Carbon Black
Carbon black (K- 354) is a generic term for an important family of products that is used principally for the reinforcement of rubber, as a black pigment and because of its electrically conductive properties. It is an extremely fluffy fine powder with a large surface area and is composed essentially of elemental carbon. Carbon black is one of the most stable chemical products. In general, it is the most widely used nanomaterial and its aggregate dimension ranges from tens to a few hundred nanometers (nm); it imparts special properties to composites of which it is a part.
Our Carbon Black is produced by the leading chemical plant manufacturers in Turkmenistan as is of the highest quality.

Crude Iodine
Iodine is a naturally occurring mineral that is commercially available as crystals or a tincture. It is the commercial form that is referred to as Crude Iodine.
Iodine Crystals are a metallic violet colour. They are used for a variety of commercial and medical purposes including the below:
- make chemicals, polymers, sanitation and cleaning compounds, pharmaceuticals, nylon fibres, dyes and ink, and photographic film
- to help crime scene investigators revealconcealed fingerprints on surfaces
- As a nutritional supplement in table salt
- In dietary supplements for livestock
- In the production of electric light bulbs
- For water purification and as a chemical in swimming pool sanitization
- As a antiseptic for humans, horses, and cattle after the crystals are made into iodine tincture
We supply Grade A Crude Iondine (I2) in Crystal form worldwide. These are contained in certified, individually sealed and lined, UN approved, 50kg plastic drums.
