A7750 77PD CAS 3081-14-9 N,N’-BIS(1,4-DIMETHYLPENTYL)-P-PHENYLENEDIAMINE
Introduction
Chemical Name :Mixture of N,N’- bis(1,4- dimethylpentyl) – p- phenylenediamine and black carbon N 330
CAS NO. :3081-14-9
Product Specification:
| Appearance | Black particle | |
| Heat Loss(70℃),% | ≤ | 2.0 |
| Ash,% | ≤ | 1.0 |
◆Performance:
-A7750 is a mixture product of antioxidant 77PD and carbon black N330, which is convenient to weighing and dispersion.
-A7750 has the same performance as antioxidant 77PD, which is suitable for natural rubber and synthetic rubber products. It has excellent static ozone aging resistant performance, and can improve flexing fatigue resistance to some extent.
◆Application:
-Suitable for tire tread, sidewall compounds, improving static ozone resistant performance.
-Applicable to wires & cables, rubber pipes, taps, and other outdoor rubber products that are in long-term static state.
-Separately used for rubber products having high requirements for static ozone aging resistance.
-A7750 can be used in natural rubber and synthetic rubber products to improve cracking, discoloration, while usually used with IPPD, 6PPD together, to improve dynamic ozone aging resistance and flexing fatigue properties.
◆Packaging:Paper/plastic packages with a net weight of 25kg per package.
◆Transportation Condition:Transportation Conditions for general chemicals are sufficient.
