Pour point depressant msds pdf

While the Pour Point represents a rapid cooling, in reality the weather changes often slowly and so does the temperature. A history of broken engines and transmissions lead the industry to look not only at Pour Point, but at tests with a slow cooling procedure: MRV-TP1 for engine oils and Brookfield for transmission fluids. We support you with our experience and our laboratory to select the right PPD for your formulations. S ince base oils are not enough to perform the task expected from a lubricant, additives are used to improve the properties of the oil, and to avoid undesirable outcomes.

One of the most important additivies in this scope is Pour Point Depressant. This additive consist of high molecular weight methacrylate polymer and wax-containing components. It allows the oil to continue to flow at very low temperatures, prevents wax crystallization in the oil, and depresses the pour point.

There are two points to pay attention when using this additive in order to get optimum performance. The first one is to choose the right product considering the base oil and other additives used , and the second is to determine the amount of usage correctly. This material may cause adverse reaction if not used properly. Group I base oils are solvent-refined base oils with a viscosity index range of 80 to They have long been the cheapest base oils on the market but have shown considerable While environmental concerns are rising all around the world, lubrication in environmentally sensitive areas is an important issue that needs special attention.

NYCO Technical and Establishing an iron and steel factory require very high investment Colin Morton Dr. Ewan Delbridge Since no unified lubricant solution exists to encompass the changing requirements, only the nimblest manufacturers who can adapt quickly to Energy efficiency is one of the most important topics of this era. Holger Pletsch from Evonik Oil Additives, a leading German company which is an expert in the field of Total Lubricants introduced two new product series for electric vehicles whose importance and use are increasing day by day.

The company aims to meet the expectations of Greases are paste-like lubricants that are generally a yield of the reaction between base oils and metal hydroxides with acids and have consistencies ranging from Emergence and development of PPDs Prior to the s, the options for dealing with cold flow problems were very limited. Chemical structure of PPDs Even after 75 years, polyalkyl methacrylates, the first of the polymeric pour point depressants, continue to beviewed as the best chemistry available today, with a worldwide market share that far outstrips alternatives.

PPD selection and treat rate When new pour point depressants are designed or existing ones are used, it is important to recognize that these additives are themselves waxy materials. Factors that affect PPD selection and treat rate: Base stock Other waxy components Detergents and friction modifiers Viscosity modifiers Test methods required by different specifications Low-temperature performance reversion Aged-oil pumpability requirements PPD selection guide The screening of pour point depressants is best conducted on lubricants that are fully formulated but lacking pour point depressants.

Lubrication in environmentally sensitive areas: Making the right choice with esters While environmental concerns are rising all around the world, lubrication in environmentally sensitive areas is an important issue that needs special attention. How the PCL market is adapting to rapidly changing environmental conditions Dr.

Due to economic reasons, most refineries tend to use crude oils from a variety of sources. Depending on the origin of the crude and the conversion capabilities of the refinery that processed them, these fuels can differ significantly in their characteristics.

Examples are wax and asphaltene content as well as API gravity. All of these have a significant impact on the physical properties and cold temperature behavior of the fuel. Cooling down a sample of crude or residual fuel causes the formation of wax crystals, which in turn causes the oil to gel. Pour point is the lowest temperature at which a fluid is can be pumped before solidifying.

WAT is defined as the temperature at which the first wax crystals begin to form in heavy fuel oils and crudes. Linear paraffins can form needle- or plate-like crystals which can agglomerate and create a three dimensional network solidifying the fuel. Pour Point Depressants act as a wax crystal modifier. Modification is achieved by nucleation, co-crystallization and anti-agglomeration, which results in reduction of the size and shape of wax crystals.

Wax-crystals are not inhibited but modified in a way that they do not precipitate. The performance of a Pour Point Depressant does not only depend on the concentration and distribution of linear n-paraffins, but is also influenced by Asphaltenes and other components.

Recommendations are available on request depending on your specific crude challenges or after individual testwork in one of our laboratories. Most Pour Point Depressants are solid or waxy at room temperature and have to be warmed up before used. The time effort and complexity to use a PPD increases. It is difficult to use heatable systems in special areas, like EX-zones or on board. Fluid PPDs at ambient temperature can solve the problem. Other system you can get on request.

These include - but are not limited to - S. Based on the data received from these analyses, Clariant will select and recommend the best performing PPD for your needs.
