Polybutene KVIS 200

Description

What is Polybutene KVIS 200?

Polybutene KVIS 200 is a high molecular weight, viscous liquid polymer derived from isobutylene. It is widely recognized for its superior tackiness, excellent lubricating properties, and thermal stability, making it an ideal ingredient in a wide range of industrial, automotive, and specialty chemical applications. With its high viscosity index and consistent performance, Polybutene KVIS 200 is commonly used as a thickener, plasticizer, tackifier, and performance enhancer in lubricants, adhesives, sealants, and coatings. Its chemical stability and low volatility make it reliable even under demanding operating conditions.
