Molecular Formula：C₁₉H₁₈N₂O₂S
Molecular Structure：

Molecular Weight：338.42
CAS NO.100-93-6
Specifications：

Properties：Gray powder or granule, non-toxic, relative density 1.23, melting point is not lower than 135 ℃, soluble in acetone and methanol, slightly soluble in ethylene dichloride, benzene, hot water and hot alkali solution, insoluble in gasoline and water.

Applications：TPPD is mainly used for antioxidantRD of the CR, NR, BR, SBR and latex, protection of ozone, oxygen aging is good, also can inhibit copper and manganese pollution, especially suitable for protective CR released chloride to the fiber materia damage during the period of aging . This product is easy to disperse, and can be added rubber directly, also can make into aqueousdispersion inject latex. And when this product is used for CR, if using in common with antiager ODA, best heat resistant performance, also can reduce the plasticity of unvulcanized CR, Reduce rolling shrinkage, and thus help to adjust the size of the semi-finished products. Mainly used in the manufacture of wire and cable, tires, v-shaped belt, seals, tape and light industrial goods.

Package：Kraft paper bags or paper barrel. 25 kg/bag (barrel).

Storage：Should be stored in a cool, dry, well ventilated place, packaged products should avoid direct sunlight.

Instructions: Can provide different purity products according to customer requirements; The product packaging can be adjusted according to customer's requirements.

Development prospects 

     The rubber additive is a general term for various chemicals which are added to the rubber during rubber processing and which can improve the rubber processing property, improve the quality of the rubber product, and reduce the cost. Rubber additives are important raw materials for the rubber industry. Rubber additives play an important role in the improvement of processing and application properties of rubber products. The rubber additives with excellent performance can not only improve the processing performance, improve the quality of products, reduce energy consumption and production. Cost, and can prevent aging degradation and prolong the service life of rubber products. Rubber additives products comply with national industrial policies:

     The "Industrial Structure Adjustment Guidance Catalogue" (National Development and Reform Commission (2011)), the eleventh item of the "encouraging category", "Petrochemical Chemicals", the 14th item "Environmental Catalysts and Auxiliaries" and the 17th item "High" Performance radial tires and supporting special materials are all related to the support of the rubber additives industry.

      According to statistics, nearly 90% of the application of rubber additives is related to automobiles, and 70% of its output is used for tire production. In recent years, with the continuous growth of the global automotive industry, high-speed railway and aerospace industries, the demand for rubber products will continue to flourish, and the rubber industry will continue to develop. At the same time, the eastward shift of the international rubber industry has also provided a rapid development opportunity for China's rubber auxiliaries industry. Especially in recent years, international rubber auxiliaries production enterprises have continuously shut down their production facilities, which has made the domestic industry gain greater development. Space, China's rubber additives industry has become increasingly dominant in the global market.
