What is rubber accelerator DTPP? What are the main ingredients?

 Time of issue: : 2019-07--02

Rubber accelerator refers to a rubber vulcanization accelerator. The vulcanization of rubber is mainly carried out with sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators appear.

Rubber reinforcement filling system

 Time of issue: : 2019-07--19

The surface chemistry of carbon black particles, the roughness of the surface of the particles, and the crystalline state of the carbon black all have a certain influence on the reinforcing effect. The sulfonium group or hydroquinone group on the surface of the carbon black can react chemically with the olefin rubber during the mixing and vulcanization of the carbon black to play a reinforcing role.

How to choose a vulcanization accelerator?

 Time of issue: : 2019-07--22

The accelerator should make the rubber have a wide vulcanization flat curve during the most suitable vulcanization period, that is, the performance of the vulcanized rubber should not change significantly during this period, which is especially important for thick rubber products. Rubber is a poor conductor of heat. The surface of the vulcanized rubber material is inconsistent with the internal heat. The wide vulcanization flatness is a guarantee to avoid sulfur and make the product parts vulcanized uniformly.

We will encounter all kinds of rubber products in our lives: woven rubber bands, erasers, sports basketballs, footballs, sports shoes, boots, hoses, tires, bicycle tires and so on.

The history of rubber additives

 Time of issue: : 2019-10--22

1. The first generation of rubber additives [1839~1904] In this era, rubber additives are represented by inorganic vulcanization accelerators. The rubber industry has entered the era of inorganic vulcanization accelerators, but there are also problems such as low acceleration efficiency and poor vulcanization performance.
