[ Properties ] density 1.*8 ; melting point of ****4 ° C; boiling point > **5 ° C; -soluble <0.1 g/**0 mL at *3 ° C

[Character]

Pale yellow to amber powder or flakes. Non-toxic.

[ Softening ]

*4 ℃ or more.

Issolved

Insoluble in water, soluble in benzene , chloroform, acetone and carbon disulfide. Slightly soluble in petroleum hydrocarbons.

[Use]

Mainly used for rubber antioxidant . Suitable for natural rubber and nitrile , styrene-butadiene , ethylene-propylene , and neoprene synthetic rubber. Protection against heat and oxygen caused by aging effect is excellent, but the protective effect of aging on the flex poor . AW and antioxidant required phenylenediamines or with the use of antioxidants . Is the manufacture of tires , hoses, tape, wire and other rubber products commonly used antioxidant. Since the rubber antioxidant RD good compatibility , when the discharge amount is still up to 5 parts , it is possible to increase the amount of antioxidant and improved aging properties of the rubber compound , under dynamic conditions used in rubber products such as tires a tread band and transport , it may be with or AW antioxidant ***0NA .

Preparation or sources ]

Aniline and acetone as raw materials and toluene as a dehydrating agent , hydrochloric acid as a catalyst in the polycondensation temperature of ******0 ℃ , neutralized and washed with water , atmospheric distillation , vacuum distillation , slicing , packaging and derived products.

Appearance: Amber to brown flake Softening point :*****0 ℃, Heating loss : ≤ 0.5%, Ash : ≤ 0.5% Main characteristics and applications - have antioxidant effects , suitable for almost all types of applications in a variety of situations elastomer, a wide range of temperatures apply. - Duration of the rubber of the rubber compound having a long-term heat aging effect. - Heavy metal compound can prevent oxidation - a high molecular weight , slower migration of the plastic material matrix , not blooming . Recipe Data - In the application of the adhesive , RD primary antioxidant in an amount between 0.5 to 3.0 parts . In the light products , if the color is not allowed , the amount should not exceed 0.5 parts . - RD generally does not affect the curing properties of natural rubber and synthetic rubber , but it will reduce the storage stability of neoprene . If the situation requires the use of ozone- resistant and anti flex fatigue properties , RD ***0 , and should be used . - Antioxidant Protection 0.**3.0 parts RD - Universal Protection against degradation 0.*- 1.0 parts RD *1.0 parts ***0 - High Performance Protection 1.**2.0 parts RD *1.**3.0 parts ***0 - EPDM peroxide vulcanization and NBR rubber compound using RD excellent heat resistance can be obtained , on the crosslinking density slightly . In such applications, a typical amount of 0.*5 to 2.0 RD parts . - In latex applications, if available allowing a slight coloring powder dispersion RD , dry amount of 0.5 to 2.0 parts . Packaging and storage conditions of plastic woven bag lined with polyethylene plastic bag ( or according to the requirements of foreign packaging ) , net weight *5 kg . RD should be stored in a cool, dry , well-ventilated place. Packaged product to direct sunlight.
