Properties:

Dark-green powder/granules. Density is 1.26g/cm3. Flash point is 260°C. 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.
