Properties Dark-green Power. Density is 1.26g/ cm3 .
flashing point is 260 ? . Soluble in chloroform, benzene and carbon
bisulfide , a little soluble in acetone, insoluble in water.
Applications Mainly use in styrene- butadience rubber,
chloroprene rubber and chlorosul-fonated polyethylene rubber. Avoiding
the rubber crack for the sunshine and ozone, promoting the
heat-resistant of chloroprene rubber and chlorosul-fonated polyethylene
rubber. In plastic industry, it can be used as stabilitant and
ozone-resistant agent for high polymer materials. It has advantage of
stability for polypropylene fibre , thin film and narrow belt, but it
will make the products appear yellow-green color. The use level is
0.3~0.5%. NDBC is regulated for use in articles in contact with food as
specified under BgVV XXI, Category 4.
Packing Coextruded paper bags lined with polyethylene film bags. Net weight 25 kg per bags.
