Carbon solution
VINATech developed the original technology involving CNF (Carbon Nano Fiber) through independent research projects, in 2002. Subsequent development includes different carbon solutions including activating carbons, controlling the shape, composite and metal impregnated activation.
The application range of VINATech’s carbon solutions includes CNF, catalyst support for fuel cells, MEA (Membrane Electrode Assembly), and electrode and filter materials.
In particular, we lead the world in production of catalyst support, catalyst for fuel cell and MEA.
VINATech has been committed to pursuing research in the area of carbon materials and development of nano-composite technologies. We have developed efficient solutions for fuel cells and deodorizing filter.

Features of VINATech’s CNF
CNF(Carbon Nano Fiber) is a fiber-type carbon which has a strong crystalline property as well as nano-size fiber stems (5 – 350nm). This product comes in Platelet type where the graphene layers are arranged vertical to the direction of fibers. The Herring bone type involves lamination with a specific inclination. The Tubular type fiber is generated in parallel with the direction of other fibers. VINATech develops many different CNF products featuring a wide range of fibers stems, crystalline properties and structures structures through our processes for controlling the catalyst and response gas production conditions.

VINATech’s carbon controlling technology
VINATech has a shape controlling technology that boosts the crystalline property through a physical process applied to the CNF surface and by high-temp thermal processing; the process changes the surface property by rearranging the edges. We also have a complex solution which improves the conductivity of electricity, radiation properties, dispensability, and specific surface area by combining the strengths of each component material.
VINATech’s CNF is characterized by its excellent corrosion resistance developed through edge arrangement, dispensability
secured by modification of surface properties, and great electricity conductivity and radiation effects ensured by complexation.
We have secured CNF fuel materials and can produce any CNF products with properties such as surface adhesion, distance between layers, and ion’s interposing between layers optimized to the customer’s application requirements.

VINATECH
We will respond to you with
a customer-oriented attitude. We believe that we exist because you are there.
I personally began to open my eyes to the history of the world as I cut my wisdom teeth.
I guess that history itself can possibly commit faults and crimes just like human beings.
I am interested in how to cure the scars of wars and issues with Koreans abroad who suffer from the aftereffects.
I hope I can contribute a little to improving these people’s living standards,with an atoning attitude.
I believe this hope will be realized naturally as our overseas business expands.
We started as an electronic components trading company specializing in Tantalum Capacitors and, later in 2004, we expanded our business
to manufacturing Super Capacitors, an eco-friendly energy storage device,that I had longed for.
Based on our technical capacities built so far, we are committed to developing new products and technologies to be the world’s best quality and service provider. We promise to relentlessly follow the VINA spirit of ‘we exist because you are there’.
We will accomplish the VINA mission of ‘We provide eco-friendly products and contribute to the building of a harmonious society through the happiness of our members.’ Towards this, we will strive to realize our goal to become the leading company in relevant industries and create more valuable jobs.
Thank you for your sincere support for us and my best wishes to all your future endeavors.
VINATech CEO Sung, Do Kyong
