PACKAGING & STORAGE :
25 kg(net) Carton. 600 kg (net)/ pallet.
Shelf-life : 2 years in its original packaging
Store in a dry and cool place and away from direct sources of heat or sunlight.
Compared to a traditional EVM/EP(D)M binder, NURCHEM HEXA-80 allows :
l Raw materials 38µm are all under sifting, but no dust appears with master batch
l master batch H-80 is pre-dispersed with rubber carrier, thus can effectively ensure the activity of Accelerant H.
l No clay domain appears with master batch at room temperature
l Has low Mooney viscosity at low temperature such as 50°C to improve disperse quality
l While granulation, master batch can filtering to lower rejection rate.
l Has good compatibility with different rubbers
