Binder type can be customized. Except EPDM, others binders, such as SBR,NBR also can be available for.
APPLICATION:
The elastomer bound form of ZnO-80 ensure better physical properties and surface quality for extrusion profiles than powder form.The vulcanizates will obtain higher modulus and tensile strength,prevents scorch in chloroprene rubber compounds due to the localisation of powdered form zinc oxide
DOSAGE:
3-8 phr usually.
