Chemical Name: 1,4-Benzenediamine or N,N'-mixed phenyl and tolyl derivs Specification: Item Q. Index Appearance Brownish grey grain Dry sample primal melting Point (oC) 90-100 Thermal Loss(%, 65oC) â?¤ 0.5 Ash(%800 oC): â?¤ 0.3 Properties: Antioxidant DTPD (3100), which can be classified in p-phenlene antioxidant groups. Is excellent antioxidant to chloprene rubber. It is the effective antioxidant used in the tire industry and also widely used for rubber products.1.DTPD can resist ozone, its capacity to resist flexibility and cracking is similar to antioxidant 4010NA or 4020, superior to antioxidant AD.2.DTPD, particularly mixed with the same amount of 4020 or 4010NA. it is the most antioxidant style to extend the useful life of tire. The reason is that the two kinds of antioxidant have synergism. Antioxidant 4020 and 4010 NA provides the short-time protection at the beginning. While DTPD provides the long-term protection.3. Because of one or two soluble groups on the benzene rings in DTPD, the solubility in rubber is enhanced highly and the blooming is reduced, so that large quantity of DTPD can be used in rubber.4.DTPD has no influence on vulcanization and scorch owing to its little basic. DTPD is suitable for truck tire, cross country tire, diagonal tire and radial ply tire which is used in hard circumstanges.5.DTPD can also correct the fault that tire become red on the account of antioxidant 4010NA or 4020. at present many companies abroad is positively researching on this product instead of Antioxidant 4010NA. DTPD is widely used internal in diagonal tyre and radial ply tyre. Its application foreground is extensive. Application: DTPD is packaged in composite paper sack lined with film. Net weight is 25KG per sack. Packaging: Polypropylene knitted bags lined with polyethylene bags. Net weight 25kg per bag.. Storage: Anti-fire and water proofing should be done. DTPD should be stored in dry place.
