| POLYVEST® MA 75 is a maleic anhydride adduct of a low molecular weight 1,4-cis polybutadiene which as succinic anhydride groups randomly distributed along the polymer chains. This makes the originally apolar polybutadiene more polar and accessible for various chemical reactions. General Use and Applications: Due to its high content of 1,4-cis double bonds the a polar, hydrophobic hydrocarbon resin POLYVEST MA 75 is a highly reactive binder featuring the following characteristics: - high chemical resistance
- high water resistance
- high electrical insulation properties
- high cold resistance
- good solubility in alphatic, aromatics and ethers
- good compatibility with hydrocarbon resins, rosin resins and zinc resonates
In this form POLYVEST MA 75 is used in the following areas of application:- adhesive and sealant compositions
- electrical insulations and potting compounds (2pack systems)
- polymeric chalk activator in EPDM-compounds
- modifier in carbon black filled EPDM-compounds
- modifier in silica filled rubber compounds
- modifier in rubber compounds for car tires
- modifier in silicone sealants
