Sodium formate: preparation and properties Sodium formate is a compound representing an organic salt of formic acid. The chemical formula of the substance is HCOONa. The aggregate state is a crystalline powder of white or gray color, a greenish tint is less often observed. The substance is odorless, characterized by a moisture content of 3%. Producing Sodium formate is formed as a by-product during the… Sodium Formate
Pour point depressants (anti-gel) are a complex of additives that combine copolymers and surfactants, aimed at improving engine performance in the winter. Antigels prevent waxing and thickening of the fuel when the temperature drops. Depressant additives protect metal components of the fuel system from corrosion and promote complete combustion of the fuel. Where and why should we use anti-gel? The chemical structure of the liver… Pour point depressants
ABS plastic – impact resistant thermoplastic material ABS polymer is obtained by polymerization of acrylonitrile butadiene and styrene. Among the useful technological characteristics of the material, strength, surface gloss, easy coloring in the desired color, hardness and electrical insulating properties stand out. The main disadvantage is low resistance to ultraviolet radiation. Production All constituents of acrylonitrile butadiene styrene are listed in the name of the… ABS
Polyisobutylene – elastic rubber: production and applications Polyisobutylene is a synthetic saturated polymer with a carbon chain structure. Production technology of polyisobutylene is a low-temperature copolymerization of isobutylene isoprene or another diolefin. There are two main synthesis methods that differ in the polymerization medium. In the first case, aliphatic hydrocarbons are used, the second technique is focused on alkyl chlorides. Polymerization in liquid ethylene Synthesis… PIB
Application of EPDM The abbreviation EPDM means ethylene propylene diene M-class rubber. The key advantage of the compounds, which ensures their widespread use, is the availability and low cost of precursors (ethylene and propylene monomers). Other important characteristics for application are listed below: ozone resistance; resistance to weathering; chemical and thermal stability; excellent dielectric properties; ability to keep color. The intensive use of ethylene-propylene copolymers… EPDM
Ethylene-propylene copolymers: influence on the viscosity index Olefin copolymers (the class covers ethylene, propylene, butylene, other unsaturated aromatic hydrocarbons) are extensively used as viscosity modifiers. Such additives are able to compensate for the dependence of the fluid lubrication on temperature. The viscosity of mineral oils is more temperature dependent than synthetic oils. The reason is the difference in the size of the molecules. The viscosity… EPM
Our magazine already described the unique operation on delivery of hydrocracking reactors batch for Tuapse Oil Refinery (OAO Rosneft). Today we are publishing new details of this transport operation which is a real milestone event for our country.
The invention and the lifting spreader bar design relates to crane construction. The pipe spreader beam widener comprises of first and second hooks connected with a beam. There is a coupler section connector or a swivel connector at every end. Each of crane spreader bars elements has a possibility of extending in a direction away from the center, with or without an angle between the two parts.

Is adding Transmission Fluid (TF) as a lead additive really effective?
The lead additive has become a common practice in the automotive industry. This is because it helps reduce friction between the metal surfaces and the lubricant. As a result, it reduces wear and tear on the parts.How to Apply Transmission Fluids in automatic transmission
What is additive friction modifier (AFM) and why should I care? Additive Friction Lubricant (AFL) is a chemical compound used as a friction modifier in gear oils. AFL reduces friction by creating a thin film of oil between two surfaces. AFMs are typically polymers or waxes that coat surfaces and form a protective layer over them. This helps prevent wear and tear, extending the life… Additive friction modifier in transmission
