overall performance while costing less to manufacture and producing significantly less waste across the value chain. In addition, the products are lighter and longer-lasting, reducing total plastic waste by up to 40%.

Gerdau Graphene has announced that Packseven, one of Brazil’s largest flexible film makers, will be commercializing  what they define as 'the world's first graphene-enhanced stretch film'. It is expected to be made available for sale in Q3 2023.

The new ultra-thin film, developed using Gerdau Graphene’s specialized graphene additive technology, is said to be significantly thinner and more durable: initial testing revealed that the new films could pack 120% more material without breaking compared with comparable flexible films. More durable stretch films reduce consumption of the material per pallet and increase safety in packing and loading. 

Gerdau Graphene has launched two new additives specifically formulated for the paint and coatings industry: NanoDUR and NanoLAV. The new additives, produced with the company's proprietary G2D technology, utilize graphene nanoplatelets to deliver improved performance for water-based paints and coatings — without altering pH levels. The additives also reduce or eliminate the need for some traditional manufacturing inputs, additives, and processes, which can lower production costs while improving sustainability and reducing environmental impact.

"Until recently, it has been virtually impossible for coatings manufacturers to upgrade product performance, slash manufacturing costs, and improve sustainability at the same time — it simply couldn't be done. Now, the application of carbon nanomaterials, such as graphene, in commercially available additives has made this possible and will act as a game-changer for the industry," said Alexandre de Toledo Corrêa, CEO of Gerdau Graphene. "NanoDUR and NanoLAV represent the new performance, economic, and sustainability edge for coatings manufacturers, enabling them to leapfrog competitors across the value chain. These are the newest in our growing portfolio of graphene additives and we're excited to partner with industry leaders to develop even more novel, powerful applications for graphene."

Gerdau Graphene, a nanotechnology company focused on the production, development, and commercialization of graphene-enhanced materials for industrial applications, has announced that it has landed the first sales of its graphene-enhanced Poly-G PE-07GM polyethylene masterbatch. The additive is suitable for the production of films, profiles, and sheets formed through the extrusion processes. 

The new thermoplastic products created using Poly-G PE-07GM are said to be stronger and offer greater overall performance while costing less to manufacture and producing significantly less waste across the value chain. Poly-G PE-07GM was piloted in a series of industrial applications within Gerdau’s factories before
commercialization, including as a film for construction nail packaging. Gerdau found that by using the new, 25% thinner graphene-enhanced plastic film, far fewer nails perforated the packaging. As a result, Gerdau reported a 39% reduction in the volume of discarded damaged packaging and a 7% increase in
film productivity.

Gerdau Graphene has announced that it has created a new water-based graphene-enhanced architectural paint that is significantly more durable and resistant to abrasion than traditional paints. The new paint could be used on concrete, cement, metal, and asphalt, such as on sidewalks, bicycle lanes, garages, staircases, sports courts, and a wide array of commercial and industrial areas.

Its parent company, Gerdau, reportedly began applying the new paint to its factory floors in March, making it the world’s first large-scale use of a water-based graphene-enhanced architectural paint. The company is already selling its proprietary graphene additives as development prototypes to major paint producers in the Americas.
