At present, the development of domestic rubber processing aids is still hampered

Rubber processing aids known as the “MSG” in rubber and plastics industry,and today’s market on a wide range of rubber and plastic products, and all of its processing aids the quality and performance. However, the current development of domestic rubber processing aids still have the following problems: (1) The production process waste serious pollution. (2) Additives production intermediates, raw materials

The Problems of Domestic Rubber Additives

1.Additives product structure and variety structure is irrational, uneven quality. For example, in order to meet the requirements of high temperature, fast and efficient rubber processing technology, a large amount of efficient sulfonamide accelerators have been used abroad (the amount of which has reached 55% of the total market of accelerators), easy to prepare, low-tech thiazole accelerators The proportion has
