POLYVEST®

ADVANCED REACTIVE RESINS

With POLYVEST® we offer a range of advanced reactive resins 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 polybutadiene grades products such as POLYVEST 130 offer the opportunity for various crosslinking options, like sulfur curing and oxidative drying. Our functionalized POLYVEST® grades provide further options for crosslinking and additional benefits.

Key benefits of POLYVEST® advanced reactive resins

Low viscosity
Excellent chemical resistance to acids and bases
High water resistance
Excellent electrical insulation properties
Low temperature flexibility
Low moisture and oxygen permeability

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.
