Rubber anti-aging agent is the main variety of rubber additives, the current global consumption of about 600,000 tons, about 40% of the total amount of rubber additives.
Rubber anti-aging agents can be divided into: p-phenylenediamine, quinoline, diphenylamine, naphthalene amine, phenol and phosphite ester.
Among them, the p-phenylenediamine group accounts for 56%, quinoline group accounts for 20%, and other anti-aging products such as phenols, diphenylamines, phosphite esters are less than 10%.
With the rapid development of rubber additives industry in Asia, especially in China, the production of rubber additives in western developed countries and regions is gradually shrinking.
Major foreign production enterprises continue to merge and restructure, increase industrial restructuring, enhance enterprise competitiveness, and seek new opportunities and space for development.
At present, the following major foreign anti - aging agent production enterprises.
The company is affiliated to Eastman chemical, the United States, is the original global product variety of the most complete, the largest scale of rubber additives manufacturers.

Fulex's leading product is insoluble sulfur, with a total production capacity of 200,000 tons/year and a monopoly position in the high-end market.
Lanxess chemical co., ltd. is a major foreign comprehensive rubber fertilizer production enterprises.
In the European market, its rubber accelerator and Chinese accelerator products compete;In Europe and North America, their rubber anti-aging agent TMQ competes with nanhua and comac.
Its predecessor is the United States Compton company, has been the acquisition of uniroy company rubber fertilizer and the United States great lakes company (formerly one of the world's largest plastic fertilizer companies), renamed in 2005 koju ya.
Subsequently, the company gradually shut down the rubber agent, especially the aging agent production equipment, to polyurethane elastomer, lubricating oil, surfactant, plastic agent production.
