Product Description
Antioxidant H
1. Name: Antioxidant H
2. CAS: 74-31-7
3. Uses: It's used for those rubbers and latices of natural, styrene-butadiene, acrylonitrile-butadiene, cis-1, 4-polybutadiene, butyl, butylhedroxyl, cis-1, 4-polyisopreneetc, so that to possess them those properties such as good resistance to many times of flexure and chap-resisting, highten the elongating strength, strengthen the defending function to hot-oxygen, ozone and some harmful metals such as copper, manganese and so on, and do not influence vulcanization of those rubbers. It can be resolved manifold problems existing in the deep-color rubber products while antioxidant H is used together with antioxidant D. Moreover it can be also used as the hot-oxygen stabilizer for those engineering plastics such as polyethylene, polypropylene, polyamide, polyformaldehyde and etc to improve their climate-resisting performance. The referential dosage is 0.2-0.3%.
