| 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. |
| Storage: |
Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight. |
| Packing: |
Coextruded paper bags lined with polyethylene film bags. Net weight 25 kg per bag. |
