Antiozonant 70-TBPA is a highly effective non-staining antiozonant for polychloroprene polymers. It can also provide good ozone protection for Nitrile/PVC blends, and polychloroprene blends with Natural Rubber or SBR, containing at least 30% polychloroprene by weight. In combination with ozone protective waxes, Antiozonant 70-TBPA will result in non-staining characteristics for Natural Rubber, synthetic poly-isoprene, SBR, and polybutadiene. |
