Polyisobutylene from Kothari is better for your business, and better for the environment:

Better for Lubricants
 
Kothari Polyisobutylenes demonstrate very low deposit formation. Unlike typical lubricants, our Polyisobutylenes depolymerize cleanly when heated above 250 degrees celsius
 
» Low toxicity
» Good thickening properties
» High shear stability
 
Applications include: non-staining metal lubricants, specialist compressor lubricants, low toxicity/energy efficient gear oils and greases
 
Better for Two Stroke Engine Oils
 
Kothari Polyisobutylenes are a proven cost effective alternative for lowering emissions in two-stroke engines — a chief concern among many countries with increasingly strict environmental standards
 
» Cleaner burning
» Reduced corrosion and scoring
» Elimination of engine deposits
 
Kothari Polyisobutylenes offer enhanced performance compared to most other Polyisobutylenes
 
Better for Oil and Fuel additives
 
In engine oils, derivatives of Kothari Polyisobutylenes are used as ashless dispersants (such as PIBSA) to minimize deposits and prevent oil thickening and formation of sludge. These Polyisobutylene-based additives
 
» Improve fuel economy
» Provide environmental benefits due to lengthening the life of oil in the engine, and providing cleaner-burning engines
» For gasoline engines: reduce deposit formation and removes deposits already present in carburetors, fuel injectors and intake systems, valves and pistons
» For diesel fuel: used to clean fuel injectors
 
Better for Stretch/Cling Wrap Films
 
Higher grade Kothari Polyisobutylenes, such as KVIS 30 and KVIS 200 are often used in cling wrap, due to their tackiness, good clarity, clinging properties and durability .
 
» Examples include film, stretch wrap, bale silage wrap
 
We are fully capable of customizing our polyisobutylene viscosities and grades to suit your unique needs.
 
 
Better for Adhesives & Sealants
 
Pressure Sensitive Adhesives
 
» Kothari Polyisobutylene's are vital ingredients in many pressure-sensitive adhesives (PSAs) and hot-melt adhesives (HMAs)
» Modify softness, tackiness, cohesive strength, and water resistance
» Polyisobutylenes are better than mineral oils due to low color, resistance to oxidation, no toxicity
» Examples of adhesives that can be improved with Polyisobutylene in-clude: adhesives for surgical tapes; cements for leather; paper; paper laminates, labels and tapes; masking and friction tapes; colourless adhesives; foil and fiber lamination; and industrial tapes.
 
Water Based Pressure Sensitive Adhesives
 
» Polyisobutylene emulsions minimize organic vapor emissions in water-based pressure sensitive adhesives
» Less expensive: These emulsions also offer enhanced adhesion and temperature stability while lowering adhesive costs for packaging, labels, and product assembly
 
Hot Melt Adhesives
 
» Kothari polyisobutylenes perform as a polymer extender, plasticizer, tackifier and wetting agent
» Polyisobutylenes decrease the melt index and increases the cold temperature flexibility
» Examples include: packaging, disposable soft goods, carpet, shoes, and furniture, book binding, carton sealing
 
Sealants
 
» Kothari polyisobutylenes plasticize and add tack to elastomer based sealants.
» They are softer and more easy to use as sealants
» Less utilization of solvents, which is environmentally beneficial
 
Kothari polyisobutylenes are often used as a replacement for drying oils in sealant and putty formulations
 
» Improved stickiness, or adhesion
» Longer life
» Less shrinkage
» Lower oil to filler ratios
 
Better for Paints & Coatings

 

Our polyisobutylenes are a viable alternative to acrylic bases, since they improve water repellency and result in lower manufacturing costs

» Water resistance
» Low color
» Plasticization
» Better adhesion
» Replaces volatile solvents
 
Examples include: waterproofing for porous substances, such as wood or concrete, hot-applied thermoplastic road marking paints, masonry paints
 
Environmentally Friendly Pest Control
 
Kothari polyisobutylene is rapidly becoming the number one choice for environmentally friendly pest control in agriculture, such as vineyards and other delicate crops.
 
» Tackiness of Polyisobutylene can increase the effectiveness of pesticides and insecticides
» KVIS 200 can be used to physically trap insects, and are often used in vineyards and other delicate crops as a non toxic method of pest control
» Mixed with low molecular weight polyethylene, the resultant tacky gel can be used for tree banding to trap tree climbing pests

Better for Electrical Insulation Applications
 
Kothari Polyisobutylenes are hydrophobic and non-conductive, and are thus used as electrical insulation across a wide range of applications. Its low chloride content and high level of purity result in resistance to oxidation and gas evolution under electrical stress.
