General

Viscosity Index (VI) Improvers is a crucial component in the formulation of advanced lubricating oils offered, ensuring peak performance across a wide temperature range. These improvers are engineered to elevate the VI of engine oils, meaning they help the oil maintain optimal thickness (viscosity) in both searing heat and freezing conditions.

Incorporating VI Improvers into your lubrication regimen guarantees that your engines start effortlessly in cold climates while providing steadfast protection and reduced friction at high temperatures. This dual-action benefit results in enhanced fuel efficiency, decreased oil consumption, and prolonged critical engine components’ life.

Chempol’s range of VI Improvers results from cutting-edge research and innovation designed to meet and exceed the demands of modern engines that operate under extreme stress and varying conditions. Our products ensure that viscosity is maintained, performance is maximised, and engines run smoother for longer.

The sophisticated molecular design of these polymers guarantees a superior, stable lubricant that delivers consistent performance, whether you’re starting your engine in the frosty depths of winter or operating at the peak of summer heat.

With Chempol’s VI Improvers, customers can expect an unparalleled advantage — a lubricant that meets and exceeds the performance requirements of mineral and synthetic base oils. Our products ensure your machinery is protected; your operations are smooth, and your maintenance costs are reduced.

Invest in VI Improvers for your oils and experience the pinnacle of lubrication technology that keeps your engines running like clockwork in any weather, under any stress. It’s not just oil; it’s a promise of peak performance and reliability, with extra qualities of ashless additives.

VI Improvers are The Pinnacle of Modern Technology

Chempol’s Viscosity Index (VI) Improvers are revolutionizing the world of lubricants with their advanced polymer technology, enhancing the performance of oils by maintaining an optimal viscosity across a range of temperatures. These improvers leverage the principle that polymers expand more at higher temperatures, increasing the viscosity more significantly where it’s needed most.

The unique selling point of Chempol’s VI Improvers is their ability to adapt to temperature changes, ensuring engines perform consistently in varying climates. This results in a lubricant that protects against wear in extreme heat and ensures easy start-up in cold conditions. The polymers in Chempol’s VI Improvers are carefully selected for their interaction with oil molecules, providing a stable, high-quality product.

Chempol’s TBN booster additives and VI Improvers are backed by rigorous research and development, referencing foundational studies like those of Flory, and are designed to react optimally within the lubricant solution. Whether in ‘poor’ or ‘good’ solvents, our VI Improvers are formulated to prevent the collapse or overexpansion of polymer chains, maintaining the perfect equilibrium for your engine’s lubrication.

By choosing Chempol’s VI Improvers, you’re selecting a product that not only enhances the longevity and efficiency of your engines but also reflects a commitment to innovation and excellence in lubrication science. Make Chempol’s VI Improvers a part of your lubrication strategy and witness your machinery’s performance soar.

Finding out the science behind the VI improvers

Our advanced VI Improvers are crafted to provide your engine oils with the resilience needed to maintain consistency across temperatures. Tailored for diverse applications, these polymers ensure your engines deliver top-tier performance, whether braving the winter chill or enduring summer’s blaze.

Chempol’s VI Improvers stands out in the market with their unparalleled performance, ensuring that viscosity is not a liability but an asset for your engines. Besides that, our anti-rust additives perform outstandingly with VII. Our meticulously engineered products represent the pinnacle of lubrication technology, providing a trusted solution for maintaining engine efficiency and extending service life.

Chempol’s High-Quality Products

CHEMPOL P25 Ethylene – Propylene – Copolymer

Chempol P25, when blended at 10% with SN500 Base Oil, achieves a viscosity range of 1900 to 2000 cSt at 100°C and at an 11.5% concentration with SN150 Base Oil, it reaches 1800 to 1900cSt at the same temperature. This formulation is designed for crafting Liquid VI with SN150 Base Oil to improve low-temperature performance in Motor Oils, enhancing the viscosity index proportionate to the grade used. Dissolution requires 3-6 hours at 120°C. For safety, use dust masks and gloves, store polymers below 30°C, shield from sunlight, and are available in 25 kg packages.

CHEMPOL 5530 Viscosity Improver (Solid Form)

Chempol 5530 is a type of product added to motor oils and industrial lubricants to help them work well under different conditions. It’s made from a mix of chemicals known as Olefin Co-Polymer (OCP) and is specifically an Ethylene Propylene Co-Polymer. This product is solid and helps the oil keep its thickness even when it’s worked hard or under a lot of pressure. How much of this product is used in the oil depends on what the oil needs to do and how it needs to perform.

CHEMPOL 5550 Viscosity Improver (Bale Form)

Chempol 5550 is a Viscosity Improver, which is a solid product and is used to make various types of motor and industrial oils. It is made to work better across different temperatures ranging from cold to warm. It’s made from a synthetic material called Olefin Co-Polymer (OCP), specifically an Ethylene Propylene Co-Polymer. When mixed with other appropriate oils, it offers a medium level of resistance to thinning out under high pressure or mechanical action. The amount used can vary based on what the oil will be used for and how it needs to perform.

CHEMPOL P20 OCP Viscosity Index Improver

Chempol P20 OCP Viscosity Index Improver is a polymer that needs to be mixed into oil at high temperatures (130 degrees Celsius) and stirred vigorously for 3 to 4 hours until it fully dissolves. The amount you need to use varies from 4 to 10% based on how thick or thin you want the oil to be. It should also be matched with an appropriate pour point depressant (PPD) for best results. For advice on the exact amount and combination, contacting Chempol Ltd.’s technical team is best. This polymer is sold in bags of 25kg, 500kg, and even 1,000kg sizes.
