Helium is one of the most sought-after noble gases. Due to its inertness, low boiling point and superfluidity, helium is widely used in high-tech industries, such as the rocket and space, nuclear and electronic industries, as well as in metallurgy .
The quality of liquid helium complies with Russian TU and all international standarts, including those in the field of environmental safety.
Delivery terms: FOB helium HUB Vladivostok, Russia

The price of helium for export, the detaileld procedure, the size of the batch, are discussed with the end buyer or his official representative in the presence of a mandate from the buyer.
1) Graphene Characterization and Quality
a) Our graphenes quality is validated through Raman spectroscopy (e.g., G/D ratio of 4.57, 2D/G of 0.4), a widely accepted method for characterizing graphene layers and defects; suggests alignment with global scientific standards
b) Our product is classified as multilayer graphene (5-8 layers), termed "few-layer graphene" (FLG)
c) High graphene-to-graphite ratio (85% graphene, 15% graphite)
d) 98.2697% carbon purity, and minimal defects, positioning it as a high-quality, rare offering in the 5-8 layer category
e) Uniformity of particles
f) Thin nanoplatelets (5-8 nm thick, 0.1-0.8 m diameter)
g) Low bulk density (0.02 g/cm³)
2) Capacity
a) Currently, 50 tons per month from a 400 sqm facility with 8 employees
b) Ability to set up production in 40 days suggests potential to double capacity (e.g., to 100 tons/month) with an additional facility, assuming resources and demand
c) With our scalable method and rapid setup, we could feasibly reach 150-200 tons/month by adding 2-3 facilities, though this depends on investment and infrastructure
d) Influencing Factors: equipment scalability, staffing (minimal increase needed), and facility replication speed (40 days per site)
3) Suitable Applications for 5-8 Layer Graphene
a) Electronics: flexible displays, high-efficiency transistors, and semiconductors
b) Energy: batteries, fuel cells, solar cells
c) Composites: enhanced mechanical and electrical properties
d) Medicine: drug delivery, biosensors
e) Concrete
f) Automotive tires
g) Excels in high-performance electronics and energy storage due to record thermal conductivity and mechanical rigidity
4) Comparison to Other Grades
a) Our 5-8 layer FLG offers a balance of conductivity and strength, unlike single-layer (narrow use, lab-scale) or 10+ layer graphene (common, less valuable)
b) It is rarer and more versatile than 8-10 layer graphene (limited to 1 ton/month elsewhere)
c) Many other graphene products offer less graphene content, 20% vs our 85%
