Pressure-sensitive adhesives (PSAs) and hot-melt adhesives (HMAs) of various types utilize KVIS polybutene as a key constituent.

 

 

» Tack

» Softness

» Bond strength

» Cohesive strength

» Water resistance of adhesives

 

 

» Low colour

» Excellent colour stability

» Good resistance to oxidation

» Practically no toxicity

» 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.

 

 

» 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,

 

 

» Polymer extender

» Plasticiser

» Tackifier and

» Wetting agent

 

Polybutene increases the cold temperature flexibility and decreases the melt index.

 

The major applications for these Heat Melt Adhesives include

 

» packaging

» 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.
