PureGRAPH® 20 Graphene

PureGRAPH® 20 – Industrial Graphene for Advanced Concretes, Technical Mortars and Structural Composites

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.

THE PureGRAPH® 20 It is graphene in nanoplatelets with average size (D50) of 20 µm, specially developed for heavy engineering applications, civil construction, structural composites and high-performance resins.
This is one of the most internationally recognized degrees for its effectiveness in:

• mechanical reinforcement,
• increased durability,
• reduction of permeability,
• Significant improvement in structural integrity.

Independent tests on mortars and concretes show impressive results:

• +34% compressive strength,
• +27% tensile/flexural strength,
• reduction of microcracks,
• longer lifespan in harsh environments.,
• Potential reduction in cement use, contributing to lower CO₂ emissions.

If there is a grade in the PureGRAPH® line created for real engineering, and the PureGRAPH® 20.
