Uses: pneumatic tire parts, solid tire, moving tape, rubber duct, rubber band,cable , automobile bumper,rubber articulates,and other products for general use in the rubber industry. All these products are in the dynamic work ng state, continuous or intermittent and therefore require protection from ozone. 4020 (6PPD) is highly effective in antioxidation and gives the rubber material excellent thermal fatigue property and bending strength and stiffness. 4020 (6PPD) also makes rubberres istant to the degradation catalyzed by copper and other metal.
Package: Paper-plastic complex package with inner polyethylene (or packed upon request from the clients) , net weight 25kg/pack. 4020 should not be piled up over one another and should be stored at a cool and dry place with ventilation. Direct sunlight should be avoided. Piling up over one another or a temperature of over 35οC will lead to abnormal compression of the product.
