POLYVEST®

LIQUID POLYBUTADIENES

With POLYVEST® we offer a range of stereospecific, low viscous and unsaponifiable liquid polybutadienes with different chemical compositions.

Based on their characteristic microstructure, all POLYVEST® grades exhibit excellent reactivity and can be used for a broad variety of applications, e.g. in the automotive, construction and electronics industry.

The unsaturated polymer backbone of our liquid polybutadienes offers the opportunity for various crosslinking options, like sulfur curing and oxidative drying. Our functionalized POLYVEST® grades provide further options for crosslinking and additional benefits.

Mechanical Rubber Goods

POLYVEST® is used as a binder for recycled rubber compounds, modifier in carbon black filled EPDM compounds and as plasticizer in rubber compounds.

Construction

POLYVEST® grades are used in secondary sealants for window glazing, in binder of dusty and dry quartz sand as well as in binder for soil stabilization. Moreover, POLYVEST® can be added as modifier to silicone sealants.

Electronics

POLYVEST® can be used as binder in PU formulations regarding electrical insulation and potting compounds. POLYVEST® MA can substitute isocyanates and act as isocyanate-free hardener.

Flexo Printing Plates

POLYVEST® is employed as reactive plasticizer for flexo printing plates and as pigment wetting agent for offset printing inks.
