PureGRAPH® 70 Graphene

PureGRAPH® 70 – High-Dimensional Graphene Nanoplatelets for Maximum Reinforcement in Heavy Engineering

The line PureGRAPH® First Graphene represents a new generation of graphene nanoplatelets developed for demanding industrial applications. Produced by a proprietary single-step process, PureGRAPH® nanoplatelets combine Large lateral size, low defect level, and controlled surface functionalization., delivering superior performance with excellent batch-to-batch reproducibility.

Available in six rigorously controlled platelet sizes — 5, 7, 10, 20, 50 and 70 µm (D50) — PureGRAPH® allows you to select the ideal graphene according to the desired property, whether electrical and thermal conductivity, mechanical reinforcement, barrier, anti-corrosion or durability.

Graphene PureGRAPH® 70 It is the highest grade in the PureGRAPH® line, containing graphene nanoplatelets with average size close to 70 µm, designed specifically for applications requiring extreme rigidity, extended durability, and maximum reinforcement in large industrial dies.
Its enlarged size provides greater mechanical anchorage within the matrix, offering significantly superior structural gain in:

• Industrial concretes;
• Heavy precast elements;
• Structural blocks;
• Thick epoxy parts;
• Composites used in extreme load applications;
• Infrastructure and advanced civil engineering;
• Coatings for electromagnetic shielding;
• Antistatic and dissipative (ESD) materials.

THE PureGRAPH® 70 It is ideal for projects where structural flaws are addressed with the utmost rigor.

Overview of PureGRAPH® 70 Graphene

• Type: Graphene nanoplatelets (graphene nanoplatelets – GNPs);
• Average platelet size (estimated): ~70 µm
• Apparent density: Greater than 50/20 grade (robust platelets)
• Structure: Multilayered, high crystallinity
• Defect level: Low (PureGRAPH® standard)
• Main applications: Structural concrete, solid composites, thick epoxy, heavy engineering

This grade is designed for extreme load transfer, where larger platelets dramatically increase mechanical reinforcement.

Why choose PureGRAPH® 70 Graphene?

✔️Maximum load transfer
Larger platelets offer greater interfacial contact and significantly superior mechanical reinforcement.
✔️Extreme structural reinforcement
Ideal for dense matrices where strength, toughness, and stability are essential.
✔️Deep reduction of microcracks
The size of the platelets improves cohesion and reduces critical points in resins or concrete.
✔️Longer structural lifespan
Perfect for harsh environments, high abrasion, heavy loads, or severe cycles.
✔️Effective booster with low dosages
Even a difference of 0.02%–0.1% can completely transform performance.

Direct benefits in applications

How to use PureGRAPH® 70

PureGRAPH® 70 should preferably be dispersed in higher viscosity systems, such as cementitious pastes, dense epoxies or thermosetting composites.
Recommended dosages start at 0.02% to 0.08% for concrete and 0.1% to 0.8% for structural epoxies.
In solid composites, performance increases almost linearly with dosage.
