Siman Ltd. Is able to offer to its customers a diverse range of industrial chemicals that finds an application in: leather, textile and rubber industry, heat treatments of metals and others.
The products that we offer are:
Chromium trioxide (Chromic acid) - it is a strong acid and oxidizing substance. When neutralized with alkali forms dichromate or chromium compounds. The low sodium content is appropriate for processes of catalyst and other special application.
Chromic oxide (Dichromium trioxide), metallurgical is an inorganic compound. Light green crystalline powder, soluble in water and organic solvents and used in metallurgy as a pigment.
Potassium nitrate, technical grade is a crystalline powder with white colour, sometimes slightly yellowish-green. It is easy soluble in water. Used in many sectors in industry and agriculture: as a component of some types of powders and pyrotechnics mixtures; in the glass industry for decolorization and clarification of crystal glass to reinforce the glass; in the manufacture of enamels, thermal salts; in the metallurgy for hardening/tempering of metals; as an undiluted valuable fertilizer containing two nutrients.
Sodium nitrate is a white solid substance which is very soluble in water. It is used in the chemical glass, metallurgical and other industry; in the manufacturing of pipes, as well as fertilizer.
Sodium fluoride. Sodium fluoride is white crystalline solid. Used in the brewing industry and in the distillation of the spirits; as a substitute of HF in stainless steel pickling; in the manufacture of casein glue and other adhesives; in glass polishing; in fluoridation of drinking water; enamels and ceramics, toothpastes; salts
Caustic soda (Sodium hydroxide). Strong base, very soluble in water, alcohol, glycerin and absorbs carbon dioxide and moisture from the air. The main use of Sodium hydroxide is as a chemical and in the manufacturing of other chemicals. It is used also in textile industry as well as in making paper and cellulose.
Siman Ltd. Has extensive experience in metal finishing. Galvanotechnics is an area of applied electrochemistry that deals with the processes of deposition of metal coating on the surface of the metal and non-metal products by leakage of electrical current through a solution of their salts. Our product and accessories are guaranteed quality and are used in all types of plating operations such as chrome, nickel, cadmium, silver and copper coating and etc.
The range of our products includes:
Chromium trioxide. Chromic acid is a strong acid and oxidizing agent. When neutralized with alkalis, chromic acid forms dichromate or chromate compounds. The low sodium content is suitable for use in catalysts and other special applications.;
Nickel chloride. Nickel chloride is soluble in water, while not so soluble in alcohol and organic solvents. It is an important element for galvanic baths and in the form of anhydrous, nickel chloride is used in anti-gas masks as ammonia absorbent.
Nickel sulphate. Nickel sulphate is a blue or emerald green crystal and is very soluble in water and ethyl alcohol. Nickel sulphate is mainly used in nickel-plating and in the chemical industry to produce catalysts for hydrogenation of greases.
Potassium sulphate
Copper sulphate
Anodes (nickel, zinc, copper and etc.)
Siman Ltd. has the possibility to offer to its customers ammonium, phosphorus as well as combined fertilizers. We have built up tight and close relationships with producers and traders in Bulgaria, Germany, Russia, Ukraine, India, China, Brazil and many other countries. This gives the opportunity to offer various modes of fertilizer’s deliveries - from container lots to vessel lots, in PP bags or in bulk, over the seas or inland - Siman Ltd. Always finds the right decision.
Bellow are listed the fertilizers that we can supply. You are kindly requested to get in touch with us if you have any questions or concerns and/or need an offer./
Monoammonium phosphate (MAP). Monoammonium phosphate is a high concentrated nitrogen-phosphorus fertilizer in white granule. It is suitable for all kind of soils and crops. It is brought in with main cultivation of soil or pre-seeding. Amorphous is a suitable means for increase of yield and quality of produce.
Total Content of Nitrogen: 11% ± 0.5%, P2O5 content: 52% ± 0.5%
Diammonium phosphate (DAP). Granulated universal highly concentrated nitrogen-phosphorus fertilizer. Value of nitrogen and phosphorus 18-46 increases the resistance of plants to adverse environmental factors (drought and frost), and also increases the resistance of plants to disease. High content of phosphorus contributes to the accumulation of sugar in the root crops and fruits.
Total Content of Nitrogen: 18% ± 0.5%
P2O5 content: 46% ± 0.5%
Triple superphosphate (TSP). The most important fraction of the phosphorous feed, which is indispensable for the high and quality crop yields, is present in the granulated triple super phosphate. This fertilizer is classified in the group of the water soluble, fast acting phosphates. Its super physical and chemical specification makes it universal and suitable for any soils and crops.
Water- and citrate- soluble P2O5: min. 45,5%
Water-soluble P2O5 max.: 43,0%
Urea, granulated. Urea is a white crystalline substance. Universal concentrated water-soluble nitrogen fertilizer is intended for use under all growing crops on all soil types. It contains 46% nitrogen. Content of Nitrogen: min. 46,2%
Complex fertilizers (NPK( 8:24:24)). Complex fertilizer contain the tree basic nutrient elements produced in different proportions according to the requirements of the specific group of crops, soil reserves, projected yield, market needs and other factors. Recommended mostly with autumn crops. Applicable with main cultivation or pre-seeding.
Ammonium nitrate. Ammonium nitrate is granulated product without foreign solids. Universal highly concentrated nitrogen fertilizer containing ammoniac and nitrate forms of nitrogen in equal ratios. Application of ammonium nitrate in small doses reduces the losses of nitric nitrogen due to leaching.
Nitrate and ammonium nitrogen N as dry matters, not less than: 34,4%
SIMAN LTD cooperates with an European producer of industrial waxes. Our partner is an independent blender and is therefore able to operate best in the raw and semi-finished wax markets, offering products which, besides being the best suited for all requirements, are price competitive. The final goal is the customer's success, to which we contribute with high value-added products.
Natural Waxes (Paraffin Waxes):-
Obtained from the light lubricating oil distillates and composed of around 90% straight-chain hydrocarbons (20 to 30 carbon atoms).
Animal (beeswax, lanolin, tallow)
Vegetable (carnauba, candelilla)
Fossil or mineral (ceresin, montan, ozokerite)
Petroleum (paraffin, microcrystalline, petrolatum)
Synthetic waxes (Microcrystalline waxes):-
Obtained through mixing heavy lubricant oil distillates and residual oils, these waxes have a loosely defined crystalline structure, a darker colour and generally have a higher melting point and viscosity than paraffin's.
Ethylenic polymers (polyethylene and polyol ether-esters)
Chlorinated naphtalenes
