Binder type can be customized. Except SBR, others binders, such as EPDM, NBR also can be available for.
APPLICATION:
PVI-80 is a scorch retader for NR and SR, which can be used together with all sulfenamide types or thiazole type accelerators to control process safety and avoid incipient cure, without any influence on vulcanization characteristics and cross-linking behavior. It can also obviously improve the stability of unvulcanized rubber in storage and decrease scrap rubber rate.
DOSAGE:
Usually 0.2-2.0phr, will be blooming if more than 5.0phr.
PACKING & STORAGE:
Net weight 25kg/PE bags lined carton; Net weight 600 kg/pallet.
Shelf-life:12 months in its original packaging.
Stored in a dry and cool place.
