Tailor-made grades:
- Our plants have extensive customisation and finishing facilities to tailor-make to our customer’s specific requirements and applications.
Standard range:
- Designed based on our extensive understandings of the user industry domain, standard grades are available.

Hydrated Graphite Powder

A distinct advantage

Given the diversity of Flake Graphite test parameters and procedures, while we have adopted internationally approved best standards, we prefer to synergize our procedures and equipment with yours, in close coordination with your QA department. These could include using test sieves identical to customer source, adopting testing procedures from a customer's QA for production and pre-dispatch analysis for shipments meant for them, deeply understanding your critical needs and aligning to deliver it consistently.
