1. BASIC PRODUCTS

Basic products include the products of

Ethylene Plant (ethylene C₂H₄ and by-products propylene C₃H₆, C-4 fraction, pyrolysis gasoline, pyrolysis oil).

Chloralkali electrolysis Plant (sodium hydroxide NaOH, sodium hypochlorite NaOCl, hydrochloric acid HCl) and

Styrene-Butadiene-Rubber Plant (methyl-tertiary butyl ether- MTBE, 1-3 butadiene).

In HIP-Petrohemija ethylene with by-products is got by steam cracking of low octane virgin naphtha. In this process  the hydrocarbon compounds having higher molecular mass are converted into smaller compounds with double binding between carbon atoms.

Ethylene produced in HIP-Petrohemija can be used immediately for production of polymers - it has „polymer grade“ ethylene content of min. 99.9 %vol.

The produced propylene is of „chemical grade“ purity and has typical propylene content  of  92-94 % vol.

The products of Chloralkali Electrolysis Plant are made by electrolysis of industrial salt. These are the classical products of chemical industry, which are usable as raw material or auxiliary agent in various industrial fields, from production of chemicals, paper, glass to treatment of water, metal, textile.

Methyl-tertiary butyl ether (MTBE) is well known additive for unleaded motor gasolines. By adding MTBE there is increased octane number of gasoline and improved motor operating, Also, increased oxygen content enables better combustion of fuel. MTBE is got by reaction of isobutane and methanol. For getting isobutane there is used residue of C-4 fraction from which there is extracted 1,3-butadiene, by which there is utilized potential of Styrene-Butadiene-Rubber Plant to a great extent.

2. POLYMERS

Polyethylenes are macromolecules-polymers which are made by polymerization of ethylene.The polymerization conditions (mostly pressure) determine properties – polyethylene type and its later processing and usage.By ethylene polymerization at high pressure (1500 – 3000 bar) with presence of free radicals low density polyethylene is made; by polimerization at low pressure (abt. 42 bar) with catalyst high density polyethylene is made. For the reason of its properties, easy processing and great possibilities for usage, among all polymers polyethylenes are  used the most.They are especially dominant in the section of packing, because the modern processing, packing, transport and protecting of a product cannot be immagined without strong, resistant, impermeable and light packing material, which protects the product and reduces costs of transportation and storage and  gives the possibility of printing.

Styrene-butadiene rubber got by emulsion polymerization (E-SBR) is one of the most used polymers, having in mind its multiple application, from making car tires to toys. E-SBR is compatible with natural rubber and can replace it completely, and compared to it, it has better processing, resistance to abrasion and aging. From the other side, E-SBR is compatible also with other types of synthetic rubber, which with good processing and absorption of additives enables usage of various formulations for different types of products.

The greatest quantities of E-SBR (abt. 70%) are used for making car and truck tires, but there are also series of products at which E-SBR is irreplaceable.These are conveyor and driving belts, pipes and hoses, packings, technical parts and products for different industries (mechanical, pharmaceutical), floor covering and doormats, rubber shoes and soles, cables insulation, adhesives, toys.

Designed capacities are:

	HIPLEX® ( high density polyethylene - HDPE ) 60,000 t/y HIPTEN® ( low density polyethylene - LDPE ) 45,000 t/y HIPREN® ( styrene butadiene rubber - SBR ) 40,000 t/y
