KVIS is the trade name of polyisobutylene produced by Kothari Petrochemicals Limited. KVIS is a linear polymer of isobutylene of different molecular weights, and possesses excellent resistance to oxidative and thermal degradation. Polyisobutylene is chemically inert, hydrophobic and impermeable to water vapor or gas.The KVIS is a synthetic liquid polymer, which is a straight chain hydrocarbon structure of Polyisobutylene that is produced in a variety of grades through a rigid low temperature polymerization process. It is derived from raw material consisting of mainly Isobutylene. The compact straight chain structure results in brilliant moisture and barrier properties and is soluble in a wide range of organic solvents.All KVIS grades are colorless, non-staining and have little or no odor.Polyisobutylene belongs to the group of viscous and non-drying liquid polymers. The grades vary from low viscous oil to a high viscous liquid and with a degree of tackiness that is on the higher side. All these unique characteristics and its compatibility with a wide range of organic materials augment the performance properties of a wide range of products in various industries, and have made it one of the most sought after product in the world.
