POUR POINT DEPRESSANTS
Automotive lubricants today constitute the largest share amongst various lubricants formulated globally. These lubricants include engine, hydraulic and gear oils. About 95% of these lubricants are based on petroleum derived Base oils where the amount of Base oil in any formulation can vary from 75-90%. Considerable process improvements have been implemented to raise the quality of Base oils. These new processes have, in many cases, significantly modified the nature and contents of the paraffins found in these base oils making them more difficult to pour depress. These Base oils are broadly classified as Group I, II and III depending on the level of sulfur and paraffin / saturates.
Automotive Lubricants need to flow freely throughout the engine & other critical components to lubricate and protect them. As temperatures drops, the paraffin present in the Base oils begins to precipitate and agglomerate forming interlocking wax crystals making the oil very thick and difficult to flow. Thus, below the pour point, the lubricant will not have the ability to flow freely and would be responsible for these critical components to grind together causing serious damage.
Pour point depressants are used to modify and control wax crystallization phenomenon in petroleum Base oils. These additives are used to maintain fluidity of lubricants at lower temperatures and thus help expand their operating temperature range. These additives are also known as Flow improvers, Antifreeze additives, wax modifiers etc.
CRISTOL Pour Point additives are developed to keep your automotive lubricants flowing in the cold. They provide the versatility you need to effectively treat the wide range of new generation Base oils and permits product rationalization. They are recommended for use in a wide variety of lubricants including engine, hydraulic and gear oils.
