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, speciality 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
 
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 carburettors, 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
 
Adhesives
 
» Kothari Polyisobutylene are vital ingredients in many pressure-sensitive adhesives (PSAs) and hot-melt adhesives (HMAs)
» Modify softness, tackiness, cohesive strength, and water resistance
» Polyisobutylenes are resistance to oxidation, no toxicity
» Examples of adhesives that can be improved with Polyisobutylene include: adhesives for surgical tapes; paper laminates, labels and tapes; masking and friction tapes; colourless adhesives; foil and fiber lamination; and industrial tapes.
 

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
Better for Pest Control
 
Kothari polyisobutylene is rapidly becoming the number one choice for pest control in agriculture, such as vineyards and other delicate crops.
 
» Tackiness of Polyisobutylene can increase the effectiveness of pesticides and insecticides
» High molecular weight PIB 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

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.
