Applications: NBC mainly use in styrene-butadience rubber, chloroprene rubber and chlorosul-funatated 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 0.3-0.5phr.
Storage: Stored closely in a cool, dry and well-ventilated area. Avoid exposure to direct sunlight.
Package: In 25kg cardboard barrels with plastic inner.
