Low Zinc active nano zinc oxide masterbatch
European Commission has confirmed the EU-wide ban on the use of zinc oxide at medicinal levels in piglet feed in 2017, EU 2017/1413 Regulation made further limit on zinc oxide in cosmetics, in 2016, California Senate Bill 1260 even tried to ban the sale of motor vehicle tires in California that contained more than a certain amount of zinc by weight. To follow this tread, we have developed Low-Zinc Activator Topfine® CR510, it has the characteristics of low zinc content, high vulcanization activity and excellent dispersion. Zinc content is only half of common Zinc Oxide (ZnO), which is environmentally friendly, and meets the requirements of rubber products performance.
Activator Topfine® CR510 is prepared by means of liquid phase reaction, which is obtained by reaction under specific temperature and PH conditions, also obtained under dehydration process and granulation technology.
PRODUCT HIGHLIGHTS
High activation efficiency
Nanometer grade dispersion, no agglomeration
Good dispersity of processing, no dust
Excellent physical properties (comparing with equivalent ZnO indirect Process), can replace ZnO-80 Masterbatch equivalently)
Environmentally friendly, Zinc content 40%
Effectively increase the scorching time, improve the processing safety, the vulcanization speed faster than that of the common zinc oxide.
Low content of heavy metal, passed SGS test, meet RoHS standard
CR510
Pre-Dispersed Polymer Bound Chemicals
function
Metal Oxide
A homogeneous mixture of Zinc Oxide and polymeric binder system at 80/20 ratio
The elastomer bound form of CR510 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 .
Dosage
3 - 8 Phr
Packaging
25 kgs in carton box with polyethylene bag liner or Valve pocket
Storage
Keep cool (below 25 ) and dry in original package.24 months from production date
characteristic
It can replace ZNO80 very well with low zinc , ECO-friendly.
