KVIS Polybutenes are used in manufacture of PIBSA, a widely used dispersant in lubricant industry.
PIBSA is used as ashless dispersant in the lubricant formulations to control deposits, sludge formation and to prevent oil thickening.
PIBSA based dispersant can help in improving the fuel economy. They also offer environmental benefits by decreasing the frequency of oil drains.
Diesel Engine Oil Additives
Polybutene based fuel / gasoline additives helps in reducing the deposits. They also remove the deposits already present in the automotive components like carburetors, fuel injectors and intake system, and on valves and pistons. Polybutene based additives in diesel can help to maintain cleanliness of the fuel injectors, again leading to fuel economy.
Polybutene is widely used in lubricant for modifying / improving the viscosity of the lubricant formulation to the desired final viscosity.
Polybutenes are widely used in applications where there is a plenty of chances for incidental contact of the lubricant with food such as production of aluminium foils and cans.
KVIS polybutenes are inherently good lubricants and its unique physical properties make them a perfect choice for wide variety of lubrication requirements.
The wide range of viscosities of the KVIS polybutenes offer the operational comfort to the lubricant formulators i.e the formulators would have a considerable scope to devise and optimize the formulations of the lubricants
The typical advantage of KVIS polybutenes over other polybutenes is property of very low deposit formation. When heated above 2500 C they will depolymerise.
The notable characteristics of KVIS PIB are very low toxicity and good thickening capacity.
KVIS polybutenes exhibit excellent shear stability.
KVIS polybutenes are widely used in Non staining metal working fluids, High temperature / specialty lubricants, high viscous / energy efficient gear oils and greases.
KVIS polybutenes are used as a functional component in many special purpose paints and coatings.
The notable advantages of polybutene in such applications include
» Water resistance,
» Low colour,
» Plasticization of the final film,
» Excellent adhesion and
» Ability to replace volatile solvents.
Manufacturing costs can be lowered using polybutene emulsion formulations and inclusion of polybutenes in the formulation helps to improve water repellency than the commercial acrylic-based systems.
KVIS polybutenes can be employed in the following coating applications:
» Hot-applied thermoplastic road marking paints
» Masonry paints (as an environmentally acceptable alternative to chlorinated plasticizer) and
» Waterproofing protection for porous substrates such as wood or concrete.
Pressure-sensitive adhesives (PSAs) and hot-melt adhesives (HMAs) of various types utilize KVIS polybutene as a key constituent.
Polybutene addition attributes to modification of properties like
» Bond strength
» Cohesive strength and
» Water resistance of adhesives
Polybutene is superior to mineral oil in offering the advantages like
» Low colour
» Excellent colour stability
» Good resistance to oxidation
» Practically no toxicity, and
» A wide range of viscosities
Formulation cost can be reduced by using high molecular weight / viscous grades as a partial or total replacement for the expensive resins.
Pressure-sensitive adhesives which can be improved with polybutene include:
» Surgical tapes
» Industrial tapes
» Adhesives for paper laminates, labels and tapes
» Masking and friction tapes
The tackiness of the natural and synthetic rubbers can be improved by polybutene. It also helps in improving the quick stick and peel strength of elastomers.
Polybutenes attribute to various vital functions when incorporated into hot-melt adhesives,
Polybutene acts as a
» Polymer extender
» Tackifier and
» Wetting agent
Polybutene increases the cold temperature flexibility and decreases the melt index.
The major applications for these Heat Melt Adhesives include
» disposable soft goods
» book binding
» carton sealing, carpet, shoes, and furniture
Polybutene aids in improving the tack and adhesion of the tie layer in multi-layer food packaging applications.
KVIS polybutenes are pure, clear and practically non-toxic polymers.
Personal care products like lip-gloss and roll-on deodorants can be formulated with polybutene.
Because of high purity KVIS polybutenes, it can be used to replace fatty esters and other expensive oils in the personal care product formulations.
